The ciliary arteries are divisible into three groups, the long posterior, short posterior, and the anterior. * The short posterior ciliary arteries from six to twelve in number, arise from the ophthalmic as it crosses the optic nerve. * The long posterior ciliary arteries, two for each eye, pierce the posterior part of the sclera at some little distance from the optic nerve. * The anterior ciliary arteries are derived from the muscular branches of the ophthalmic artery. ==Additional images== File:Gray514.png|The ophthalmic artery and its branches File:Gray878.png|Iris, front view.
