摘要: Whiskers are highly sensitive touch organs in all mammals apart from man. A blood sinus encloses the hair follicles completely or almost completely. One has several thousand sensory nerve endings. Most of them located epithelial thickening below sebaceous gland. large number Merkel cells with associated endings can be found that region. The absolute depends on species and size hair. In cat rat, whiskers have up to 2000 cell-nerve innervated by approximately 100 myelinated axons.
