Quiz #5 study guide- cranial nerves/brainstem/motor systems and control. Effect of lesion: unilateral- no symptoms: optic (ii, bilateral-anosmia. Effect of lesion: unilateral-ipsilateral blindness: occulomotor (iii, bilateral- bilateral blindness. Function: extraocular eye movements up down medially and laterally. Effect of lesion: external strabismus (eye deviates outward) diplopia (double vision) ptosis (dropping of eyelid) nystagmus. Function: extraocular eye movements-down and lateral: motor, nuclei: midbrain. Effect of lesion: unable to move eyeball down and lateral. Function: sensory: sensation of face, head, cornea, and inner oral cavity: motor: jaw muscles for chewing, both (motor and sensory, nuclei: mid pons. Effect of lesion: sensory: ipsilateral loss of sensation to head and face, trigeminal neuraglia: motor: difficulty chewing, jaw deviates to affected side, abducens (vi, motor, nuclei: low pons. Effect of lesion: eyeball is turned inward, diplopia, nystagmus. Function: sensory: taste: motor: muscle of facial expression, close eyelids stapedius muscle in inner eat, both (motor and sensory, nuclei: pons.
