Sensory Functions

The skin is our most extensive sense organ. It is equipped with a variety of nerve endings that react to heat, cold, touch, texture, pressure, vibration, and tissue injury. These sensory receptors are especially abundant on the face, palms, fingers, soles, nipples, and genitals. There are relatively few on the back and in skin overlying joints such as the knees and elbows. Some receptors are naked dendrites that penetrate into the epidermis. Most, however, are limited to the dermis and hypodermis. The individual types of cutaneous receptors are described in chapter 16.
