Which of these statements about the afferent division of the nervous system is true?
A
It primarily controls voluntary muscle movements.
B
It transmits motor commands from the central nervous system to muscles and glands.
C
It is responsible for the fight-or-flight response.

Verified step by step guidance1
Understand the role of the afferent division of the nervous system. The afferent division is responsible for transmitting sensory information from the body to the central nervous system (CNS).
Differentiate between afferent and efferent divisions. The afferent division carries sensory signals to the CNS, while the efferent division carries motor commands from the CNS to muscles and glands.
Recognize that voluntary muscle movements are controlled by the efferent division, specifically the somatic nervous system, not the afferent division.
Identify that the fight-or-flight response is part of the autonomic nervous system, which is a component of the efferent division, not the afferent division.
Conclude that the statement 'It carries sensory information from the body to the central nervous system' accurately describes the function of the afferent division of the nervous system.
