(eks-truh-AHK-yu-lur): Six muscles that move the eyeball.
Six muscles control eye movement. Five of these originate from the back of the orbit and wrap around the eye to attach within millimeters of the cornea. Four of these move the eye roughly up, down, left and right. Two muscles (one originating from the lower rim of the orbit) control the twisting motion of the eye (when the head is tilted).
six muscles (medial rectus, lateral rectus, superior rectus, inferior rectus, superior oblique, and inferior oblique) which serve to move an eye by rotating it about its vertical, horizontal, and antero-posterior axes
Six muscles which control eye movement: superior oblique, superior rectus, lateral rectus, inferior oblique, inferior rectus, and medial rectus.
6 external eye muscles that rotate the eyeballs in all directions (so that you can look at a member of the opposite sex without turning your head). Some say that they change the shape of the eyeballs in order to to accommodate, but this old theory of accommodation has been conclusively dismissed by many scientific experiments.
The six muscles that control the movement of the globe of the eye.
external eye muscles which move the eyeball
The six muscles that attach to each eye and rotate the eye into any of the 'positions of gaze'. Any over or underactivity of a muscle will result in double vision ( diplopia).
The six muscles which cause movement of the eye internal and external recti and superior and inferior recti and superior and inferior oblique.
The tiny muscles that surround the eye and control its movements. There are six: the lateral rectus, medial rectus, superior oblique, inferior oblique, superior rectus and inferior rectus. The primary function of the four rectus muscles is to control the eye's movements from left to right and up and down. The two oblique muscles rotate the eyes inward and outward. All six muscles work in unison; when they do not function properly, the condition is called strabismus. Ophthalmologists can present several options for correcting strabismus.

Muscles outside of the eyeball that move the eye
The extraocular muscles are the six muscles that control the movements of the eye. The actions of the extraocular muscles depend on the position of the eye at the time of muscle contraction.
