Question

What type of striated muscles constitute the muscles of the eyeball? How is this specific type of muscles advantageous?

Answer 1

Six striated ocular muscles attatch the sclera of the eye-ball to the eye-socket. The pairs of extrinsic eye muscles include: (1) inferior and superior rectus muscles, (2) lateral and medial rectus muscles, and (3) inferior and superior oblique muscles. The superior and inferior rectus, move the eye up and down when the eye is rotated away from the nose. When the eye is turned toward the nose, the inferior oblique muscle is responsible for elevating the eye, turning the top of it away from the nose, and moving it outward. medial rectus muscle works to keep the pupil closer to the midline of the body. It helps to move the eye up and down.
