Let's solve this eye anatomy labeling puzzle step by step.

Objective:

Label the parts of the human eye using the provided terms.

---

Step 1: Understand the Eye Structure

The diagram shows a cross-section of the human eye. We need to identify each labeled part based on its location and function.

---

Step 2: Identify Each Part

We’ll go from left to right, top to bottom, matching the blank labels with the correct anatomical term.

---

#### Left Side (Anterior Structures – Front of the Eye)

1. Topmost label (outer transparent layer in front):
→ CORNEA
*(Clear, dome-shaped outer layer that covers the iris and pupil)*

2. Just below cornea:
→ IRIS
*(Colored ring around the pupil; controls light entry)*

3. Center of the iris:
→ PUPIL
*(Black circular opening in the center of the iris)*

4. Behind the pupil:
→ LENS
*(Transparent structure that focuses light onto the retina)*

5. Between cornea and lens:
→ AQUEOUS HUMOR
*(Clear fluid filling the anterior chamber of the eye)*

6. Surrounding the lens:
→ CILIARY BODY
*(Structure that produces aqueous humor and holds the lens via suspensory ligaments)*

7. Connecting ciliary body to lens:
→ SUSPENSORY LIGAMENT
*(Fibers that hold the lens in place)*

8. Middle layer behind the lens:
→ CHOROID
*(Vascular layer between sclera and retina; supplies nutrients)*

9. Innermost layer at the back:
→ RETINA
*(Light-sensitive layer containing photoreceptors)*

10. Central area of retina:
→ FOVEA
*(Area of sharpest vision; high concentration of cones)*

---

#### Right Side (Posterior Structures – Back of the Eye)

1. Outer white layer of the eye:
→ SCLERA
*(White, tough outer layer of the eye)*

2. Inside the sclera, behind the choroid:
→ VITREOUS HUMOR
*(Gel-like substance filling the space between lens and retina)*

3. Where optic nerve exits the eye:
→ OPTIC DISK
*(Blind spot; where the optic nerve leaves the eye)*

4. Nerve carrying visual signals from retina to brain:
→ OPTIC NERVE
*(Also known as cranial nerve II)*

5. Blood vessel supplying the retina:
→ CENTRAL ARTERY
*(Branches of the ophthalmic artery that supply blood to the retina)*

---

✔ Final Labeling:

Now let’s assign each label to the correct position on the diagram:

#### Left Side (from top to bottom):
1. CORNEA
2. IRIS
3. PUPIL
4. LENS
5. AQUEOUS HUMOR
6. CILIARY BODY
7. SUSPENSORY LIGAMENT
8. CHOROID
9. RETINA
10. FOVEA

#### Right Side (from top to bottom):
1. SCLERA
2. VITREOUS HUMOR
3. OPTIC DISK
4. OPTIC NERVE
5. CENTRAL ARTERY

📌 Summary:

All the labeled parts have been correctly matched based on standard human eye anatomy. This diagram illustrates key structures involved in vision, including light entry (cornea, pupil), focusing (lens), image detection (retina, fovea), and signal transmission (optic nerve).
