Afferent vs. Efferent: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 5, 2023
Afferent refers to the transmission of signals towards a central point, typically in the nervous system, while efferent refers to the conduction of signals away from a central point.

Key Differences

Afferent pathways carry sensory information from the body to the brain. However, efferent pathways convey commands from the brain to the body.

In the context of the nervous system, afferent neurons transmit signals to the central nervous system. Efferent neurons, on the other hand, carry neural impulses away from the central nervous system.

Afferent signals are involved in sensory perception, alerting the brain to external or internal stimuli. Efferent signals are responsible for motor responses and actions.
