Concept: This question tests your understanding of the functional divisions of the peripheral nervous system, specifically the role of the somatic neural system.

Why (C) is correct: The somatic neural system (SNS) is responsible for transmitting impulses from the central nervous system (CNS) to skeletal muscles. This allows for voluntary control of body movements.

Why other options are wrong:

  • (A) CNS to involuntary organs: This describes the function of the autonomic nervous system (ANS), not the somatic system.
  • (B) Involuntary organs to CNS: This describes afferent (sensory) pathways of the ANS, not the efferent (motor) somatic system.
  • (D) Skeletal muscles to CNS: This describes afferent (sensory) pathways of the somatic nervous system, which carry information from muscles to the CNS, but the question asks what the somatic neural system 'relays impulses from' (implying efferent output).

Common Mistake: Students often confuse the somatic and autonomic nervous systems, especially regarding voluntary vs. involuntary control and their target organs.

NEET Tip / Mnemonic: Remember Somatic = Skeletal muscles = Strong (voluntary) movements. Autonomic = Automatic (involuntary) functions.

Correct Answer: (C)
