Which term describes signals that travel away from the central nervous system?

• A. Afferent
• B. Efferent
• C. Sensory
• D. Motor

Answer: (B)

Direction of neural signaling is what this item is testing: signals that leave the central nervous system are efferent. Efferent neurons carry commands from the brain or spinal cord to effectors such as muscles, glands, or other organs, producing actions like muscle contraction or gland secretion. Afferent signals travel toward the CNS and convey sensory information from the body to the brain. While motor describes the action produced by these signals and is a type of efferent pathway, the term that specifically denotes outward flow from the CNS is efferent.
