Q

What is dura mater?

A

Brain covering with an outer periosteal layer and an inner meningeal layer

potential epidural space on top (under neurocranium) and potential subdural space below (above arachnoid layer)

Q

What are arachnoid granulations?

A

Smaller arachnoid villi that project from the arachnoid into the superior sagittal sinus. They allow for reabsorption of CSF from the subarachnoid space into the venous system.

Q

A 45yo woman presents after an episode of sudden inability to speak. She also reports occasional word finding difficulties over several months as well as headaches when she wakes up in the morning. Which of the following is the most likely etiology:

a) left-sided meningeoma compressing inferior frontal gyrus
b) left-sided meningeoma compressing the posterior superior temporal gyrus
c) left-sided meningeoma compressing the superior parietal lobule

A

a) left-sided meningeoma compressing inferior frontal gyrus

the problem is with broca’s area, which is located in the inferior frontal gyrus

Q

A 63 yo man with a history of htn, hld, and dmII presents with acute onset of weakness and numbness of the right face and arm, global aphasia, and left gaze palsy. He is able to life his right leg. A stroke due to the occlusion of what artery might cause these symptoms?

a) left anterior cerebral artery
b) left middle cerebral artery
c) basilar artery

A

b) left middle cerebral artery

occlusion of the middle cerebral artery will cause upper limb and face symptoms because it supplies the lateral part of the motor homunculus

A 25yo man is brought by ambulance after a high-speed car accident. He was not wearing a seatbelt. He requires significant stimulation to open his eyes, only mumbles incoherently, and has significant weakness throughout the right side.

a) left middle cerebral artery branches
b) cortical bridging veins
c) circle of Willis

250
Q

What is the function of layer V of the cerebral cortex?
