Summary Introduction
To review:
The extrinsic eye muscles responsible for the movement of eyes.
Introduction:
Eyes contain six muscles that are responsible for managing the movement of the eyeballs. The muscle that control the movement of the eye is known as extrinsic eye muscles. These are referred as extrinsic because the origin points are present on the outer surface of the eyeballs and insertion points are present on the outside of the sclera.
