n.
a group of cells that respond to mechanical distortion, such as that caused by stretching or compressing a tissue, by generating a nerve impulse in a sensory nerve (see receptor). Touch receptors, proprioceptor, and the receptors for hearing and balance all belong to this class.

mech·a·no·re·cep·tor (mek″ə-no-re-sepґtər) a receptor that is excited by mechanical pressures or distortions, as those responding to sound, touch, and muscular contractions.
