It appears that in diving the decrease in pulmonary stretch receptor activity during apnea, combined with cessation of central inspiratory neuronal drive, is an important ... WebType A receptors and Type B receptors are both within the atria of the heart. Type A receptors are activated by wall tension, which develops by atrial contraction during ventricular diastole. Type B receptors are activated by wall stretch, which develops by atrial filling during ventricular systole. [1]

WebDuring inspiration, the lung's stretch receptors become active. They communicate sensory data to the nucleus tracts solitarius. This nucleus then sends unclear information to another nucleus. With the stimulation of the nucleus ambiguous, the vagal nerve is inhibited. The vagal nerve is the heart's parasympathetic nerve. WebAn example of a receptor is a stretch receptor found in the muscles which detects changes in length or tension and sends signals to the brain which then triggers a response that helps to maintain homeostasis. ... The medulla oblongata is responsible for regulating the heart rate and other involuntary body functions, such as breathing, through ...
WebOther articles where stretch receptor is discussed: muscle: Whole muscle: …has important sensory structures called stretch receptors, which monitor the state of the muscle and return the information to the central nervous system. Stretch receptors are sensitive to the velocity of the movement of the muscle and the change in length of the muscle. They … WebStretch receptors are situated in the walls of the atria, left ventricle and coronary arteries. Atrial receptors are stimulated by atrial distension due to increased filling as the result, amongst other things, of an increased blood volume. Their reflex responses are increases in heart rate and in urine flow.
Arterial baroreceptors are stretch receptors that are stimulated by distortion of the arterial wall when pressure changes. The baroreceptors can identify the changes in both the average blood pressure or the rate of change in pressure with each arterial pulse. Action potentials triggered in the baroreceptor ending are then directly conducted to the brainstem where central terminations (synapses) transmit this information to neurons within the solitary nucleus which lies in the medu… 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 …
