In the peripheral nervous system, afferent fibres are so named because they:
ACarry motor commands away from the central system
BConnect the two hemispheres of the brain together
CCarry sensory information toward the central system
DRegulate the glands of the endocrine system directly
Answer & Solution
Correct answer: C. Carry sensory information toward the central system
1. The somatic nervous system relays sensory and motor information to and from the central nervous system.
2. Afferent fibres are the sensory neurons, and afferent means moving toward, so they carry information toward the central nervous system.
3. Efferent fibres are the motor neurons, and efferent means moving away from, carrying instructions out to the muscles.
4. Each nerve is described as a two-way superhighway containing thousands of both kinds of axon.
