The ciliary muscle is an intrinsic muscle of the eye formed as a ring of smooth muscle [3] [4] in the eye's middle layer, the uvea (vascular layer). It controls accommodation for viewing objects at varying distances and regulates the flow of aqueous humor into Schlemm's canal .
[1] [2] All of them are smooth muscles. [2] The ciliary muscle is attached to the zonular fibers and the zonular fibers are the suspensory ligaments of the lens. [2] The ciliary muscle controls accommodation by altering the shape of the lens to be able to see an object from near to far. [2]
The ciliary body is a ring-shaped thickening of tissue inside the eye that divides the posterior chamber from the vitreous body. It contains the ciliary muscle, vessels, and fibrous connective tissue. Folds on the inner ciliary epithelium are called ciliary processes, and these secrete aqueous humor into the posterior chamber. The aqueous humor ...
It is secreted from the ciliary body, a structure supporting the lens of the eyeball. [1] It fills both the anterior and the posterior chambers of the eye, and is not to be confused with the vitreous humour, which is located in the space between the lens and the retina, also known as the posterior cavity or vitreous chamber.

The anterior capsule and the zonule form a trampoline shape or hammock shaped surface that is totally reproducible depending on the circular dimensions, i.e. the diameter of the ciliary body (Müeller's muscle). The ciliary body thus directs the shape like the pylons of a suspension bridge, but does not need to support an equatorial traction ...
[10] The human eye is not a plain sphere but is like two spheres combined, a smaller, more sharply curved one and a larger lesser curved sphere. The former, the anterior segment is the front sixth [8] of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens. [6] [11]
Joshua Jefferson (11.5 points per game) and Dishon Jackson (10.9) round out the Cyclones' top five scorers. The nonconference slate has allowed Iowa State coach T.J. Otzelberger to assess some of ...
10. Corneal limbus and 11. Sclera; 12. Conjunctiva, 13. Uvea with 14. Iris, 15. Ciliary body. The anterior segment or anterior cavity [1] is the front third of the eye that includes the structures in front of the vitreous humour: the cornea, iris, ciliary body, and lens. [2] [3] Within the anterior segment are two fluid-filled spaces:
