extraocular muscles

The extraocular muscles are the six muscles that insert onto the eye and hence control eye movements:

• superior rectus: elevation
• superior oblique: intorsion
• medial rectus: adduction
• lateral rectus: abduction
• inferior oblique: extorsion
• inferior rectus: depression

Arterial supply

Muscular branches of ophthalmic artery.

Venous drainage

• superior ophthalmic vein to cavernous sinus
• inferior ophthalmic vein to cavernous sinus and/or pterygoid plexus
• infraorbital vein to pterygoid plexus

Innervation

• oculomotor nerve:
  • superior division: superior rectus muscle
  • inferior division: medial rectus, inferior rectus, and inferior oblique muscles
• trochlear nerve:
  • superior oblique muscle
• abducens nerve:
  • lateral rectus muscle

Associated pathology

• ophthalmoplegia
