Cranial Nerve VII?
- Sensory & Motor
- Function: taste on the anterior 2/3 of the tongue and salivary glands, transmission of sensory info from the ear to the brain, control of muscles used in facial expression.
- Assessment: have the patient repeat a sentence. Observe facial expression for any asymmetry, tics, or other facial movements. Next ask the patient to smile, frown, puff out cheeks. Look for symmetry especially in the nasolabial folds. Close his eyes tightly and you try to open them to test strength. For taste, drop a few drops of sweet or salty water on the front part of the tongue.
