What is CN X (Vagus)?
A PCA stroke is most associated with this major neurological deficit
What is visual disturbance/vision loss?
A patient has a temporal skull fracture followed by a brief loss of consciousness and then rapid deterioration. Which artery is damaged?
What is the middle meningeal artery?
This pathway carries voluntary motor commands from the brain to skeletal muscle
What is the corticospinal tract?
A patient has facial paralysis, dry eye, and dry mouth after a nerve injury. What is the primary nerve involved?
Damage to this nerve causes the tongue to deviate toward the side of the lesion

A patient speaks slowly and with great difficulty but understands what is being said. They are frustrated by their inability to communicate. What area is damaged?
What is Broca's area in the frontal lobe (inferior frontal gyrus)?
An elderly patient progressively becomes confused after a relatively minor head injury. Blood is accumulating between the dura and arachnoid. What vessel was most likely torn?
What are the bridging veins?
This structure is a single root extending from the conus medullaris and helps anchor the spinal cord inferiorly
