How many extraocular muscles are responsible for moving each eye?

The correct answer indicates that there are six extraocular muscles responsible for the movement of each eye. These muscles are critical for coordinating eye movements, allowing for a range of motions, including up, down, left, right, and rotation. The six muscles consist of the superior rectus, inferior rectus, medial rectus, lateral rectus, superior oblique, and inferior oblique. Each muscle has a specific role in controlling eye position and ensuring that both eyes work together during gaze shifts. This coordination is essential for maintaining proper visual alignment and depth perception.

Understanding the function and arrangement of these muscles is fundamental in fields such as ophthalmology and neurology, as variations or dysfunctions can lead to vision issues, such as strabismus.
