Muscle of eye
Muscle of eye
✅ 1. Based on Location
🔹 Extraocular Muscles (outside the eyeball – control movement)
- Superior Rectus
- Inferior Rectus
- Medial Rectus
- Lateral Rectus
- Superior Oblique
- Inferior Oblique
🔹 Intraocular Muscles (inside the eyeball – control internal eye functions)
- Ciliary Muscle
- Sphincter Pupillae
- Dilator Pupillae
Based on Direction of Action
🔹 Vertical Movers
Superior Rectus – Moves eye up
Inferior Rectus – Moves eye down
Superior Oblique – Moves eye down and out
Inferior Oblique – Moves eye up and out
🔹 Horizontal Movers
Medial Rectus – Moves eye inward (towards nose)
Lateral Rectus – Moves eye outward (away from nose)
🔹 Intraocular Muscles (inside the eyeball – control internal eye functions)
🔸 Controllers of the Pupil and Lens
(Responsible for focusing and light adjustment)
Ciliary muscle – for accommodation
Sphincter pupillae – constricts pupil
Dilator pupillae – dilates pupil
✅ 3. Based on Nerve Supply
Muscle Nerve Supply
Superior oblique - Trochlear nerve (CN IV)
Lateral rectus - Abducent nerve (CN VI)
All others - Oculomotor nerve (CN III)
