Second, peripheral nerve endings stimulate neighboring afferent nerve fibers in the dermis and epidermis, a process known as “axon reflex.” Stimulated release of neuropeptides results in vascular responses (“triple response of Lewis,” erythema by ... WebPeripheral Sensory Nerve Endings. Peripheral nerve receptors can be divided into several categories: Mechanoreceptors: mechanical deformation of the receptor gives the sense of touch, including pressure and vibration. Proprioceptors: mechanical deformation of the receptor located in a joint capsule, tendon, or muscle gives a sense of movement.
