The extraocular muscles are a group of six muscles that control the movement of the eyeball. These muscles allow the eyes to move in various directions, enabling us to track objects, focus on different points, and maintain proper alignment. The six muscles include the superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique. Each muscle has a specific function, such as elevating, depressing, or rotating the eye. They work together to ensure smooth and coordinated eye movements. Proper functioning of the extraocular muscles is essential for good vision and depth perception.
