Ion channels are situated near these networks. The afferent nerve endings that sense stimuli originating from outside of the body, such as touch, vibration, pain, vision, and sound, are called exteroceptors. Meissners and Pacinian corpuscle end-organsĪδ fibers (Nociceptors of neospinothalamic tract)Ĭ fibers (Nociceptors of paleospinothalamic tract)Ĭutaneous receptors are at the ends of afferent neurons. Slowly adapting cutaneous mechanoreceptors ( Merkel and Ruffini corpuscle end-organsĪβ fibers (Merkel and Ruffini's), Aδ fibers (free nerve endings) Proprioception comes from sensory nerve endings that provide our brain with the information of the limb position.

#Examples of nerve endings skin
The modalities and their receptors are partly overlapping, and are innervated by different kinds of fiber types. The pain and temperature receptors in the dermis of the skin are examples of neurons that have free nerve endings. Lamellar Corpuscles: deep pressure, tickle, itch and vibration. With the above-mentioned receptor types the skin can sense the modalities touch, pressure, vibration, temperature and pain. Correctly match each type of sensation with the type of nerve ending it stimulates. Merkel's disc (sustained touch and pressure).Pacinian corpuscle (deep pressure, fast vibrations).
Meissner's corpuscle (changes in texture, slow vibrations).
Cutaneous receptors include mechanoreceptors (pressure or distortion), nociceptors (pain), and thermoreceptors (temperature). They are a part of the somatosensory system. noun C usually plural us / nv en.d / uk / nv en. A cutaneous receptor is the type of sensory receptor found in the skin ( the dermis or epidermis).
