MCQs on "Muscle Stretch Reflexes" Tendon Stretching

When I was an undergraduate student, I always felt intimated by the post graduates who roam around with a hammer and keep knocking at the knees and elbows of patients. I used to wonder at the ease with which they elicited reflexes. It was effortless for most of them. Then I realized that there has to be a particular pattern to elicit these and one has to be thorough with the anatomy of these muscles.

This article is bout deep tendon reflexes; and how you can elicit them. Please read standard text books before starting to answer.

1. Origin of the long head of biceps muscle is from

A. supraglenoid tubercle of scapula

B. coracoid process of the scapula.

C. infraglenoid tubercle of the scapula

D. acromion process of scapula

2. The common tendon of triceps is inserted into the

A. olecranon process of the ulna

B. trochlear notch of ulna

C. coronoid process of ulna

D.Ulnar tuberosity

3. Nerve supply of brachioradialis is from

A. Radial nerve

B. Median nerve

C. Ulnar nerve

D. Musculocutaneous nerve

4. Vastus lateralis is supplied by

A. Femoral nerve

B. Obturator nerve

C. Lateral cutaneus nerve

D. Sciatic nerve

5. Achilles tendon is inserted to the posterior surface of the

A. calcaneum

B. Talus

C. Cuboid

D. Fibula

6. What is the connective tissue that surround individual muscle fibres called?

A. voltage gated Ca channel

B. voltage gated K channel

C. voltage gated Na channel

D. None of the above

10. The release of acetylcholine at the neuromuscular junction is caused by the influx of

A. Ca²⁺

B. K⁺

12. Muscle stretch reflexes are those that are ellicited in response to application of the stimulus to

A. tendon

B. bones

C. joints

D. All the above 

13. The banding pattern in each cell of skeletal muscle is attributed to -------
