Proprioception (/ˌproʊprioʊˈsɛpʃən, -priə-/[1][2] PRO-pree-o-SEP-shən), from Latin proprius, meaning "one's own", "individual", and capiocapere, to take or grasp, is the sense of the relative position of one's own parts of the body and strength of effort being employed in movement.[3]

In humans, it is provided by proprioceptors (muscle spindles) in skeletal striated muscles and tendons (Golgi tendon organ) and the fibrous capsules in joints. It is distinguished from exteroception, by which one perceives the outside world, and interoception, by which one perceives pain, hunger, etc., and the movement of internal organs.

The brain integrates information from proprioception and from the vestibular system into its overall sense of body position, movement, and acceleration. The word kinesthesia or kinæsthesia (kinesthetic sense) strictly means movement sense, but has been used inconsistently to refer either to proprioception alone or to the brain's integration of proprioceptive and vestibular inputs.
