The correct Answer is:
To answer the question "At rest, the eyes have," we need to analyze the options provided and understand the role of the ciliary body and the lens in the eye. ### Step-by-Step Solution: 1. **Understanding the Ciliary Body**: - The ciliary body is a part of the eye that contains ciliary muscles, which are responsible for adjusting the shape of the lens for focusing. 2. **Function of Ciliary Muscles**: - When the ciliary muscles are relaxed, the lens of the eye is in a natural, unaccommodated state, which is typically biconvex. This is the state when the eyes are at rest and not focusing on nearby objects. 3. **Analyzing the Options**: - **Option A**: Relaxed ciliary body - This is true when the eyes are at rest. - **Option B**: Contracted ciliary body - This occurs when focusing on nearby objects, not at rest. - **Option C**: Suspensory ligament is loose or relaxed - The suspensory ligaments are taut when the ciliary body is relaxed, so this is not correct. - **Option D**: Eye lens is elastic and biconvex - While the lens is elastic and biconvex, this does not directly answer the question about the state of the ciliary body. 4. **Conclusion**: - The correct answer is **Option A: Relaxed ciliary body**. This state occurs when the eyes are at rest, allowing for a single focus without the need for accommodation.
