Test: Human Anatomy and Physiology

A 65-year old nursing home resident is referred to you from her primary care physician, who is concerned that she may have a neurological deficit. As you proceed to test her cranial nerves, you note her blink reflex is absent (she doesn’t blink when you touch her cornea with a cotton swab). In order to figure out what is wrong, you ask her to make different facial expressions including shutting her eyes tightly, which she successfully does.

Lack of eye movement

Inability to turn her head

Impaired sense of smell

Absent gag reflex

Sensory deficits in the face
