what does it mean for a sensory pathway to be afferent
Afferent nerve fiber In the peripheral nervous system (PNS), an afferent nerve fiber is the axon of a sensory neuron. It is a long process extending far from the nerve cell body that carries an action potential from the sensory neuron toward the central nervous system (CNS). Bundles of these axons form a nerve known as an afferent nerve, or sensory nerve.
