Flashcards in functional neuroanatomy Deck (4)
1

cortical blood supply
where? + what?

1) Anterior cerebral artery (frontal)
2) Middle cerebral artery
3) posterior cerebral artery (posterior)
- The arteries deliver oxygenated blood, glucose and other nutrients to the brain, and the veins carry deoxygenated blood back to the heart, removing carbon dioxide, lactic acid, and other metabolic products

2

the circle of Willis

- connects the anterior and posterior cerebral circulations
- Provides backup circulation to the brain in case a supply artery is blocked
- providing blood to tissues that would otherwise become ischemic (allows for collateral circulation)

3

Meninges

- Dura mater lays under the skull; hard matter
- Arachonid layer -
- Pia mater (adheres closely to the brain)
- Subarachnoid space - CSF

4

2 types of stroke

Isimatic stroke - No blood going through the artery

Haemorrhaging stroke - artery inside your brain bursts causing bleeding within your brain
