Muscles of the Eye

Muscles Of The Eye

Our eyes are an important part of our body. It helps us see the wonderful things around us. Muscles of the eye are muscles that aid in positioning and moving of the eyeball. You can Check the gallery of images of the eye to know the muscles in the eye better.

An eye has six muscles that control its movement.

These muscles include:

  • Superior rectus muscle
  • Superior oblique muscle
  • Inferior rectus muscle
  • Inferior oblique muscle
  • Lateral rectus muscle
  • Medial rectus muscle

The four rectus eye muscles originate from a common point called the common tendinous ring. Unlike oblique muscles, they pass straight to the front part of the eyeball where they get attached to the sclera.

Oblique muscles move at an angle and get attached to the posterior of the eyeball.

Each of these eye muscles plays a particular role in the upward, downward, sideways movement of the eye. Rotation of the eye is also made possible by some of these muscles.Muscles Of The Eye

Superior rectus muscle

This originates from the common tendinous ring and moves straight to attach itself to the sclera in front of the eyeball.  Superior rectus muscle turns the eye upward.

Superior oblique muscle

It originates from sphenoid bone and gets attached behind the superior rectus in the sclera.  This muscle rotates the eye medially.

Inferior oblique muscle

It originates from the orbital floor and gets attached just behind lateral rectus in the sclera.  This muscle rotates the eye sideways.

Inferior rectus muscle

Like the other rectus muscles, it originates from the common tendinous ring and attaches itself to the lower part of the sclera.  This eye muscle turns the eye downward.

Lateral rectus muscle

It has a common origin with the other rectus muscles. It moves straight to attach itself to both sides of the sclera horizontally.  This muscle turns the eye outward in the direction of the ear.

Medial rectus muscle

It originates from the tendinous ring, and it is attached to the sclera.  This is an eye muscle that turns the eye inwardly in the direction of the nose.

In conclusion, all the six muscles of the eye work together to regulate the position and eye movement.
