GlossaryVibrissa Follicles

specialized hair follicles producing sensitive whiskers in mammals

Vibrissa follicles, also known as whisker follicles, are specialized hair follicles found in mammals that produce long, stiff hairs called vibrissae or whiskers. These follicles are highly innervated, meaning they have a rich supply of nerve endings, which makes them extremely sensitive to touch and helps animals detect their surroundings, navigate in the dark, and sense nearby objects.
