The Parts of Our Eye worksheet - Free Printable

Let's solve this step-by-step by identifying and labeling the parts of the eye based on the diagram and the provided word bank.

Word Bank:

- Retina
- Lens
- Pupil
- Cornea
- Optic Nerve
- Iris

Step 1: Understand the Eye Diagram

We are given a cross-sectional view of the human eye. Let’s analyze each labeled blank and match it with the correct part using anatomical knowledge.

Step 2: Identify Each Part

#### 1. Top Left Arrow (Pointing to the clear outer layer at the front):
- This is the Cornea.
- The cornea is the transparent, dome-shaped front surface of the eye that helps focus light.

✔ Label: Cornea

---

#### 2. Middle Left Arrow (Pointing to the black circular opening):
- This is the Pupil.
- The pupil is the dark center of the eye that allows light to enter.

✔ Label: Pupil

---

#### 3. Bottom Left Arrow (Pointing to the colored ring around the pupil):
- This is the Iris.
- The iris is the colored part of the eye that controls the size of the pupil.

✔ Label: Iris

---

#### 4. Central Arrow (Pointing to the lens behind the pupil):
- This is the Lens.
- The lens focuses light onto the retina.

✔ Label: Lens

---

#### 5. Right Side Arrow (Pointing to the back inner lining of the eye):
- This is the Retina.
- The retina contains photoreceptor cells (rods and cones) that convert light into electrical signals.

✔ Label: Retina

---

#### 6. Bottom Right Arrow (Pointing to the nerve exiting the eye):
- This is the Optic Nerve.
- The optic nerve carries visual information from the retina to the brain.

✔ Label: Optic Nerve

Final Answer:

Now, label the boxes accordingly:

1. Top left box (Cornea) → Cornea
2. Middle left box (Pupil) → Pupil
3. Bottom left box (Iris) → Iris
4. Central box (Lens) → Lens
5. Right side box (Retina) → Retina
6. Bottom right box (Optic Nerve) → Optic Nerve

---

✔ Completed Labels:

- Cornea – top left
- Pupil – middle left
- Iris – bottom left
- Lens – center
- Retina – right side
- Optic Nerve – bottom right

---

This completes the labeling of the parts of the eye using the word bank. Each part plays a vital role in vision: light enters through the cornea, passes through the pupil, is controlled by the iris, focused by the lens, detected by the retina, and sent to the brain via the optic nerve.
