VI N. Abducens
—The sixth nerve, the abducens, arises from the medulla, as already described (Fig. 138, VI, and page 347). It passes into the orbit through the orbital fissure, then extends obliquely cranioventrad along the medial surface of the lateral rectus muscle (Fig. 154, k). At about the middle of the length of the muscle it divides into two or three branches which enter at once into the lateral rectus and supply it.
