The PNS is divided into two subdivisions: the somatic nervous system and the autonomic nervous system. C. The PNS controls voluntary movements of skeletal muscles and provides sensory feedback from the skin, joints, and muscles. D. The PNS regulates involuntary functions of smooth muscles, cardiac muscles, and glands.

Correct Answer is D

Explanation

Choice A reason:

This is a correct statement, as the PNS consists of cranial and spinal nerves that connect the CNS to the rest of the body and transmit sensory and motor signals.

Choice B reason:

This is a correct statement, as the PNS is divided into two subdivisions: the somatic nervous system (SNS) and the autonomic nervous system (ANS).

Choice C reason:

This is a correct statement, as the PNS controls voluntary movements of skeletal muscles and provides sensory feedback from the skin, joints, and muscles through the SNS.

Choice D reason:

This is an incorrect statement, as this is the function of the ANS, which is a subdivision of the PNS. The ANS regulates involuntary functions of smooth muscles, cardiac muscles, and glands through its two branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).
