proprioception
biology
Also known as: balance, equilibrium
proprioception, the perception by an animal of stimuli relating to its own position, posture, equilibrium, or internal condition. The coordination of movements requires continuous awareness of the position of each limb. The receptors in the skeletal (striated) muscles and on the surfaces of tendons of vertebrates provide constant information on the positions of limbs and the action of muscles. Comparable organs of arthropods (e.g., insects, crustaceans) include stretch receptors located on the outsides of muscles and chordotonal organs (special nerves that measure tension changes) within the joints. Awareness of limb position and movements is also gained through the stimulation of ...(100 of 330 words)
