Related to stretch receptors: Baroreceptors, pressure receptors

stretch re·cep·tors

receptors that are sensitive to elongation, especially those in Golgi tendon organs and muscle spindles, but also those found in visceral organs such as the stomach, small intestine, and urinary bladder; these receptors have the function of detecting elongation, and this distinguishes them from baroreceptors, which actually are activated by stretching of the wall of the blood vessel but the function of the stretch receptors is to elicit the central reflex mechanism reducing the arterial blood pressure.

stretch receptors,

n.pl the specialized sensory nerve endings in muscle spindles and tendons that are stimulated by stretching movements. They are active in maintaining dynamic posture.

In normal breathing after a particular degree of stretching or even before this, stretch receptors (situated in the walls of the alveoli) are stimulated and send information to the respiratory center so that exhalation sets in.
The stretch receptors are thus trained to withstand more and more stretching which helps to hold the breath for a long period.

In our present study both PEFR & BHT were increased significantly because stimulation of the pulmonary stretch receptors due to maximum inflation of the lung during deep breathing reflexly relaxes the smooth muscles of tracheo bronchial tree.
From these biomechanical results, we conclude that the lateral flagellum could measure water motion with two different types of sensors: external flow detectors that would analyze relative water flow over the flagellar surface, and intersegmental stretch receptors that would measure flagellar bending.
