Stretch receptors in heart
WebHome AHA/ASA Journals WebCardiac receptors include both mechanically and chemically sensitive receptors located in atria and in ventricles. Atrial receptors innervated by myelinated vagal afferent fibers reflexly regulate heart rate and intravascular volume. On the other hand, stimulation of ventricular receptors can cause either reflex bradycardia and hypotension or ...
Stretch receptors in heart
Did you know?
WebThe receptors are located in the atria, ventricles, and pulmonary vessels. The atria contain two types of receptors: those activated by the tension developed during atrial contraction (A receptors) and those activated by the stretch of the atria during atrial filling (B receptors). Stimulation of these atrial receptors sends impulses up vagal ...

We show that a physiological role of stretch-induced NOX2-derived ROS is to contribute to the Frank-Starling law of the heart, … WebOct 27, 2024 · Special pressure sensors called baroreceptors (or venoatrial stretch receptors) located in the right atrium of the heart detect increases in the volume and pressure of blood returned to the heart. These receptors transmit information along the vagus nerve (10th cranial nerve) to the central nervous system.
WebThe pulmonary stretch receptors are nerves ending in the tracheal and bronchial smooth muscles. Their activity is enhanced by enlargement of airway cross-section, for example, when the lung volume increases, and results in an inhibition of further inspiratory activity. WebSimilarly, baroreceptors are stretch receptors located in the aortic sinus, carotid bodies, the venae cavae, and other locations, including pulmonary vessels and the right side of the heart itself. Rates of firing from the baroreceptors represent blood pressure, level of physical activity, and the relative distribution of blood.
