A sensory nerve is a nerve that carries sensory information toward the central nervous system (CNS). It is an enclosed, cable-like bundle of afferent nerve fibers (the axons of sensory neurons) in the peripheral nervous system (PNS). These fibers link sensory receptors on the body surface or in the tissues to relevant processing circuits in the CNS. Sensory nerves are often paired with motor nerves, which are bundles of efferent nerve fibers that travel from the CNS to the PNS. Stimuli cause nerve impulses in the receptors and alter the potentials, which is known as sensory transduction.
