1. Irritant and stretch receptors in the lungs can directly cause exhalation. 2. Stretch receptors cause postganglionic neurons to release norepinephrine ( NE ).3. The tendon organ is a stretch receptor that signals the force developed by the muscle. 4. In the right atrium, the stretch receptors occur at the junction of the venae cavae. 5. The apneustic center is inhibited by pulmonary stretch receptors . 6. The volume of water in the body is measured by stretch receptors in the hypo-osmolar conditions. 7. It is initiated either by stimulation of stretch receptors or stimulation of proprioceptors activated by lung deflation. 8. Sulfur dioxide blocks nerve signals from the pulmonary stretch receptors and abolishes the Hering Breuer inflation reflex. 9. Arterial baroreceptors are stretch receptors that are stimulated by distortion of the arterial wall when pressure changes. 10. The spindle is a stretch receptor with its own motor supply consisting of several intrafusal muscle fibres.
