Afferent nerve fibers

Definition:
Sensory neurons that carry messages inward to the central nervous system from the cells in the periphery of the body.
 
Background:
The cell bodies of almost every axon that bring sensory information into the brain and spinal cord are located outside the central nervous system. Afferent means "coming into or toward a structure" and afferent nerve fibers carry sensory information from the periphery toward the CNS.
