Question

place a single word into each sentence to make it correct, then place each sentence into a logical paragraph order.

1. in the emmetropic eye, the (click to select) muscle is relaxed and dilated.
2. this puts tension on the suspensory ligament and flattens the (click to select).
3. oppositely, in accommodation, the ciliary muscle contracts and (click to select) the diameter of the ciliary body.
4. this action reduces tension on the (click to select) ligament.
5. this results in the lens forming a (click to select) shape.

(click to select)
concave
enlarges
pupil
narrows
ciliary
convex
lens
suspensory

Explanation:

1. In an emmetropic (normal) eye, the ciliary muscle is relaxed.
2. Relaxed ciliary muscle puts tension on the suspensory ligament, flattening the lens.
3. During accommodation (focusing on near objects), the ciliary muscle contracts and narrows the diameter of the ciliary body.
4. This contraction reduces tension on the suspensory ligament.
5. Reduced tension on the suspensory ligament allows the lens to form a convex shape (for near - vision focusing).

The logical order is based on the normal state (emmetropic) first (sentence 1), then the effect on the lens (sentence 2). Then we move to the opposite process (accommodation) starting with the ciliary muscle contraction (sentence 3), its effect on the suspensory ligament (sentence 4), and finally the lens shape (sentence 5).

Answer:

1. ciliary
2. lens
3. narrows
4. suspensory
5. convex

Logical order: 1, 2, 3, 4, 5
