Describe the bainbridge reflex
WebThe withdrawal reflex (nociceptive flexion reflex or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli. The reflex rapidly coordinates the contractions of all the flexor muscles and the relaxations of the extensors in that limb causing sudden withdrawal from the potentially damaging stimulus. Spinal reflexes are … WebThe Bainbridge reflex is invoked throughout the anesthesia literature to describe the effect of changes in venous return on heart rate in patients in the surgical and critical care settings, but a critical analysis of the experimental and clinical evidence is lacking. Our main objectives in this review are to summarize the history of the ...

WebThe Bainbridge reflex also provides a degree of redundancy to the baroreceptor reflex by facilitating tachycardia during inspiration. The Bezold-Jarisch reflex, which may contribute to dysrhythmia following, for example, ischemic damage to the ventricles, may also have an adaptive role in dampening the sympathetic response to orthostatic ... WebBainbridge reflex, also called atrial reflex, acceleration of the heart rate resulting from increased blood pressure in, or increased distension of, the large systemic veins and the right upper chamber of the heart. This reflex, first described by the British physiologist Francis Arthur Bainbridge in 1915, prevents the pooling of blood in the ...
WebAug 1, 2002 · the importance of the baroreceptor reflex is to stabilize perfusion pressure in the face of disturbances of circulatory homeostasis. This is achieved by a number of neuronal (8, 29, 37, 48) and humoral (37, 45, 46) regulatory adjustments.These adjustments are initiated by a change in the pressure load at specialized pressure sensors located at … WebDescribe the cardiac response to variations in blood flow and pressure; The autorhythmicity inherent in cardiac cells keeps the heart beating at a regular pace; however, the heart is regulated by and responds to outside influences as well. ...
