whar are sensory afferent nerves main funtion
(April 2014). In the peripheral nervous system, an afferent nerve fiber is the nerve fiber (axon) of an afferent neuron (sensory neuron). It is a long process (projection) extending far from the nerve cell body that carries nerve impulses from sensory receptors or sense organs toward the central nervous system.The opposite direction of neural activity is efferent conduction.In the nervous system there is a closed loop system of sensation, decision, and reactions. This process is carried out through the activity of afferent neurons (sensory neurons), interneurons, and efferent neurons (motor neurons).t is a long process (projection) extending far from the nerve cell body that carries nerve impulses from sensory receptors or sense organs toward the central nervous system. The opposite direction of neural activity is efferent conduction.
From Wikipedia, the free encyclopedia. Sensory neurons are nerve cells that transmit sensory information (sight, sound, feeling, etc.). They are activated by sensory input, and send projections to other elements of the nervous system, ultimately conveying sensory information to the brain or spinal cord.hey are activated by sensory input, and send projections to other elements of the nervous system, ultimately conveying sensory information to the brain or spinal cord.
