Question

An axon emanating from a motoneuron in the spinal cord that excites a muscle in the thumb during the act of drawing a picture is part of what component of the peripheral nervous system?

a. sympathetic
b. parasympathetic
c. somatic
d. none of the above

Answer 1

The correct answer will be option-C.

Step-by-step explanation:

The peripheral nervous system is categorized into two types: somatic and autonomic nervous system. The somatic nervous system controls voluntary actions while the autonomic system controls the involuntary actions.

The movement of thumb while painting is a voluntary action which is under the control of the CNS. The brain and spinal cord send the signals to the PNS through the motor neurons which transmit it to the muscle and triggers response.

Thus, Option-C is the correct answer.
