Polioencephalomacia damages the visual cortex, impairing the menace reflex, but leaves the optic nerve, oculomotor nucleus, and oculomotor nerve intact, leaving the pupillary light reflex unaffected.
32.
He is known for his anatomical and physiological investigations of the autonomic nervous system, discovering that sympathetic nerve stimulation brings about pupillary dilatation and that oculomotor nerve stimulus produces constriction.
33.
Lack of the pupillary reflex or an abnormal pupillary reflex can be caused by optic nerve damage, oculomotor nerve damage, brain stem death and depressant drugs, such as barbiturates.
34.
Compressive oculomotor nerve damage could result in compression of the parasympathetic fibers before any disruption of the motor fibers occurs, since the parasympathetic fibers run on the outside of the nerve.
35.
The midbrain tectum, responsible for visual processing in reptiles, was very small in " Tarbosaurus ", as were the optic nerve and the oculomotor nerve, which controls eye movement.
36.
The nucleus of the oculomotor nerve does not consist of a continuous column of cells, but is broken up into a number of smaller nuclei, which are arranged in two groups, anterior and posterior.
37.
His name is also shared with neurologist Ludwig Edinger ( 1855 1918 ) regarding the Edinger Westphal nucleus, which is an accessory nucleus of the oculomotor nerve ( cranial nerve number III; CN III ).
38.
A second set of fibres from the medial and lateral nuclei end partly in the tegmentum, while the remainder ascend in the medial longitudinal fasciculus to arborize around the cells of the nuclei of the oculomotor nerve.
39.
The cranial nerves containing GVE fibers include the oculomotor nerve ( CN III ), the facial nerve ( CN VII ), the glossopharyngeal nerve ( CN IX ) and the vagus nerve ( CN X ).
40.
Damage to the oculomotor nerve ( III ) can cause double vision ( diplopia ) and inability to coordinate the movements of both eyes ( strabismus ), also eyelid drooping ( ptosis ) and pupil dilation ( mydriasis ).
