arterial supply to the blood Flashcards
what vessels does the circle of willis involve
internal carotid, middle cerebral artery, posterior communicating artery, posterior cerebral artery
how is the basilar artery formed
by the fusion of two vertebral arteries
what are anterior cerebral branches joined by
anterior communicating arteries
what are posterior cerebral branches join up
the internal carotid and the basilar artery
where does he internal carotid originate from and where does it enter the brain
bifurcations of common carotid and carotid canal
what branches does the internal carotid artery give rise to
- Ophthalmic artery
- Posterior communicating artery
- Anterior choroidal artery
- Anterior cerebral artery
- Continues as middle cerebral artery
what is arterial blockage
arterial blockage is when a cerebral artery is blocked in the Brian it is most likely o occur in middle cerebral artery than the anterior cerebral artery as it more continuous with the internal carotid - if there is blockage in the posterior cerebral artery = blurry vision
where does the ventral artery enter the cranial and what does it branch off as
enters at the foramen magnum, then branches as meningeal, anterior and posterior spinal arteries and the posterior inferior cerebellar artery
what happens after the vertbral artery branches
2 vertebral arteries converge to form basilar artery
what does the vertebral artery arise form
the subclavian arteries
wha is osteoarthritis
bony projections that occur in the small face joints of cervical spine - if in neck can cause dizzy when turning head - caused by osteophytes
what does the anterior cerebral artery supply
blood to the lower limb region of the motor cortex and the anterior brain
what does the middle cerebral artery supply
head and neck and upper limb and trunk regions of the motor cortex and middle brain
what does the posterior cerebral artery supply
posterior brain
