  1. ^ A technical exception to this rule occurs in the nucleus of the third cranial nerve. The oculomotor nuclear complex contains subnuclei for each of the ocular muscles that it innervates. Axons from one of these subnuclei, the medial nucleus, decussate before exiting the nucleus itself. The medial nucleus of the oculomotor nuclear complex controls the contralateral superior rectus muscle. Cf. Aktekin M, Aldur MM, Bayramoglu A, Atasever A, Ozturk AH, Basar R.
