Arteries of the Neck and Head

ARTERIES OF THE NECK AND HEAD ANATOMY

The blood supply to the neck is the responsibility of the common carotid artery. Directed upward along the lateral side, this artery parallels the trachea.

Internal and external carotid arteries are found along the various branches which can be traced along the angle of the mandible.

The arteries here are close enough to the surface of the skin that the pulsations of the heart can be felt by pressing gently along these arteries.

ARTERIES OF THE NECK AND HEAD FUNCTIONS

The carotid sinus is the mild dilation that can be located at the base of the carotid artery. Within the carotid sinus there are baroreceptors which are responsible for detecting changes in blood pressure.

The carotid bodies encompass the carotid sinus and respond to the chemically based changes within the blood via tiny neurovascular organs which hold chemoreceptors.
