Nervous System: Master Controlling and Communicating System of the Body

Updated on August 23, 2014

Nervous System

The nervous system is the master controlling and communicating system of the body. It serves as the chief coordinating agency. Conditions both within and outside of the body are constantly changing. Through the instructions and directions of the nervous system to the various organs, a person’s internal harmony and balance between him and his environment is maintained. The nervous system is compared to a telephone communication system wherein the brain and the spinal cord act as switching centers and the nerve trunks act as cables for transmitting messages to and from these centers. The nervous system has three overlapping functions: to monitor changes (stimuli) occurring inside and outside the body and to gather information (sensory input); to process and interpret the sensory input in order to make decisions (integration); and to activate the muscles or glands (motor input).

Structural Classification of the Nervous System

Central Nervous System

The Central Nervous System is consists of the brain, the spinal cord and the nerves that extend from the spinal cord. It could be compared to an electrical communication station. The brain is like a switchboard, receiving and answering messages continuously. The spinal cord is the main cable through which incoming and outgoing message flow. And the nerves are the wires that run from the main cable to the remote corners of the body, leaving no area without a signaling device. The incoming messages are carried on a network made up of the sensory nerves. The answers are delivered by way of a companion network composed of the motor nerves.

The Brain

The brain is a mass of nerve tissue occupying the cranial cavity and is covered by membranes, fluid, and the bones of the skull. It is a little over three pounds. It is the largest and most complex mass of nervous tissue in the body. It controls all our thinking and all our nerve activities.

Spinal cord

Almost all the sensory and motor nerves that activate the muscles extend from the spinal cord. The cord is a long cable-like structure made up of hundreds of nerve fibers, which is approximately 17 inches (42 cm) long. It is suspended in the bony canal formed by the long string of vertebral, bashed by a clear fluid called the spinal fluid and enclosed within the vertebral column. The cord runs up the spine and through the opening of the bottom of the cranium where it expands and becomes the brain. It extends from the foramen magnum of the skull to the first and second lumber vertebra. It provides a two-way conduction pathway to and from the brain. It is also a major reflex center where the spinal reflexes are completed.

Neuron

Parts of the Neurons

Neurons are composed of the following:

  1. Cell body which contains the nucleus and is the metabolic center of the cell; and the
  2. Nerve processes or fibersextending from the cell body composed of:
  • Dendrites - the nerve processes that conduct impulses towards the cell body. Each of them functions as receptor, where a stimulus is received and the sensory impulse begins.
  • Axons - the nerve processes that conduct impulses away from the cell body. When these impulses reach the axonal terminals they stimulate the release of chemicals called neurotransmitters into the extra cellular space. The axonal terminals are separated from the next neuron by a tiny gap, the synaptic cleft. This is what we call synapse which is the region of communication between neurons. Some axons in the central and peripheral nervous systems are covered with a fatty insulating material called myelin. Axons covered with myelin are called white fibers found in the white matter of the brain and spinal cord as well as in the nerve trunks in all parts of the body. The fibers and cell bodies of the gray matter are not covered with myelin. A thin outer sheath called neurilemma covers the myelinated axons of the peripheral nervous system. Neuralgia supports and protects neurons in the central nervous system. A nerve impulse is an electrochemical event that causes change in neuron plasma membrane permeability allowing sodium ions to enter the cell.

Neurons

Neurons

Neurons are also called nerve cells. They are highly specialized to transmit nerve impulses from one part of the body to another. All living tissue is composed of tiny, microscopic bits of matter or cells. The cells that make up the nervous system are called neurons. All cells react to stimulation, but none in the unusual way that neurons do. Neurons are capable of transmitting an impulse to its neighboring cell. The billions of neurons packed together into the nerve paths deliver a message to the brain in the following way. The impulse travels rapidly in one direction; each neuron disturbing the next one along the route of a sensory nerve until the section of the concerned organ or body part is informed. The response is flashed back in identical manner through a motor nerve to the muscles it activates. The first neuron in a sensory nerve that is stimulated starts a chain reaction that ends with the contraction of a muscle through a motor nerve.

      The nervous system monitors the internal and external environments. Integrates sensory information and coordinates voluntary and involuntary responses of many organ systems. These functions are performed by neurons supported and protected by neuroglia. The major divisions of the nervous system are shown in the diagram below.

