Step 1
This allows the lens to become more globular (thicker and rounder). This is because the lens is naturally elastic and wants to be round, but the suspensory ligaments pull it flat. When the ciliary muscles contract, they relax the suspensory ligaments, allowing the Show more…

If you look away from this book and focus your eyes on a distant object, the eye muscles____ and the lenses _____ focus images on the retinas. a. relax.... flatten b. relax ... become more rounded c. contract.... flatten d. contract... become more rounded
Which reactions occur when a person looks at a distant object? (a) pupils constrict, ciliary zonule (suspensory ligament) relaxes, Ienses become less convex; (b) pupils dilate, ciliary zonule becomes taut, lenses become less convex; (c) pupils dilate, ciliary zonule becomes taut, lenses become more convex; (d) pupils constrict, ciliary zonule relaxes, lenses become more convex.
