Touch, also called tactition, mechanoreception or somatic sensation, is the sense of pressure perception, generally in the skin. There are a variety of nerve endings that respond to variations in pressure (e.g., firm, brushing, and sustained). Paresthesia is a sensation of tingling, pricking, or numbness of a person's skin with no apparent long term physical effect.

The inability to feel anything or almost anything is called anesthesia.
