Baroreceptor Reflexes - P. B. Persson - książka wyd. 1991

Opis

The term ‘arterial baroreceptor reflex’ is used to refer to a variety of physiological responses elicited by changes in baroreceptor afferent activity. While the baroreceptor reflex is often used in specific reference to the reflexive change in ABP and heart rate brought about by changing autonomic outflow to the heart and vasculature, there are a large number of physiological responses resulting from changes in baroreceptor afferent input, and they would each appropriately be termed a baroreceptor reflex. For example, decreases in ABP sensed by arterial baroreceptors elicit an increase in vasopressin (antidiuretic hormone) secretion from the posterior pituitary and an increase in thirst (as reflected by increased fluid ingestion). Thus, baroreceptor reflexes can be viewed as having autonomic, endocrine, and behavioral effectors, all of which interact to promote cardiovascular homeostasis (Figure 2).
