1. Extraocular muscles: These are the six muscles that control the movement of the eye. They include the superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique muscles. These muscles work together to move the eye in different directions, allowing us to focus on objects at different distances.
2. Levator palpebrae superioris: This muscle is responsible for raising the upper eyelid, allowing us to open and close our eyes.
3. Orbicularis oculi: This muscle encircles the eye and is responsible for closing the eyelids, protecting the eye from foreign objects and regulating the amount of light entering the eye.
4. Ciliary muscles: These muscles control the shape of the lens in the eye, allowing us to focus on objects at different distances. Contraction of the ciliary muscles causes the lens to thicken, enabling us to see objects up close, while relaxation of the muscles allows the lens to flatten for distant vision.
5. Iris muscles: The iris is the colored part of the eye that controls the size of the pupil, regulating the amount of light entering the eye. The sphincter pupillae muscle constricts the pupil in bright light, while the dilator pupillae muscle dilates the pupil in dim light.
Overall, the muscles of the eye work together to control eye movements, regulate the amount of light entering the eye, and enable us to focus on objects at different distances.

Muscles of the Eye and Their Functions
Extraocular Muscles:
- Superior Rectus: Elevates and medially rotates the eye.
- Inferior Rectus: Depresses and medially rotates the eye.
- Lateral Rectus: Abducts (moves laterally) the eye.
- Medial Rectus: Adducts (moves medially) the eye.
- Superior Oblique: Depresses and laterally rotates the eye.
- Inferior Oblique: Elevates and laterally rotates the eye.
Intraocular Muscles:
- Ciliary Muscles: Contracts to change the shape of the lens, focusing light on the retina.
- Pupillary Sphincter: Contracts to constrict the pupil, allowing less light to enter the eye.
- Pupillary Dilator: Contracts to dilate the pupil, allowing more light to enter the eye.
