Paciniform endings
WebThese are the Pacinian corpuscles (PC), which are the largest mechanoreceptors in the body, Meissner corpuscles, Merkel cell neurite processes and paciniform endings (formerly Ruffini endings). A fifth type of neural process found in skin is the free nerve endings, which has no organized end-organ structure. WebNov 30, 2016 · Paciniform corpuscles are small cylindrical encapsulations that ensheathe the end of a sensory nerve. In muscle, because they are located near contracting fibers, they may be signaling changes in muscle length. Free Nerve Endings Free nerve endings are distributed widely throughout all types of muscle and connective tissue.
