|
What part of the brain (general) does the anterior cerebral artery supply blood to? |
most of the medial wall, not including occipital lobe and inferior temporal lobe, which is supplied by posterior cerebral artery |
|
what does the anterior communicating artery do? |
joins the two anterior cerebral arteries |
|
What part of the brain (specific parts) does the anterior cerebral artery supply blood to? |
optic chiasm and hypothalamus lower extremeties part of anterior/posterior paracentral gyrus |
|
What bad thing is the anterior communicating artery most known for? |
aneurisms in the artery or where it joins the anterior cerebral arteries |
|
What is the paracentral gyrus |
This is the medial part of the pre/post central gyrus, so it's the part that is deeper in the brain |

What does M1 of the middle cerebral artery serve? |
temporal lobe-lenticulostriate arteries |
|
Superior and inferior trunks of MCA serve what? |
insular cortex and lateral surface of cerebral hemisphere |
|
What part of the brain (specific) does the MCA serve? |
lenticulostriate arteries insular cortex/lateral surface of cortex upper extremities of pre/post central gyri temporal gyri parietal lobe |
|
What part of the brain (specific) does the posterior cerebral artery serve? |
midbrain, diencephalon, posterior cerebral cortex |
|
What does the calcarine artery serve? |
primary visual cortex |
|
What does the vertebral artery serve? |
medulla, some cerebellum, and posterior dura |
|
What does the basilar artery serve? |
ventral and lateral cerebellum, pons, choroid plexus of fourth ventricle |
|
aneurism and where is it mostly found |
dilation of blood vessel; ballooning and explosion artery found at branch points of internal carotid arteries |
|
embolism |
clot |
|
alteriovenous malformations |

Describe, basically, the dural venous sinuses |
The layers surrounding the dura mater. They receive blood from veins of brain, CSF from subarachnoid space, and ultimately empty into internal jugular vein |
