The lens is located towards the front part of the vertebrate eye, called the anterior segment, which includes the cornea and iris positioned in front of the lens. The lens is held in place by the suspensory ligaments (Zonule of Zinn), [1] attaching the lens at its equator to the rest of the eye [2] [3] through the ciliary body.
The lens is suspended to the ciliary body by the suspensory ligament (zonule of Zinn), made up of hundreds of fine transparent fibers which transmit muscular forces to change the shape of the lens for accommodation (focusing). The vitreous body is a clear substance composed of water and proteins, which give it a jelly-like and sticky composition.
Sheep eye lens capsule with ligaments attached. The capsule is lifting off the lens showing cell fiber ends beneath. Microscope image of lens capsule in relation to lens cell types. The lens capsule is a component of the globe of the eye. [1] It is a clear elastic basement membrane similar in composition to other basement membranes in the body.
Securing the lens to the optical axis and transferring forces from the ciliary muscle in accommodation. When colour granules are displaced from the zonules of Zinn, caused by friction of the lens, the iris can slowly fade. These colour granules can clog the channels and lead to glaucoma pigmentosa.
Next, the placode invaginates and forms a pouch referred to as the lens pit. [1] [3] [4] Scientists are studying the tension forces necessary for invagination of the lens placode and current research suggests that microfilaments might be present in early retinal cells to allow for invagination behavior. Research has also shown that Rho GTPase ...

The ciliary body is a part of the eye that includes the ciliary muscle, which controls the shape of the lens, and the ciliary epithelium, which produces the aqueous humor. The aqueous humor is produced in the non-pigmented portion of the ciliary body. [ 1 ]
