In this article we shall look at the anatomy of the oculomotor nerve – its anatomical course, functions and clinical correlations. Se hela listan på wikiskripta.eu The mechanisms of damage can be distinguished by: 1) partial tearing of the parasympathetic fibres contused against the petroclinoid ligament, 2) total tearing of the parasympathetic nerve root, 3) complete tear of one or both oculomotor nerves at the interpeduncular base, 4) nerve root tear, resulting from vessel perforation.

It can presents in different ways causing somatic extraocular muscle dysfunction (superior, inferior, and medial recti; inferior oblique; and levator palpebrae superioris) and autonomic (pupillary sphincter and ciliary) muscles. In addition, with oculomotor nerve damage, patients lose their pupillary constriction to light and strength of the eyelid muscle. The oculomotor nerves (third cranial nerves) originate in the midbrain ( Fig. 4-5 ) and supply the pupil constrictor, eyelid, and adductor and elevator muscles of each eye (medial rectus, inferior oblique, inferior rectus, and superior rectus). The most common cause of palsies that spare the pupil, particularly partial palsies, is Ischemia of the 3rd cranial nerve (usually due to diabetes or hypertension) or of the midbrain Occasionally, a posterior communicating artery aneurysm causes oculomotor palsy and spares the pupil.

The mechanisms of damage can be distinguished by: 1) partial tearing of the parasympathetic fibres contused against the petroclinoid ligament, 2) total tearing of the parasympathetic nerve root, 3) complete tear of one or both oculomotor nerves at the interpeduncular base, 4) nerve root tear, resulting from vessel perforation.

Peripheral neuropathy, a result of damage to the nerves outside of the brain and spinal cord (peripheral nerves), often causes weakness, numbness and pain, usually in your hands and feet. It can also affect other areas of your body. 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. Gross anatomy Nuclei.
