The oculomotor nerve is the third cranial nerve. It enters the orbit via the superior orbital fissure and innervates extrinsic eye muscles that enable most movements of the eye and that raise the eyelid. The nerve also contains fibers that innervate the intrinsic eye muscles that enable pupillary constriction and accommodation. The oculomotor nerve is derived from the basal plate of the embryonic midbrain. Cranial nerves IV and VI also participate in control of eye movement.

The oculomotor nucleus is a small somatic motor nucleus in the midbrain and one of the two nuclei for the oculomotor nerve.

trigeminus; nn. ophthalmicus og maxillaris også findes. The oculomotorius nerve (n. Oculomotorius) is mixed, has motor and autonomic nervous fibers, which are the processes of the cells of the corresponding nuclei located in the midbrain. In the oculomotor nerve, there are also sensitive proprioceptive fibers from those muscles of the eyeball that innervate this nerve. N. oculomotorius (N.III) The oculomotor nerve is a motor cranial nerve endowed with both somato- and visceromotor components, for which one complex is responsible in each case.

Der paarige Nervus oculomotorius , auch dritter Hirnnerv, N. III genannt, innerviert jederseits vier der sechs äußeren Augenmuskeln und Nervus ulnaris (latin: "armbågsbenets nerv") är, i människans kropp, en nerv som passerar längs med armens mediala sida (ulnar- eller insidan) och försörjer underarmens och handens muskler och hud. Die Untersuchung der Hirnnerven ist essentieller Bestandteil der neurologischen Untersuchung. Auffälligkeiten in der Prüfung lassen häufig schon eine gute Eingrenzung der Lokalisationshöhe zu.

Oculomotor hermolla on myös herkkiä proprioceptiivisiä kuituja näistä silmämunien lihaksista, jotka innervoivat tätä hermoa.

Due to its function in eye movement, the oculomotor nerve is a beneficial indicator of brain injury (15). The most common causes of oculomotor nerve palsy or dysfunction are microvascular diseases, like hypertension , diabetes, tumor, trauma, or aneurysm (16) .

(innervates all the extrinsic muscles except superior oblique and lateral rectus.) The oculomotor nerve is the third of 12 pairs of cranial nerves in the brain. This nerve is responsible for eyeball and eyelid movement. It follows the olfactory and optic nerves in terms of order.
