Afferent Neurons send information in which direction?

• A. Toward the central nervous system
• B. Toward the muscles
• C. Within the same neuron
• D. Across the synaptic gap

Answer: (A)

Afferent neurons carry sensory information from receptors in the body toward the central nervous system. The term afferent reflects this direction, meaning “toward” the brain or spinal cord. This is in contrast to efferent neurons, which transmit commands from the CNS to muscles and glands. So the best description of the path is signals traveling toward the central nervous system, such as from the skin or internal organs, to be processed by the brain and spinal cord.
