Name that cranial nerve
This nerve abducts the eye
What is CN VI (Abducens)?
An ACA stroke primarily affects motor and sensory function in this part of the body
What is the lower extremity?
These are the three meninges in order, from superficial to deep
This pathway carries vibration, fine touch, and proprioception
Which cranial nerve provides motor innervation to the muscles of mastication?
What is CN V3 (Mandibular branch of the trigeminal nerve)?
This nerve innervates the Superior Oblique
What is CN IV (Trochlear)?
An MCA stroke primarily affects this region of the body
What are the face and upper extremity?
Blood accumulating between the skull and the Dura mater is called what?
What is an epidural hematoma?
A lumbar puncture is typically performed at this vertebral level to avoid damaging the spinal cord
What is L4-L5?
This muscle is responsible for depressing the eyebrows
What is Corrugator Supercilli?
Damage to this nerve causes hoarseness and difficulty swallowing
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
What is CN XII (Hypoglossal)?
A patient speaks fluently, but their speech consists of nonsense words and they cannot understand commands. What type of aphasia is this?
A crescent shaped collection of blood that crosses the suture lines is most characteristic of what?
What is a subdural hematoma?

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
What is the filum terminale?
A patient has severe, stabbing facial pain triggered by lightly touching their cheek. There is no facial paralysis. What is the most likely diagnosis?
