Vibrissa

There are also long hairs inside each ear and sometimes on its tip, and about a dozen very long and strong hairs—the whiskers or vibrissæ— are placed on each upper lip.

The vibrissae are coarse hairs whose follicles are located just within the nasal meatus. […] Vibrissae are present in most mammals, but their innervation and role in sensory function appears to be less pronounced in humans.
