It emerges from the anterior aspect of the midbrain, passing inferiorly to the posterior cerebral artery and superiorly to the superior cerebellar artery. This nerve is responsible for eyeball and eyelid movement. It follows the olfactory and optic nerves in terms of order.

Nervus oculomotorius nucleus

2013-09-04 The oculomotor nerve (third cranial nerve, CN III, latin: nervus oculomotorius) is a mixed cranial nerve containing motor and parasympathetic fibers.The general somatic efferent fibers of the oculomotor nerve supply the levator palpebrae superioris and four of the six extraocular muscles: the medial, superior, and inferior recti, and the inferior oblique muscles. The oculomotor nerve sends motor fibers to the levator muscles of the eyelid and to the superior rectus, inferior rectus, and inferior oblique muscles of the eye. It also sends parasympathetic efferents (via the ciliary ganglion) to the muscles controlling pupillary constriction and accommodation.

Nervus oculomotorius nucleus

accessory nuclei of oculomotor nerve. The oculomotor nucleus is a somatic motor nucleus which provides the oculomotor nerve with general somatic efferent fibers. The accessory nuclei of the oculomotor nerve are parasympathetic nuclei, among which the clinically most important one is the Edinger-Westphal nucleus. The oculomotor nerve originates from the oculomotor nucleus - located within the midbrain of the brainstem, ventral to the cerebral aqueduct. It emerges from the anterior aspect of the midbrain, passing inferiorly to the posterior cerebral artery and superiorly to the superior cerebellar artery. The oculomotor nerve is the third of twelve paired cranial nerves.It controls most of the eye's movements, constriction of the pupil, and maintains an open eyelid.

1A). Thus, it can be considered as being in the center of the tegmentum. The fibers of the oculomotor nerve pass ventrally through the ipsilateral red nucleus and then exit the ventral midbrain along the medial cerebral peduncle. The nucleus of the oculomotor nerve does not consist of a continuous column of cells, but is broken up into a number of smaller nuclei, which are arranged in two groups, anterior and posterior. Those of the posterior group are six in number, five of which are symmetrical on the two sides of the middle line, while the sixth is centrally placed and is common to the nerves of both sides.

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.
