Question

Imagine that you are talking with one of your friends about your biology course. He states that the somatic nervous system is subdivided into sympathetic and parasympathetic components, and is responsible for involuntary responses. Is this statement correct?
a) No, although the somatic nervous system controls involuntary responses, it is the autonomic nervous system that is subdivided into parasympathetic and sympathetic components.
b) No, although the somatic nervous system does have both sympathetic and parasympathetic subdivisions, it is responsible for voluntary responses.
c) Yes, this statement is correct. The somatic nervous system has both sympathetic and parasympathetic components and controls involuntary responses.
d) No, the somatic nervous system is responsible for voluntary responses, and is not subdivided into sympathetic and parasympathetic components.

Answer 1

Answer:

The correct answer is option d) "No, the somatic nervous system is responsible for voluntary responses, and is not subdivided into sympathetic and parasympathetic components".

Explanation:

The somatic nervous system is responsible for the control of voluntary body movements via skeletal muscles. Also, the somatic nervous system is not subdivided into sympathetic and parasympathetic components. This subdivision corresponds to the autonomic nervous system, the system that influences the function of internal organs. Therefore the statement of the friend was incorrect.
