Which component of the eye is a stringy membrane holding the lens in place?

Explanation:
The lens is held in place by the suspensory ligaments (zonular fibers), a stringy membrane that runs from the ciliary body to the lens capsule. This network keeps the lens centered and transmits changes in tension to adjust the lens shape during focusing. When the ciliary muscle contracts, the zonular fibers loosen, the lens becomes more curved for near vision; when the ciliary muscle relaxes, the zonules tighten and the lens flattens for distant vision. The retina sits at the back of the eye as the light-detecting layer, while the cochlea and auditory canal are parts of the ear, not involved in anchoring the lens.
