On emerging from the brain, the nerve is invested with a sheath of pia mater, and enclosed in a prolongation from the arachnoid. There are two cranial nerve nuclei whose neurons contribute axons to the oculomotor nerve: The oculomotor nucleus lies in the midbrain anterior to the periaqueductal grey matter at the level of the superior colliculus anterior to the cerebral aqueduct. The fibers run through the tegmentum, red nucleus and medial aspect of the substantia nigra. oculomotor nucleus This is the nucleus of the oculomotor nerve (third cranial nerve). It is a complex mass of cells located in the midbrain at the level of the superior colliculus and beneath the cerebral aqueduct (of Sylvius) which connects the third and fourth ventricles. It is divided into several subnuclei.
