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.

Der Nervus oculomotorius ist der dritte Hirnnerv (III). Er enthält somatoefferente und viszeroefferente Fasern und steuert die meisten quergestreiften Muskeln des Auges an (Ausnahmen: M. obliquus superior und M. rectus lateralis). Neben dem N. trochlearis und dem N. abducens ist er daher maßgeblich für die Bewegungen des Auges verantwortlich.

It is responsible for the autonomic functions of the oculomotor nerve, including pupillary constriction and lens accommodation. Additional images [ edit ] This gallery of anatomic features needs cleanup to abide by the medical manual of style . Function: Innervates the levator palpebrae superioris, superior rectus, medial rectus, inferior rectus, and inferior oblique, which collectively perform most eye movements. Also innervates the sphincter pupillae and the muscles of the ciliary body.

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.

Neuro-anatomical evidence supports the potential for threat-related factors, such as fear, anxiety and vigilance, to influence brainstem motor nuclei controlling eye movements, as well as the vestibular nuclei. However, little is known about how threat influences human ocular responses, such as eye …

VI). Denna nerv innerverar endast m. rectus lateralis vilket gör att paresen leder till en inskränkt eller upphävd abduktionsförmåga av det drabbade ögat som följd. Är impulsfortledningen i nerven helt upphävd talar man om en abducensparalys medan om man har kvar viss funktion […] 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 eye.

Oculomotorius) on sekoittunut, sillä on moottorisia ja autonomisia hermokuituja, jotka ovat keskushermostossa sijaitsevien vastaavien ytimien solujen prosesseja. Oculomotor hermolla on myös herkkiä proprioceptiivisiä kuituja näistä silmämunien lihaksista, Oculomotor Synkinesis (also known as aberrant regeneration of the third cranial nerve or oculomotor nerve misdirection) refers to the abnormal response to firing of the oculomotor nerve causing paradoxical co-contraction (i.e., synkinesis) of muscles.

L.M. Optican, in Encyclopedia of Neuroscience, 2009 The oculomotor system is made up of many brain areas that cooperate to stabilize images of interest on the high-acuity part of the retina. All these systems must funnel through the same final common pathway, the brain stem circuit that compensates for the dynamics of the orbital tissues and muscles (the plant).

It is responsible for the autonomic functions of the oculomotor nerve, including pupillary constriction and lens accommodation. The oculomotor nerve is the third cranial nerve (CN III). 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. 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.
