common carotid a
external carotid a.
internal carotid a
Blood supply to the brain left side
common carotid a.
external carotid a.
internal carotid a.
what is the vertebral arteries
Posterior, pass through foramen magnum + Join to form the basilar artery
which artery turns 90 degress
Internal Carotid Artery (90 degree): Anterior part
Branch from the common carotid AA,
Enter the skull via the carotid canals in the petrous part of the temporal bone
what artery branch serves the medial region of the frontal and parietal lobes
Anterior cerebral
what artery branch serves the lateral surface of most of the cerebral hemispheres
middle cerebral
what artery branches serve the medial region of the cerebral hemispheres and occipital lobe
posterior cerebral artery
what are the communicating arteries of the brain
anterior communicating artery
posterior communicating artery
basilar
blood supply to the brainstem
Basilar artery
pontine artery
cerebella artery : superifical, anterior inferior, posterior inferior
sinuses in the brain
Sagittal Sinuses – sup + inf
Straight Sinus
Transverse sinus
Confluence of Sinus
Cavernous sinuses
describe the straight sinus
Junction of Flax cerebi and tentorium cerebelli
Joins inferior and superior sagittal sinuses
descibe the transverse sinus
Formed by tentorium cerebelli
describe the confluence of sinus
Junction point of straight, superior, sagittal and transverse sinuses
describe the cavernous sinus
Paired, Plexus – walled veins
