The oculomotor nerve is responsible for the nerve supply to muscles around the eye, including the upper eyelid muscle, which raises the eyelid; the extraocular muscle, which moves the eye inward; and the pupillary muscle, which constricts the pupil.
Nerve, oculomotor: The oculomotor nerve is the third cranial nerve. (The cranial nerves emerge from or enter the cranium, the skull, as opposed to the spinal nerves which emerge from the vertebral column). The oculomotor nerve is responsible for the nerve supply to muscles about the eye: 1  The upper eyelid muscle which raises the eyelid; 2  The extraocular muscle which moves the eye inward; and. 3  The pupillary muscle which constricts the pupil. Oculomotor nerve: The third cranial nerve. The oculomotor nerve is responsible for the nerve supply to muscles around the eye, including the upper eyelid muscle, which raises the eyelid; the extraocular muscle, which moves the eye inward; and the pupillary muscle, which constricts the pupil.  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. abducens nucleus Nucleus of the abducens nerve (sixth cranial nerve) located in the lower part of the pons and whose axons supply the lateral rectus muscle. accessory oculomotor nucleus See Edinger-Westphal nucleus. Comments. comments. Oculomotor Nerve Definition: is the 3rd of 12 paired cranial nerves. It enters the orbit via the superior orbital fissure and controls most of the eye’s movements, including constriction of the pupil and maintaining an open eyelid by innervating the levator palpebrae superioris muscle.

Oculomotor Nerve Nuclei ,Origin,Course,Branches,Testing and palsy Definition of OCULOMOTOR NERVE. : either of the pair of chiefly motor nerves that comprise the third pair of cranial nerves, arise from the midbrain, and supply four muscles of the eye. ADVERTISEMENT. noun. The oculomotor nerve originates from the third nerve nucleus at the level of the superior colliculus, in the midbrain. The third nerve nucleus is located lateral to the cerebral aqueduct, on the pre-aqueductal grey matter. There are two nuclei for the oculomotor nerve: 1  The oculomotor nucleus originates at the level of the superior colliculus. 2  The muscles it controls are the striated muscle in levator palpebrae superioris and all extraocular muscles except for the superior oblique muscle and the lateral rectus muscle. The oculomotor nerve is the third cranial nerve. It enters the orbit via the superior orbital fissure and innervates muscles that enable most movements of the eye and that raise the eyelid. There are two nuclei for the oculomotor nerve: 1  The oculomotor nucleus originates at the level of the superior colliculus. 2  The muscles it controls are the striated muscle in levator palpebrae superioris and all extraocular muscles except for the superior oblique muscle and the lateral rectus muscle. pertaining to or affecting eye movements. oculomotor nerve. the third cranial nerve; it contains motor and parasympathetic 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. See also Table 14. 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 From Wikipedia, the free encyclopedia. Oculomotor nerve palsy or third nerve palsy is an eye condition resulting from damage to the third cranial nerve or a branch thereof. As the name suggests, the oculomotor nerve supplies the majority of the muscles controlling eye movements.
