The human eye is controlled by six small muscles known as the eye muscles. These muscles are responsible for moving the eye in different directions, allowing us to look up, down, left, and right. They work together to ensure that both eyes move in coordination, which is essential for proper vision and depth perception. The six eye muscles include the superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique. Each muscle has a specific function and is attached to the outer layer of the eyeball. Proper functioning of these muscles is crucial for maintaining clear and focused vision.
