The neurons lose both myelin and neurilemmalsheaths prior to termination. It demonstrates free nerve endings with expanded tips contacting specialized epidermal cells. The nerve fiber loses myelin near sebaceous glands and encircles the outer root sheath of the hair follicle. Flattened connective tissue forms horizontal lamellae which surround a naked axon. The corpuscle is linked by filaments to overlying epidermis.
Pacinian corpuscle is sensory to pressure and vibration.
Flat epitheliod cells form lamellae around the axon terminal. The capsule is continuous with the perimysium of muscle. Within the fluid-filled capsule are intrafusal muscle fibers. The central region of these fibers is filled with nuclei and is oncontractile. This region is contacted by afferent nerve endings.
