oculomotor nerves การใช้

• :Oculomotor nerve originates in the midbrain and innervates several eye muscles.
• The inferior oblique is innervated by the inferior branch of the oculomotor nerve.
• The uncus can squeeze the oculomotor nerve ( a . k . a.
• This is because Horner's syndrome and oculomotor nerve lesions both cause ptosis.
• These cases may be due to brain mass lesions which cause oculomotor nerve palsy.
• Diabetic neuropathy of the oculomotor nerve in a majority of cases does not affect the pupil.
• A brain catastrophe, or a rapidly increasing brain mass, can cause compression of the oculomotor nerve.
• Convergence is classically spared as cranial nerve III ( oculomotor nerve ) and its nucleus is spared bilaterally.
• The nuclei of the oculomotor nerve ( III ) and trochlear nerve ( IV ) are located in the midbrain.
• Since the oculomotor nerve controls most of the eye muscles, it may be easier to detect damage to it.
• When cranial nerves are affected, neuropathies of the oculomotor nerve ( cranial nerve # 3 ) are most common.
• Specific nerves include several cranial nerves, specifically the oculomotor nerve, facial nerve, glossopharyngeal nerve, and vagus nerve.
• This can cause palsy of the facial nerve or oculomotor nerve or hearing loss due to damage of cranial nerve VIII.
• The condition can also result from aplasia or hypoplasia of one or more of the muscles supplied by the oculomotor nerve.
• The oculomotor nerve comes out between the peduncles, and the trochlear nerve is visible wrapping around the outside of the peduncles.
• A complete oculomotor nerve palsy will result in a characteristic " down and out " position in the affected eye.
• This is called herniation and will often cause an enlarged pupil on the affected side, due to pressure on the oculomotor nerve.
• The oculomotor neurons functions to send its axons in the oculomotor nerve, to control the medial rectus, and converge the two eyes.
• It is important to distinguish the ptosis caused by Horner's syndrome from the ptosis caused by a lesion to the oculomotor nerve.
• More rarely, the oculomotor nerve and trochlear nerve ( weakness of the muscles of facial expression on one or both sides of the face.
