Communicating arteries Flashcard Deck - 10 Cards

Flashcard 1: Which vessel of the Circle of Willis arises from the terminal bifurcation of the basilar artery?

Answer: Posterior cerebral artery

Extra: The posterior cerebral artery (PCA) arises from the terminal bifurcation of the basilar artery. It supplies the occipital lobe and the inferior portion of the temporal lobe. It is connected to the internal carotid artery via the posterior communicating artery, completing the posterior part of the Circle of Willis.

Flashcard 2: Saccular aneurysms of the _____ communicating artery may cause compression of the CN III

Answer: posterior

Flashcard 3: Which artery in the Circle of Willis supplies the medial aspect of the frontal and parietal lobes?

Answer: Anterior cerebral artery (ACA)

Flashcard 4: Saccular aneurysms of the _____ communicating artery may cause compression of the optic chiasm

Answer: anterior

Flashcard 5: What structure is most commonly compressed by an aneurysm of the anterior communicating artery?

Answer: Optic chiasm compression, resulting in bitemporal hemianopia.

Extra: Aneurysms of the anterior communicating artery (ACom) are the most common site of Berry aneurysms in the Circle of Willis. Due to their location, they can compress the optic chiasm, leading to visual field defects.

Flashcard 6: An aneurysm of which artery is most commonly associated with a CN III palsy?

Answer: CN III (Oculomotor nerve) palsy

Extra: Aneurysms of the posterior communicating artery (PCoA) typically cause a CN III palsy with pupil involvement (mydriasis), because the parasympathetic fibers are superficial on the nerve. Findings: Ptosis, "down and out" eye position, and a dilated pupil.

Flashcard 7: Where do saccular "berry" aneurysms tend to occur?

Answer: bifurcations in Circle of Willis; especially anterior and posterior communicating arteries

Flashcard 8: Identify the branch of the vertebral artery labeled as number 3 in the provided image.

Answer: posterior spinal arteries

Flashcard 9: Identify the artery in the vertebrobasilar system labeled as number 9 (the vessel formed by the union of branches from both vertebral arteries descending the spinal cord):

Answer: Anterior spinal artery

Extra: The anterior spinal artery is formed by the union of two small branches from the vertebral arteries. It descends in the anterior median fissure and supplies the anterior two-thirds of the spinal cord.

Flashcard 10: anterior cerebral artery (ACA)

Answer: medial motor cortex, medial sensory cortex

Extra: leg paralysis and sensory loss
