mechanoreceptor Physiol.|ˌmɛkənəʊrɪˈsɛptə(r)|
Also mechano-receptor.
[f. mechano- + receptor.]
A sensory receptor which responds to mechanical stimuli, such as pressure changes resulting from touch or sound.
1927J. H. Parsons Introd. Theory Perception i. 7 Receptors which are found in animals may be classified into three groups..chemo-receptors, mechano-receptors, and radio-receptors. Ibid. 9 Mechano-receptors can be divided into two classes, contact and distance receptors. 1951Sci. Amer. Jan. 17/2 Among these mechano-receptors are the receptor organs for rotatory and translatory motion in the inner ear, the receptors responsible for the pressure sense of the skin, the muscle spindles imbedded in all muscles that fix and move bodily masses, and the so-called Pacinian or Vater's corpuscles found throughout the connective tissues. 1970Nature 28 Mar. 1263/2 These passive movements are perceived by mechanoreceptors of the pedicel.
Hence ˌmechanoreˈception, the process by which a mechanical stimulus is converted by a mechanoreceptor into a nervous impulse; ˌmechanoreˈceptive a., capable of performing mechanoreception.
1951Jrnl. Physiol. CXV. 16 The mechanoreceptive area was localized by touching the tongue with a thin wire while listening to the pressure impulses in the loudspeaker. 1958Jrnl. Gen. Physiol.

Kenshalo Skin Senses vii. 139 (heading) A duplex mechanism of mechanoreception. 1974Nature 26 Apr. 740/2 Neuromas in man must..contain mechano⁓receptive endings since they are always tender when gently palpated. |
