proprioceptor Physiol.|ˈprəʊprɪəʊsɛptə(r)|
[f. L. propri-us own, proper + -o + receptor.]
Any sensory structure which receives stimuli arising within the tissues (other, usually, than the viscera); esp. one concerned with the sense of position and movement of a part of the body. Cf. exteroceptor, interoceptor.
1906[see exteroceptor]. 1927Haldane & Huxley Animal Biol. i. 24 The receptor organs are those parts of the living organism which are specially sensitive to the changes going on around them. Some of them are affected by the changes going on inside the body in muscles and joints and in the organ of balance (proprioceptors), others by the changes taking place in the world outside (exteroceptors). 1938Jrnl. Exper. Biol. XV. 112 The campaniform sensilla will act as proprioceptors for the palps. 1940Fraenkel & Gunn Orientation of Animals iv. 37 In the knee-jerk the stimulus is translated by the proprioceptors in the leg, goes to the central nervous system and is there, so to say, reflected back to the leg, where it is translated into effect or action. 1964J. Z. Young Model of Brain xv. 242 Proprioceptors are probably present [in octopus arms] but it is not clear how they could appropriately signal the position of the arms. 1974D. & M. Webster Compar. Vertebr. Morphol. x. 200 The most studied proprioceptor is the muscle spindle.
So proprioˈception, the reception of information by proprioceptors and its interpretation; proprioˈceptive a.; proprioˈceptively adv. (rare).
1906C. S. Sherrington Integrative Action of Nervous Syst. iv. 130 Since in this field the stimuli to the receptors are given by the organism itself, their field may be called the proprio-ceptive field. Ibid. ix. 349 The supposition that the organ [sc. the cerebellum] is the chief co-ordinative centre or rather group of centres of the reflex system of proprio-ception. 1927Haldane & Huxley Animal Biol. v. 123 Proprioceptive organs may affect the consciousness. Thus we can tell how much our knee is bent even with our eyes shut, owing to the joint-organs, or how great a weight we are holding, owing to the muscle-organs. 1958S. H. Bartley Princ. Perception xiv. 315 Kinesthesis and the vestibular sense have been called proprioception, since they have something to do with end results originated by the activity of the body itself. 1961L. F. Brosnahan Sounds of Language i. 15 Articulations which are similar..must require greater precision of execution..in order to keep the resulting speech sounds distinct, both proprioceptively and auditorily. 1968New Scientist 7 Nov. 315/1 Proprioceptive information..describes such things as the tension in the muscles and the location and movement of the parts of the limb. 1977Lancet 5 Nov. 977/1 He had..absent vibration sense, and very reduced proprioception in the lower limbs. |
