What is the primary role of extra ocular muscles?

The primary role of extraocular muscles is to enable the rotation of the eye. These muscles are responsible for the movement of the eyeball in various directions, which is crucial for proper vision. By contracting and relaxing in specific combinations, these muscles allow the eye to move up and down, side to side, and diagonally. This movement is essential for tracking moving objects, changing focus between different distances, and coordinating with both eyes to provide depth perception and a complete visual field. The precise control offered by the extraocular muscles ensures that we can effectively navigate our environment and engage with visual stimuli.
