proprioceptor

pro·pri·o·cep·tor

P0604000 (prō′prē-ō-sĕp′tər)n. A sensory receptor, found chiefly in muscles, tendons, joints, and the inner ear, that detects the motion or position of the body or a limb by responding to stimuli arising within the organism.

[Latin proprius, one's own; see per in Indo-European roots + (re)ceptor.]

proprioceptor

(ˌprəʊprɪəˈsɛptə) n (Physiology) physiol any receptor (as in the gut, blood vessels, muscles, etc) that supplies information about the state of the body. Compare exteroceptor, interoceptor[C20: from proprio-, from Latin proprius one's own + receptor] ˌproprioˈceptive adj

pro•pri•o•cep•tor

(ˌproʊ pri əˈsɛp tər)

n. a sensory nerve ending, located in a muscle, tendon, or the inner ear, that provides a sense of the position of the body. [1905–10; < Latin propri(us) one's own + -o- + (re) ceptor]

Translations

Proprioceptor

proprioceptor

[‚prō·prē·ə′sep·tər] (control systems) A device that senses the position of an arm or other computer-controlled articulated mechanism of a robot and provides feedback signals. (physiology) A sense receptor that signals spatial position and movements of the body and its members, as well as muscular tension.

Proprioceptor

a specialized sensory nerve terminal that is located in the musculoskeletal system, which includes skeletal muscles, tendons, and ligaments. Proprioceptors react to the contraction and tension or the relaxation and stretching of muscles. They belong to the group of mechanoreceptors.

In addition to free nerve terminals, proprioceptors include the following: muscle spindles, which consist of several thin and intrafusal muscle fibers entwined by spiral-like nerve terminals; Golgi’s corpuscles, which are found in tendons; and Pacini’s corpuscles, which are concentrated in the fascia, tendons, and ligaments. The extent to which a spindle contracts is regulated by the gamma motor system (gamma efferent nerve fibers)—processes of special motor neurons of the spinal cord. Muscle spindles are excited by a lengthening of fibers, while Golgi’s corpuscles, or tendon organs, are excited by the contraction of fibers. Impulses from spindles that reach the central nervous system facilitate the contraction of a particular muscle and inhibit the contraction of its antagonist. Impulses from tendon proprioceptors exert the opposite effect. Signals on the movement of body parts originate in proprioceptors; these signals are the main regulators of information that arrives from other sensory organs.

proprioceptor

[pro″pre-o-sep´tor] any of the sensory nerve endings that give information concerning movements and position of the body; they occur chiefly in muscles, tendons, and the labyrinth. adj., adj propriocep´tive.

pro·pri·o·cep·tor

(prō'prē-ō-sep'tŏr), One of a variety of sensory end organs (such as the muscle spindle and Golgi tendon organ) in muscles, tendons, and joint capsules that sense position or state of contraction.

proprioceptor

(prō′prē-ō-sĕp′tər)n. A sensory receptor, found chiefly in muscles, tendons, joints, and the inner ear, that detects the motion or position of the body or a limb by responding to stimuli arising within the organism.

pro′pri·o·cep′tive adj.

proprioceptor

A sensory end organ that provides information about the position of the body and its parts in space at a particular moment in time; proprioceptors are present in muscle, tendons and joint capsules, and include the muscle spindle and the Golgi tendon organ.
