The movements of different body parts are controlled by striated muscles acting around joints. The movements of the eye are no exception, but they have special advantages not shared by skeletal muscles and joints, and so are considerably different.
Extraocular muscles
Each eye has six muscles that control its movements: the lateral rectus, the medial rectus, the inferior rectus, the superior rectus, the inferior oblique, and the superior oblique. When the muscles exert different tensions, a torque is exerted on the globe that causes it to turn. This is an almost pure rotation, with only about one millimeter of translation. Thus, the eye can be considered as undergoing rotations about a single point in the center of the eye.
Please see the webpage for more details on Extraocular muscles.

The extraocular muscles are all skeletal muscle. Although, interestingly, they are some of the more unusual skeletal muscle fibers in the body and some of their connections with nerves are also unusual compared to other skeletal muscles.

their are sex skeletal muscles of the eye which keep it in the corect position and keep its movement they are called : 1) lateral rectus 2) medial rectus 3)inferior rectus 4) superior rectus 5) superior oblique 6)inferior oblique
the smooth muscle of the eye they are :

extraocular muscles control eye movements. these are skeletal muscles innervated by cranial nerves III, IV, and VI. there are 7 EOMs: superior oblique (CN IV), inferior oblique, superior rectus, inferior rectus, medial rectus, lateral rectus (CN VI), and the levator palpebrae superioris (all the rest are innervated by CN III)
