- In addition to the above, if mass effect is present with resulting displacement of brain tissue, additional signs may include pupillary dilatation, abducens palsies, and the Cushing's triad.
- The abducens nucleus along with the internal genu of the facial nerve make up the facial colliculus, a hump at the caudal end of the medial eminence on the dorsal aspect of the pons.
- A pituitary tumour may also extend into the cavernous sinus, compressing the oculuomotor nerve ( III ), trochlear nerve ( IV ) and abducens nerve ( VI ), leading to double-vision and strabismus.
- Focal neurological deficits may also occur, such as abducens nerve palsy and vertical gaze palsy ( Parinaud syndrome due to compression of the quadrigeminal plate, where the neural centers coordinating the conjugated vertical eye movement are located ).
- Unlike the nerves listed above, the abducens nerve ( CN VI ) does not run within the lateral wall of the cavernous sinus; rather, it runs through the middle of the sinus alongside the internal carotid artery.
- Abducens nerve palsy is also known to occur with halo orthosis placement . The resultant palsy is identified through loss of lateral gaze after application of the orthosis and is the most common cranial nerve injury associated with this device.
- As far as the non-wiki stuff you brought up, I was banned from the Outpost because I protested the treatment of Abducens ( who by the way, was ultimately reinstated, but refused to return ).
- The control of conjugate gaze is mediated in the brainstem by the medial longitudinal fasciculus ( MLF ), a nerve tract that connects the three extraocular motor nuclei ( abducens, trochlear and oculomotor ) into a single functional unit.
- The central anatomy of the sixth nerve predicts ( correctly ) that infarcts affecting the dorsal pons at the level of the abducens nucleus can also affect the facial nerve, producing an ipsilateral facial palsy together with a lateral rectus palsy.
- Internuclear ophthalmoplegia occurs when MS affects a part of the brain stem called the medial longitudinal fasciculus, which is responsible for communication between the two eyes by connecting the abducens nucleus of one side to the oculomotor nucleus of the opposite side.
- But children are certainly going to be put off by the rampant medical jargon, as in " the abducens nerve is the sixth cranial nerve and extends from the dorsal part of the pons to the lateral rectus muscle of the eye ."
- The abducens nucleus contains two types of cells : motor neurons that control the lateral rectus muscle on the same side, and interneurons that cross the midline and connect to the contralateral oculomotor nucleus ( which controls the medial rectus muscle of the opposite eye ).
- Fissure changes, and the other associated characteristics of Duane's such as up or down shoots and globe retraction, are also vital when deciding whether any abduction limitation is the result of Duane's and not a consequence of VI or abducens cranial nerve palsy.
- "' Sixth nerve palsy "', or "'abducens nerve palsy "', is a disorder associated with dysfunction of cranial nerve VI ( the abducens nerve ), which is responsible for causing contraction of the lateral rectus muscle to eye.
- "' Sixth nerve palsy "', or "'abducens nerve palsy "', is a disorder associated with dysfunction of cranial nerve VI ( the abducens nerve ), which is responsible for causing contraction of the lateral rectus muscle to eye.
- Together, trochlear and abducens contract and relax to simultaneously direct the pupil towards an angle and depress the globe on the opposite side of the eye ( e . g . looking down directs the pupil down and depresses ( towards the brain ) the top of the globe ).
- The sixth nerve, the abducens nerve, which innervates the lateral rectus muscle of the eye ( moves the eye laterally ), is also commonly affected but fourth nerve, the trochlear nerve, ( innervates the superior oblique muscle, which moves the eye downward ) involvement is unusual.
- A generalized increase in intracranial pressure hydrocephalus, pseudotumor cerebri, hemorrhage, edema will affect the fourth nerve, but the abducens nerve ( VI ) is usually affected first ( producing "'horizontal diplopia "', not "'vertical diplopia "').
- Cavernous sinus syndrome may result from mass effect of these tumors and cause ophthalmoplegia ( from compression of the oculomotor nerve, trochlear nerve, and abducens nerve ), ophthalmic sensory loss ( from compression of the ophthalmic nerve ), and maxillary sensory loss ( from compression of the maxillary nerve ).
- "On Old Olympus'Towering Top A French And German Viewed Some Hops " does not roll off the tongue any quicker than the 12 cranial nerves _ Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Auditory, Glossopharyngeal, Vagus, Spinal Accessory and Hypoglossal.
