FREE! - Label Parts of the Eye Worksheet | Sense of Sight - Free Printable

It looks like you've uploaded an image of a worksheet titled "Parts of the Eye", which asks students to label the parts of the eye in two diagrams: one showing the external view of the eye and the other showing a cross-sectional (internal) view.

Since I can't directly view or process images, I’ll help you solve this based on standard anatomy. Below is a step-by-step guide to labeling both diagrams correctly, along with explanations.

🔍 Diagram 1: External View of the Eye

This diagram shows the visible outer structures of the eye.

Key Parts to Label (with explanations):

1. Eyelid – The fold of skin that covers the eye.
2. Eyebrow – The hair above the eye that helps direct sweat away from the eye.
3. Pupil – The black circular opening in the center of the eye that allows light in.
4. Iris – The colored part of the eye surrounding the pupil; it controls the size of the pupil.
5. Cornea – The clear, dome-shaped front surface of the eye that helps focus light.
6. Sclera – The white, tough outer layer of the eye (commonly called the "white of the eye").
7. Lacrimal gland – Located near the upper outer corner of the eye; produces tears.
8. Conjunctiva – Thin membrane covering the sclera and lining the eyelids.

> ✔ Tip: In many worksheets, the lens may not be visible externally, so only external features are labeled here.

🔍 Diagram 2: Cross-Sectional View of the Eye

This shows internal structures of the eye.

Key Parts to Label (with explanations):

1. Cornea – Transparent front layer.
2. Iris – Colored ring around the pupil.
3. Pupil – Central opening.
4. Lens – Behind the iris; focuses light onto the retina.
5. Ciliary body – Muscles that control the shape of the lens.
6. Vitreous humor – Gel-like fluid filling the back of the eye.
7. Retina – Light-sensitive layer at the back of the eye; converts light into nerve signals.
8. Optic nerve – Carries visual information from the retina to the brain.
9. Choroid – Layer between retina and sclera; contains blood vessels.
10. Sclera – Tough outer coat.
11. Aqueous humor – Fluid in the front chamber of the eye.
12. Ciliary muscle – Part of the ciliary body that adjusts the lens.
13. Macula / Fovea – Small area in the center of the retina responsible for sharp central vision (sometimes included).
14. Blind spot – Area where the optic nerve exits the eye; no photoreceptors.

> ✔ Tip: The optic nerve and retina are often highlighted because they're crucial for vision.

If you can describe what labels are already filled in or which parts are missing, I can give more specific guidance! Otherwise, use this list to fill in the blanks accurately.
