What are the different ways, physiological and pharmacological, in
which blood vessel diameter can be modified?
Detection of changes in blood pressure (leading to resultant changes in blood vessel diameter):
Baroreceptors at the carotid sinus (the bifurcation of internal and external carotid arteries in the neck) and the aortic arch detect changes in blood pressure. These non-encapsulated nerve endings, located in the adventitial layer of arteries, are technically mechanoreceptors; they respond to arterial distension occurring due to a change in blood pressure. …
