Eye Parts

Eyeball Exterior

Diagram of external parts of the eye with descriptions


Eye Part, Front Exterior

6 muscles, move the eye into 9 different positions of gaze. There are 4 straight and 2 oblique muscles.

The two horizontal muscles move the eye left or right. The remaining muscles have a combined effect of vertical movement and partial rotation of the eye. This keeps the picture that we see straight when we tilt our head.

This right eye would move down and left if the pulley muscle acted, or up and left if the lowest (inferior oblique) muscle acted.


Eye PART, Back Exterior

The 4 straight muscles travel from the front white of the eye (sclera) back to the deepest part of the eye socket with the optic nerve.

The two oblique muscles attach to the back of the eye, internally this region is the sharp seeing part of the eye (the macula).
