Receptor cell

Nerve fibre


The sense of touch includes sensations such as pain, pressure, vibration, and temperature. These sensations are detected by two types of receptor under the surface of the skin: free (uncovered) nerve endings, and enclosed nerve endings called corpuscles. Different types of nerve ending or corpuscle monitor particular sensations. The number of receptors varies around the body: for example, the fingertips are highly sensitive and have many receptors, whereas the middle of the back has fewer receptors.