      The central nervous system consisting of the brain and spinal cord integrates and coordinates sensory data and motor commands. The CNS is also the seat of higher functions such as intelligence, memory and emotion. All communication between the CNS and the rest of the body occur through the peripheral nervous system or the PNS.

      The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. This is the boss of our body. Because without nervous system we human can't move because no one will signal the brain to move. Nervous System is our boss.

      The nervous system along with the endocrine system coordinate the actions of the body. Through a series of adjustments, all systems of the body are regulated to ensure effective behavior and to maintain the internal environment within safe limits. Responses to internal and external environment are made possible by either electro- mechanical message relayed from the brain, or by a series of messengers, called hormones are produced by glands and require more time for responses. The nerves is do this faster.

      The nervous system is responsible for sending, receiving and interpreting information from all parts of the body. Just like what's the essence of being an accountant we send and receive quantitative data and we interpret all of the gathered data in order to give our clients a reliable financial statements needed by their firm/business. All of us our given the command center known to be the brain in order to perceived and understand the happenings in our surroundings. The brain has parts that made it perform its task. It is our brain that upholds all the memories from the past, the source of information and helps an individual to think properly on how to respond to usual or even unusual situations in life. It is really astonishing how our brain do a number of function which I, myself cannot imagine. So in company the boss serves as the brain but not all the time because accountants or even other members of the company may voice out their scheme for the progress of the business.

      I consider nervous system as the most important among body systems. Because without it, the other body systems would not function and of course, would cause death eventually. So by learning its importance, I can make efforts to protect my nervous system and keep the information in me, flowing. It would be very beneficial to me since my course demands a lot of information processing.

      The nervous system is made up of nerves, the spinal cord and the brain. The nerves control everything we do, they carry messages that tell us to move, to breathe, to feel and to think. The nervous system allows us to perceive, comprehend, and respond to the world around us. If there was no nervous system, our heart wouldn't be told to beat, our legs wouldn't be told to walk and we will not be able to do certain things. Nerves help us to feel things.

      The nervous system is the mastermind of all our actions. Its importance cannot be denied. It's role is vital to all the parts of our body. Being the mastermind of everything, it leads the body to coordination and action. As a future professional, we must learn know how to take the lead. We ought to know how to be a leader. Being a leader means one must be tough. One must have the backbone to support his or her members. It is not just their lives that is rested upon your hands but also the families they support. We must know how to make sound decisions that will benefit all or most. Being the leader doesn't mean you'll just command. You must also work with them. By doing this, we can gain harmony and be able to work more efficiently with one another.

      The Nervous System or also called The Master Controlling and Communicating System of the Body plays a vital role in the human body. It is the one that commands the body of what to do and of course it is also the CPU that input commands and task to our bodies that will execute the command given by the Central command or the Brain. Just like in the business, a worker without a manager that leads them the business will not be a success or just like an Platoon of soldiers without a leader they will mostly failed or die in the mission. The is why this is the leader or the commander of the human body because without the order and command of the nervous system the body is useless.

      The nervous system acts to tell our body when something occurs or help notice things that only humans would. Changes in temperature, changes in light, pain or pleasure, touch, tension and stress. It is our brain's way of telling yourself what is happening to your body. For instance, when you get sick you may feel a headache or a pain from a scratch, it lets your body know that you are sick and your body is fighting infection or that you need to revise your mistake and not do something again because it is harming your body.Our nervous system is what creates feeling and movement throughout your body. Basically, the nervous system carries signals from your brain to other parts of your body so you can function

These vital systems of the body are being performed even when the body and other bodily systems are in a resting state. Signals sent from the brain through the nervous system control all body functions such as thoughts, the way you move your body, and even how well you learn and remember things.

      The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. It controls both voluntary action (like conscious movement) and involuntary actions (like breathing), and sends signals to different parts of the body. The central nervous system includes the brain and spinal cord. The peripheral nervous system consists of nerves that connect every other part of the body to the central nervous system. This system is so important because it is what makes us feel things. Without it we wouldn't be able to feel a thing. It also carries messages around our bodies from our brains so we can do things.

