Afferent

Definition:

Afferent refers to the division of neural pathways that carry signals towards the central nervous system (CNS) from periphery structures or sensory organs.

Key Points:

• Afferent neural pathways transmit sensory information to the CNS.
• The term “afferent” is derived from the Latin word “afferens,” which means “carrying to.”
• In the somatic nervous system, afferent neurons carry sensations such as touch, pain, temperature, and proprioception from the body to the CNS.
• In the autonomic nervous system, afferent neurons provide feedback to the CNS from internal organs and regulate various bodily functions.
• Afferent pathways play an essential role in sensory perception and the overall functioning of the nervous system.
