The peripheral neural system is divided into two parts; these parts are called the somatic neural system and ________.

Correct option is D

Ans. (d)
Sol. The peripheral nervous system (PNS) is divided into two main parts: the somatic nervous system (SNS) and the autonomic nervous system (ANS).
· The somatic nervous system controls voluntary movements by transmitting signals from the central nervous system (CNS) to skeletal muscles.
· The autonomic nervous system regulates involuntary functions, such as heart rate, digestion, and respiration, by controlling smooth muscles and glands.
Explanation of each option:
· (a) The spinal neural system – Incorrect, as the spinal cord is part of the central nervous system (CNS), not the peripheral nervous system.
· (b) The visceral nervous system – Incorrect, as "visceral" refers to organs, but the proper classification is the autonomic nervous system.
· (c) The sympathetic neural system – Incorrect, as the sympathetic system is a subdivision of the autonomic nervous system (ANS), not a separate division of the PNS.
· (d) The autonomic neural system – Correct answer. The PNS is divided into the somatic nervous system (voluntary control) and the autonomic nervous system (involuntary control).
