Covers the internal carotid artery, which ascends through the neck, enters the skull via the carotid canal, and supplies the brain and eyes. A table lists its main branches with their supply areas, including the ophthalmic, posterior communicating, anterior choroidal, anterior cerebral and middle cerebral arteries. It then gives a separate breakdown of the ophthalmic artery's origin, course through the optic canal and its branches.

COMMON CAROTID ARTERY
1 Common carotid artery (arteria carotis communis)
– ascends along the trachea
– bifurcates within the carotid triangle at the level of C4
– passes dorsolaterally giving off no branches within the neck
– enters the cranium to give off branches supplying the brain and eyeball
The common carotid artery is a major blood vessel that plays a crucial role in supplying oxygenated blood to the head and neck. There are two common carotid arteries in the human body, one on the right side and one on the left sid
INTERNAL CAROTID ARTERY
O: Ascends along the neck and enters the base of the skull through the carotid canal.
S: Supplies blood to the brain and eyes
Branches :
* Terminal branches
OPHTHALMIC ARTERY
O: Originate from internal carotid art.
Enters the orbit through the optic canal, running alongside the optic nerve.
Branches (10) OR MECLESSI
terminal branches
