Stretch receptor

Stretch receptors are mechanoreceptors responsive to distention of various organs and muscles, and are neurologically linked to the medulla in the brain stem via afferent nerve fibers.^{[citation needed]} Examples include stretch receptors in the arm and leg muscles and tendons, in the heart, in the colon wall, and in the lungs.^{[citation needed]}

Stretch receptors are also found around the carotid artery, where they monitor blood pressure and stimulate the release of antidiuretic hormone (ADH) from the posterior pituitary gland.^[1]

Types include:

Golgi organ^[2]
Muscle spindle, sensory receptors within the belly of a muscle, which primarily detect changes in the length of this muscle^[3]
Pulmonary stretch receptors, mechanoreceptors found in the lungs^[4]
Chordotonal organ, in insects and crustaceans^[5]
