Which Reflex is Concerned with the Regulation of Blood Pressure

Question

Which reflex is concerned with the regulation of blood pressure?
A) Achilles' tendon
B) Babinski
C) Patellar
D) Baroreceptor

Accepted Answer

The Baroreceptor reflex is concerned with regulating blood pressure. Baroreceptors are specialized nerve cells located in the walls of certain blood vessels, primarily in the carotid sinus and aortic arch. These receptors sense changes in blood pressure and send signals to the brainstem to adjust heart rate, vascular resistance, and cardiac output in order to maintain blood pressure within a narrow range. The other choices (Achilles' tendon, Babinski, and Patellar reflexes) are not directly related to blood pressure regulation.
