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. It contains the somatic efferent fibers that control the medial rectus, inferior rectus, superior rectus, inferior oblique, and the striated muscle in the levator palpebrae superioris. The oculomotor nucleus is split up into multiple subnuclei. 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. Gross Anatomy The nucleus is located in the central midbrain at the level of the superior colliculus ventral and medial Kranialnerver är nerver som ansluter direkt till hjärnan eller hjärnstammen. Människan har 12 par kranialnerver som har olika funktion. Kranialnerverna förmedlar dels sensoriska signaler till hjärnan, dels motoriska signaler från hjärnan. De är ansvariga för framför allt huvud och nacke. Nervus oculomotorius er den tredje hjernenerve.
oculomotor [ok″u-lo-mo´tor] pertaining to or affecting eye movements. oculomotor nerve the third cranial nerve; it is mixed, that is, it contains both sensory and motor fibers. Various branches of the oculomotor nerve provide for muscle sense and movement in most of the muscles of the eye, for constriction of the pupil, and for accommodation of the
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). Consist on complete ophthalmic exam including visual acuity, ductions and versions, levator function, pupils reaction to light and to accommodation.

It functions to rotate the eye medially, upwards, and downwards while also being responsible for elevating the upper eyelid. The nerve tract can be described with five segments: the nucleus, fascicles, subarachnoid cistern, cavernous sinus, and intra-orbital segments. Injury to the oculomotor nerve can happen anywhere along this tract. The defeat of the oculomotor (III) nerve (n. Oculomotorius) Alexey Portnov, medical expert Last reviewed: 11.04.2020.
