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.

This muscle is innervated by the superior branch of the oculomotor nerve (CN III). Note that these fibers of oculomotorius originate from the nucleus of oculomotor nerve which is a somatic motor nucleus, thus providing voluntary control over this muscle.

It provides motor and parasympathetic innervation to some of the structures within the bony orbit. In this article we shall look at the anatomy of the oculomotor nerve – its anatomical course, functions and clinical correlations. Der Nervus oculomotorius ist der dritte Hirnnerv und führt somatomotorische und allgemein-viszeromotorische Fasern. Er ist zusammen mit dem Nervus trochlearis und dem Nervus abducens für die Bewegung des Augapfels zuständig. 2 Verlauf. Der Nervus oculomotorius entspringt in der Fossa interpeduncularis zwischen den beiden Crura cerebri.

Oculomotorius; Third Nerve) The oculomotor nerve (Figs. 775, 776, 777) supplies somatic motor fibers to all the ocular muscles, except the Obliquus superior and Rectus lateralis; it also supplies through its connections with the ciliary ganglion, sympathetic motor fibers to the Sphincter pupillæ and the Ciliaris muscles.

functions are exercised through the following anatomical paths: By means of the direct cerebellar tract (Fig. IX, 6 blue) from the n. vestibularis, the cerebellum is connected with the semi- circular canals of N. oculomotorius. 12

It follows the olfactory and optic nerves in terms of order Försämrad/upphörd impulsfortledning i hela eller delar av nervus oculomotorius (n. III) med inskränkt/upphävd adduktion, depression och elevering av det drabbade ögat som följd. Är impulsfortledningen helt upphävd talar man om en oculomotoriusparalys. Om man har kvar en viss funktion talar man om en oculomotoriuspares. It is responsible for the autonomic functions of the oculomotor nerve, including pupillary constriction and lens accommodation.

The oculomotor nucleus is split up into multiple subnuclei. De nervus oculomotorius, in het Nederlands ook wel oogbewegingszenuw, is de derde van de twaalf hersenzenuwen.

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.

Oculomotor nerve (N oculomotorius): A cranial nerve emerging from the the sternocleidomastoid muscle in the neck and functions as a supplementary nerve

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.

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.
