The Mind a Central Processing Unit
The mind our CPU
The Mind is a Central Computing Unit (CPU) in all sense of the word, because every organ, tissue, muscle, bloodstream, vein, and molecule is gauged by the mind through neurons.
The mind and our brain is made up of neurons called nerve cells where the body sends messages to other parts of our body and organs; it is better known as our Central Computing Unit, our brain. The body has sensory receptors at the ends of our fingers, as well as on the skin, where it sends messages to our brain when we feel pain, our temperature changes, or when we tear or puncture the skin. When the message is received the brain organizes the message to respond to the sensory message in the area of the brain, where it needs an alert or response (predestined cellular instructions that were derived when we were born). For example, If I burn my finger, the neuron messenger travels to the middle of my brain (Central Fissure) specifically for messages involving pain, then transfers a message back to the hand to reflex or remove my finger from the spot causing the pain, and the reflex of pulling the finger away kicks into play. The neurons have specific instructional messages and can only go to certain types of organs or muscles in the body where it is designated to go by the part of the brain that is the authorized or delegated to do so, by a predestined cellular instruction, to carry out the destinations instructions.
The left side of the brain is a receptor of speech and is the analytic side of the brain. It processes language and analyzes the subject.
The right side of the brain is the holistic processing. It maintains the memories we make. Our brain is the conductor of our cognitive skills and the left side is pre-dominating.
Our brains are plasticity therefore making them adaptable to changes in environment and reaction to injury. The Brain and Spinal Cord is the Nervous system to our bodies. The brain is the main central processor and the spinal cord carries neurons to every part of our body, through the bloodstream. The neurons are the messengers of the brain. Neurons come in all kinds of different shapes and they are in different sizes also. They have specific functions; specific instructions in their message environment and in the Endocrine system where glands secrete chemical messages into the blood, and Oxygen is where they can specifically go to the organs or muscles that the brain delegates by its instruction. That is an internal control so that they are not all over the place. They also transmit messages from one to another to different neurons and they do that with dendrites (micro-cells) that are receptors shaped like trees.
There are three types of neurons:
· Sensory – carry messages to brain and spinal cord have receptors
· Motor – carry messages from spinal cord or brain to muscles or organs
· Interneuron’s – carry messages to another neuron
These Neuron-transmitters form the parts of the body that conduct messaging and is the activator for our emotions and behaviors. Our brain is the organizer that organizes these messages into reactions or responses from the separate divisions in our brains.
The brain has several different parts it is divided into hemispheres. They are:
· Cerebellum – Structure of the hindbrain that controls certain reflexes and coordinates the body’s movement.
· Midbrain – Region between the hindbrain and forebrain; it is important for hearing and sight this is where pain is registered
· Thalamus – Forebrain region that relays and translates incoming messages from sense receptors, except those for smell.
· Hypothalamus – exerts enormous influence on many kinds of motivation (hunger, thirst, etc.) and is directly involved in Emotional behaviors.
· Hippocampus – Formation of new memories and governs the regulation of emotions so does Amygdale
· The Cerebral Cortex is a ballooning out and over the systems named above covering and hiding them beneath the cerebral cortex called the cerebrum.
· Frontal Lobes – seem to permit and anticipate goal oriented behaviors and when impaired can cause shifts in behaviors that could cause debts, betrayal with spouses, and abandonment with family and friends.
The Human Cortex could reach about 2 to 3 square feet in length, accounts for about 80% of skulls weighting 70% where it is made up of the neurons in the central nervous system.
