The anterior ciliary arteries are seven arteries in each eye-socket that arise from muscular branches of the ophthalmic artery and supply the conjunctiva, sclera, rectus muscles, and the ciliary body. The arteries end by anastomosing with branches of the long posterior ciliary arteries to form the circulus arteriosus major.
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 artery as it crosses the optic nerve .
The globe of the eye, or bulbus oculi, is the frontmost sensory organ of the human ocular system, going from the cornea at the front, to the anterior part of the optic nerve at the back. More simply, the eyeball itself, as well as the ganglion cells in the retina that eventually transmit visual signals through the optic nerve. [ 1 ]
Major arterial circle of the iris" [1] [2] [3] (also: "major circulus arteriosus of iris", [4] or "circulus arteriosus iridis major" [4]) is a circular artery [3] of the eye formed by anastomoses of the anterior ciliary arteries and long posterior ciliary arteries at the ciliary body.
The extraocular muscles are supplied mainly by branches of the ophthalmic artery. This is done either directly or indirectly, as in the lateral rectus muscle, via the lacrimal artery, a main branch of the ophthalmic artery. Additional branches of the ophthalmic artery include the ciliary arteries, which branch into the anterior ciliary arteries ...
Ciliary ganglion with parasympathetic fibers of ciliary nerves. The parasympathetic innervation of the ciliary body is the most clearly understood. Presynaptic parasympathetic signals that originate in the Edinger-Westphal nucleus are carried by cranial nerve III (the oculomotor nerve ) and travel through the ciliary ganglion .
