(anatomy) Either of usually two arteries of which one arises from the ophthalmic artery on each side of the optic nerve, passes forward along the optic nerve accompanying the short posterior ciliary arteries, pierces the sclera passing forward on the same side of the eyeball between the sclera and the choroid to the ciliary muscle, and at the junction of the ciliary process and the iris divides into upper and lower branches which anastomose with the branches of the contralateral artery to form a ring of arteries around the iris.

(anatomy) Any of 6 to 10 arteries that arise from the ophthalmic artery or its branches, pass to the posterior part of the eyeball while surrounding the optic nerve, and enter or divide into branches entering the sclera to supply the choroid and the ciliary processes.

(anatomy) A branch of the internal carotid artery following the optic nerve through the optic foramen into the orbit and supplying the eye and adjacent structures.

(anatomy) A branch of the inferior alveolar artery on each side that emerges from the mental foramen and supplies blood to the chin.

(anatomy) An artery that arises from the external carotid artery opposite to the origin of the facial artery, that passes posteriorly to the base of the skull where it turns upward and ascends within the superficial fascia of the scalp, and that supplies or gives off branches supplying structures and especially muscles of the back of the neck and head.

(anatomy) A branch of the thyrocervical trunk that passes obliquely from within outward and over the suprascapular ligament to the back of the scapula.
