Carotid bifurcation

Dr Jeremy Jones et al.

The carotid bifurcation is the point at which the the common carotid artery terminates. As it does so, it forms the internal and external carotid arteries which go on to supply the head and neck.

It is closely related anatomically to the carotid body, a small group of chemoreceptors and supporting matrix that reacts to the change in composition of the blood flowing through the bifurcation.
