Choose the correct answer from the options given below:
A-III, B-IV, C-I D-II
— Concept: This question tests your understanding of the different types of nerve fibres and divisions of the nervous…Concept: This question tests your understanding of the different types of nerve fibres and divisions of the nervous system, specifically their roles in transmitting impulses.
Why (D) is correct:
- (A) Afferent fibres (III): Afferent neurons (sensory neurons) transmit nerve impulses from tissues/organs to the Central Nervous System (CNS). They carry sensory information.
- (B) Efferent fibres (IV): Efferent neurons (motor neurons) transmit regulatory impulses from the CNS to tissues/organs (effectors). They carry motor commands.
- (C) Somatic neural system (I): The Somatic Neural System (SNS) relays impulses from the CNS to skeletal muscles, controlling voluntary movements.
- (D) Autonomic neural system (II): The Autonomic Neural System (ANS) transmits impulses from the CNS to smooth muscles, cardiac muscles, and glands, controlling involuntary functions.
Why other options are wrong:
- A) Incorrect matching for all pairs.
- B) Incorrect matching for B, C, and D.
- C) Incorrect matching for A, B, and C.
NEET Tip / Mnemonic: Remember SAME DAVE: Sensory Afferent, Motor Efferent. Also, Dorsal Afferent, Ventral Efferent (referring to spinal nerves).
Correct Answer: (D)
A-III, B-IV, C-I D-II
