Human Extraocular Muscles

Cartoon showing attachment of the human 6 extraocular muscles to the eyeball.

Legend About the Muscles
  • IR - inferior rectus
  • SR - superior rectus
  • LR - lateral rectus
  • MR - medial rectus
  • SO - superior oblique
  • IO - inferior oblique
  • Five of the six muscles (inferior rectus, superior rectus, lateral rectus, medial rectus, and superior oblique) originate at a common tendinous ring of fibrous tissue (the Annulus of Zinn).
    • The Annulus of Zinn surrounds the optic nerve, ophthalmic artery, and ophthalmic vein at their entrance through the apex of the orbit.
  • The sixth muscle (inferior oblique) has a separate origin point on the orbital side of the bony maxilla at the anterior inferomedial strut.

Muscle Structure Each muscle has 2 equal sized layers:

  1. inner global layer - inserts on the eye.
  2. outer orbital layer - inserts on a connective tissue ring.
