(anatomy) One of two arteries supplying the thyroid gland and nearby structures at the front of the neck that branches from the external carotid artery or sometimes from the common carotid artery at the level of the thyrohyal of the hyoid bone and that gives off branches to nearby muscles and to the thyroid gland.

(anatomy) A branch of the superior thyroid artery or sometimes of the external carotid artery that supplies the muscles, mucous membranes, and glands of the larynx and anastomoses with the branch from the opposite side.

(anatomy) Either of two branches of the facial artery of which one is distributed to the upper and one to the lower lip.

(anatomy) A branch or continuation of the maxillary artery that runs along the infraorbital groove with the infraorbital nerve and passes through the infraorbital foramen to give off branches which supply the face just below the eye.

(anatomy) A large branch of the ophthalmic artery that arises near the optic foramen, passes along the superior border of the lateral rectus, and supplies the lacrimal gland.

(anatomy) Any of several arteries that arise from the ophthalmic artery or its branches and supply various parts of the eye.

(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.
