Sensory Cutaneous Nerve Endings
There are at least eight major types of sensory nerve endings involved in general sensation: free nerve endings, Merkel discs, hair follicle receptors, lamellated Pacinian corpuscles, tactile Meissner's corpuscles, Ruffini's corpuscles, Golgi tendon organs, and muscle spindles. Many of these nerve endings are associated with the skin; others are associated with deeper structures, such as tendons, ligaments, and muscles; and some can be found in both the skin and deeper structures.
