Trigeminal nerve function
DEFINITION 9 sensory: carries sensation from face (pain, temp, proprio, touch)motor: supplies muscles of mastication (temporalis and masseter) TERM 10
trigeminal neuralgia
DEFINITION 10 unknown causeroot compression, vascular compressionsevere attacks of unilateral neurogenic pain along the sensory branches of the trigeminal nerve precipitated by movements of jaw, light breeze or extreme tempsusually affects older women
lesion of the oculomotor nerve
ptosisdivergent squint where the eye looks out and down due to unoppoesed action of lateral rectus and superior oblique TERM 17
Function of the trochlear nerve
DEFINITION 17 supplies superior oblique muscle which turns eye in and down TERM 18
lesion of the trochlear nerve
DEFINITION 18 affected eye rotate up and indiplopia only when pt looks downwardattempts to compensate lead to pt tilting head to contralateral side TERM 19
