Question

Quizplus · Accepted Answer

Baroreceptors are specialized nerve endings located in the carotid sinus (in the neck) and aortic arch (in the chest). They are activated when there is a change in blood pressure, either a sudden increase or decrease. They play an important role in regulating blood pressure by signaling the brain to adjust heart rate and blood vessel diameter. Baroreceptor activation is not a response to pedal edema, which is a buildup of fluid in the lower extremities due to various causes.
