Question 6

Which of the following is an incorrect statement regarding the occurrence of a sensation?

Accepted Answer

Question 9

Speculate about the benefit of having the nerve supply of the diaphragm, which is located in the thoracic- lumbar area of the spinal cord, arise from cervical nerves.

Accepted Answer

The fact that the phrenic nerve originates so high in the spinal cord reduces the likelihood of spinal damage above the phrenic origin, thereby reducing the possibility that a spinal injury would stop the diaphragm from working.

Question 11

The flexor muscles in the anterior arm (biceps brachii and brachialis)  are innervated by what nerve?

Accepted Answer

A)   ulnar
B)   median
C)   radial
D)   musculocutaneousE) All of the above
F) C) and D)

Question 12

Define tendon organs and muscle spindles relative to the stretch reflex.

Accepted Answer

Tendon organs work with muscle spindles to act as proprioceptors in skeletal muscles and their associated tendons. When muscles are stretched due to contraction of antagonist muscles, the spindle neurons send impulses to the spinal cord, where they synapse with motor neurons of the stretched muscle. Impulses are then sent to the stretched muscle, which then resists further stretching. At more severe degrees of stretch, the tendon organs inhibit rather than increase resistance to stretching in order to prevent muscle tissue damage.

Question 13

The musculocutaneous nerve is a major nerve of the brachial plexus.

Accepted Answer

A) True 
 B)False
