X 80. The Ciliary Body.—The ciliary body (corpus ciliare), the middle portion ofthe vascular tunic, extends from the ora serrata to the sclero-corneal through the eyeball in a meridional direction (Fig. 1214) show that it hasa triangular form. The outer side is in apposition to the sclera, the inner is coveredby the pigmented extension of the retina, and the short anterior side, at right anglesto the outer, extends inward from the pectinate ligament toward the lens. The ciliary body presents three subdivisions ; the ciliary ring, the ciliajy pro-cesses and the ciliary viuscle. Cornea Fig. 1214.

The ciliary ring, or orbicidns ciliaris, consists of a smooth band of tissue, 4mm. in width, in advance of the ora serrata. It differs in structure from the choroidin the absence of the choriocapillaris, its vessels running in a longitudinal directionand returning the blood from the iris and ciliary body to the venae vorticosse. Onits inner surface, delicate meridionally placed folds make their appearance, by theunion of which the ciliarv processes are formed. The ciliary processes constitute the remainder of the inner portion of theciliary body. They form an annular series of folds, about seventy in number, whichsurround the lens and act as points of attachment to its suspensory ligament. 92 1458 HUMAN ANATOMY.
