Zonules attach to which structure?

Zonules attach to which structure?

• A. Iris
• B. Retina
• C. Ciliary body
• D. Choroid

Answer: (C)

Zonules are the suspensory ligaments that anchor the lens to the ciliary body. They originate from the ciliary processes of the ciliary body and insert into the lens capsule near its equator, holding the lens in place and transmitting tension to change its shape during accommodation. They do not attach to the iris, retina, or choroid, which are separate structures positioned differently in the eye. The iris controls pupil size, the retina is the light-sensitive lining at the back, and the choroid lies between the retina and sclera.
