What is the internal and external carotid arteries?

The carotid arteries are major blood vessels in the neck that supply blood to the brain, neck, and face. The internal carotid artery supplies blood to the brain. The external carotid artery supplies blood to the face and neck.

What is internal carotid artery?

The internal carotid arteries are branches of the common carotid arteries that bifurcate into the internal and external carotids at the level of the carotid sinus. [2] After this bifurcation, the internal carotids traverse through the base of the skull to reach the vital organs that they supply.

What is the first branch of the internal carotid artery?

ophthalmic artery
The first major branch of the ICA, the ophthalmic artery, arises at the level of the anterior clinoid process (Fig. 22‐3). After initially running intracranially, this artery traverses the optic canal and then goes to the orbit.
