THEATER 335 Lecture Notes - Lecture 7: Optic Chiasm, Vitreous Body, Fiber Bundle
Document Summary
The lens is the transparent surface behind the iris and is suspended by the zonule fibers that are attached to the ciliary muscles. The ciliary muscles attach to the sclera to form a ring inside the eye. Relaxation of the ciliary muscles causes the ring to get bigger and the tension on the zonule fibers increases. The lens also divides the interior of the eye into two compartments containing different fluids: the aqueous humor between the cornea and the lens, the vitreous humor between the lens and the retina. Cornea the black dot in the middle of the iris. Glassy, transparent external surface of the eye that covers the pupil and the iris the iris and the.
