Question
- A. They loosen
- B. They tighten
- C. They break
- D. They remain unchanged
Answer
The correct option is They tighten. This answer is correct because it matches the approved learning objective to explain how ciliary muscles and suspensory ligaments change the shape of the lens during accommodation in the subtopic The eye (biology only).
Explanation
The correct option is They tighten. They tighten is correct because it directly supports the approved learning objective to explain how ciliary muscles and suspensory ligaments change the shape of the lens during accommodation. This belongs to the subtopic The eye (biology only) within The human nervous system, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from The eye (biology only).
Common mistake
Ciliary Muscles and Suspensory Ligaments Function
Students often confuse the roles of ciliary muscles and suspensory ligaments during accommodation, thinking they both contract or relax in the same way.
Remember that when focusing on near objects, ciliary muscles contract, causing the lens to become thicker, while suspensory ligaments loosen. For distant objects, ciliary muscles relax and suspensory ligaments tighten, making the lens thinner.