      Nerves are cylindrical bundles of fibers that start at the brain and central cord and branch out to every other part of the body. Neurons send signals to other cells through thin fibers called axons, which cause chemicals known as neurotransmitters to be released at junctions called synapses. Therefore, the nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body.

The nervous system has three general functions: a sensory function, an interpretative function and a motor function. Sensory nerves gather information from inside the body and the outside environment. The nerves then carry the information to central nervous system (CNS). Sensory information brought to the CNS is processed and interpreted. Motor nerves convey information from the CNS to the muscles and the glands of the body.

      The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.e brain and the spinal cord make up the central nervous system. They are wrapped in a thin lining called meninges and bathed with cerebrospinal fluid (CSF). Nerves connect the brain and spinal cord to the peripheral nervous system, which is what nerve tissue outside of the central nervous system is called. It is made up of two main parts: the autonomic and the somatic nervous systems.

      Angeles, Nikka Lei S. BSA 1-4 The nervous system is responsible for the control of the body and the communication among its parts. It is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. The nervous system has three general functions: a sensory function, an interpretative function and a motor function. Sensory nerves gather information from inside the body and the outside environment. The nerves then carry the information to central nervous system (CNS).

      MARYROSE CRUZ BSBA 1-1 The basic functioning of the nervous system depends a lot on tiny cells called neurons. The brain has billions of them, and they have many specialized jobs. For example, sensory neurons take information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain and back to the rest of the body.The nervous system is the path along which your brain sends and receives information about what is happening in the body and around it. This path is made up of billions of nerve cells, or neurons which join together to make nerves.The nervous system is the master controlling and communicating system of the body. It serves as the chief coordinating agency. Conditions both within and outside of the body are constantly changing.

      The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system. According to the National Institutes of Health, the central nervous system is made up of the brain, spinal cord and nerves. The peripheral nervous system consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect to one another and to the central nervous system. Functionally, the nervous system has two main subdivisions: the somatic, or voluntary, component; and the autonomic, or involuntary, component. The autonomic nervous system regulates certain body processes, such as blood pressure and the rate of breathing, that work without conscious effort, according to Merck Manuals. The somatic system consists of nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin.

      The basic functioning of the nervous system depends a lot on tiny cells called neurons. The brain has billions of them, and they have many specialized jobs. For example, sensory neurons take information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain and back to the rest of the body.

      All neurons relay information to each other through a complex electrochemical process, making connections that affect the way we think, learn, move, and behave. In accountancy, accountants acquire information from business documents and they use this to relay the firm or the corporation's standing to users of financial info as they produce legitimate financial statements.

The brain lies protected inside the skull and from there controls all the body functions by sending and receiving messages through nerves. Relating it to our field is simply CLEAR COMMUNICATION and COOPERATION makes the TEAMWORK.

      The nervous system is an organ system in charge of sending messages to and from the brain and spinal cord to and from all parts of the body , the brain tells the body how to react when a message comes into the brain from anywhere in the body. The relevance of this topic in our course is that how the professors teach us in able to get a message or facts on what we are going to do to be an accountant in the future.

      If you think of the brain as a central computer that controls all bodily functions, then the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back and contains threadlike nerves that branch out to every organ and body part.

      When a message comes into the brain from anywhere in the body, the brain tells the body how to react. For example, if you accidentally touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away. Luckily, this neurological relay race takes a lot less time than it just took to read about it.

      The nervous system is the one that serves as the control and communication system of the body. The receptors travel through the nerves of the body specially in the spinal cord to be send in our brain that usually gives us the decision and direct our action in our environment. Without this we can't usually answer or respond in to our environment.

      Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.

      Nerves are cylindrical bundles of fibers that start at the brain and central cord and branch out to every other part of the body.

      Neurons send signals to other cells through thin fibers called axons, which cause chemicals known as neurotransmitters to be released at junctions called synapses.

      The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system. Neurons send signals to other cells through thin fibers called axons, which cause chemicals known as neurotransmitters to be released at junctions called synapses, the NIH noted. A synapse gives a command to the cell and the entire communication process typically takes only a fraction of a millisecond. Sensory neurons react to physical stimuli such as light, sound and touch and send feedback to the central nervous system about the body’s surrounding environment.
