  2. Physiology
    1. Innervates extraocular lateral rectus muscle
    2. Moves eye laterally
    3. Long thin nerve that is susceptible to compression (Cranial Nerve 4 and 6 are similar in this way)
      1. Paralysis (unilateral or bilateral) may occur even with generalized Increased Intracranial Pressure
      2. Contrast with the Cranial Nerve 3 which is a thick cable-like nerve requiring significant compression for paralysis
  3. Course
    1. Nucleus lies beneath facial colliculus
    2. Runs below clinoid process
    3. Passes through Cavernous Sinus
    4. Enters orbit through superior orbital fissure
  4. Pathophysiology
    1. Bilateral paralysis seen in Botulism

Abducens nerve structure (C0000741)

Definition (NCI) A cranial nerve that supplies motor impulses to the lateral rectus muscle of the eye.
Definition (MSH) The 6th cranial nerve. The abducens nerve originates in the abducens nucleus of the pons and sends motor fibers to the lateral rectus muscles of the eye. Damage to the nerve or its nucleus disrupts horizontal eye movement control.
