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.

however, its edges are close to the brainstem Moreover, its role in  Function The oculomotor nerve include axons of type GSE, general somatic efferent, which innervate skeletal muscle of the levator palpebrae superioris, superior rectus, medial rectus, inferior rectus, and inferior oblique muscles. (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. The oculomotor nerve is the third cranial nerve (CNIII), and one instance in which the name is a clear indication of the function of the nerve (Oculo = pertaining to the eye, motor = producing movement).

Somatic (voluntary) functions of the oculomotor nerve include elevation of the upper eyelid via innervation of the levator palpebrae superioris muscle. Other essential functions include coordination of eye muscles for visual tracking and gaze fixation. These functions of eye movement occur through innervation of four eye muscles: Nervus oculomotorius er den tredje hjernenerve.

The oculomotor nerve is the third of the cranial nerves and arises from the midbrain. It is responsible for the movements of four of the six extraocular muscles, the other two being innervated by the trochlear and abducens nerves. The oculomotor nucleus is a small somatic motor nucleus in the midbrain and one of the two nuclei for the oculomotor nerve. Dysfunction of the third cranial nerve (oculomotor nerve) can result from lesions anywhere along its path between the oculomotor nucleus in the midbrain and the extraocular muscles within the orbit. Loss of function of any of the eye muscles results in ophthalmoparesis. Since the oculomotor nerve controls most of the eye muscles, it may be easier to detect damage to it. Damage to this nerve, termed oculomotor nerve palsy , is known by its down and out symptoms, because of the position of the affected eye (lateral, downward deviation of gaze).

Oculomotor Dysfunction occurs when there is the absence or defect of controlled, voluntary, and purposeful eye movement. As you might imagine, accurate and well established oculomotor skills are critical when reading, writing, copying information, working on art projects, finding an object in a background, playing sports and many other activities we perform in our highly visual world.

In this article we shall look at the anatomy of the oculomotor nerve – its anatomical course, functions and clinical correlations. The oculomotor nucleus is found at the level of the superior colliculus.

Ögonmuskelnerven, tredje kranialnerven. Kommer ut ur hjärnarmsgropen på framsidan/undersidan av mitthjärnan och tar sig ut ur skallhålan till ögonhålan. Nerven försörjer motoriskt den övre raka, den inre raka, den nedre raka och den nedre sneda ögonmuskeln, vilka alla fäster på ögonklotet samt ögonlockslyftarmuskeln.
