The long posterior ciliary arteries (arteria? ciliaresposteriores longie), two in number—one on the nasal side and one onthe temporal side—are of large calibre. They run forward in theperichoroidal space to the front of the eyeball, without giving off anyintermediate branches, supply the ciliary muscle and terminate inthe arterial circles of the iris, anastomosing with the anterior ciliaryarteries. The central artery of the retina {arteria centralis retinae) is oneof the smallest branches of the ophthalmic. It arises near the origin 408 ANATOMY (GROSS) OF THE HUMAN EYE of the branches just described, and pierces the optic nerve obliquelyabout 20 mm. from the sclera. Upon entering the eyeball through theoptic disc it is distributed over the retina as previously Horizontal Section of Orbit. a. Tarsus. b. Orbicularis. c. Muscle of Horner. d.
