The angular artery is an artery of the face. It is the terminal part of the facial artery. It ascends to the medial angle of the eye's orbit. It is accompanied by the angular vein. It ends by anastomosing with the dorsal nasal branch of the ophthalmic artery. It supplies the lacrimal sac, the orbicularis oculi muscle, and the outer side of the nose.
Structure

It is accompanied by the angular vein. On the cheek, it distributes branches which anastomose with the infraorbital artery.[2] It ends by anastomosing with the dorsal nasal branch of the ophthalmic artery.
