third occipital nerve. third occipital nerve n. The mediodorsal branch of the third cervical nerve, usually joined with the greater occipital nerve but also existing as an independent nerve having cutaneous branches to the scalp and the nape.
Third cranial (oculomotor) nerve disorders that cause palsies and affect the pupil commonly result from aneurysms (especially of the posterior communicating artery) and transtentorial brain herniation (see Brain herniation.) and less commonly from meningitis affecting the brain stem (eg, TB meningitis).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. and less commonly from meningitis affecting the brain stem (eg, TB meningitis). 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.
