Cranial System Flashcards
Falx cerebri
seperates the left and right hemispheres
tentorium cerebelli
seperates the cerebrum and cerebellum
the venous sinuses ___
contain venous blood from the brain and skull
Venous sinuses of importance
- superior sagittal sinus
- inferior sagittal sinus
- straight sinus
- transverse sinus
- confluence sinus
- sigmoid sinus
Arteries that supply the brain
- internal carotid artery
- vertebral artery
the internal carotid artery gives rise to
the anterior circulation
the vertebral arteries give rise to
the posterior circulation
blood circulation of the brain occurs in 3 types of pathways
- anterior cerebral
- middle cerebral
- posterior cerebral
the most common type of stroke is
ischemic stroke
ischemic stroke is a
clot blocking blood flow to an area of the brain
hemorrhagic stroke is a
bleeding inside or around brain tissue
clinical outcome of stroke rules
- laterality
- location
- lef-sided language representation
- cortical mapping
laterality rule
each side of the brain governs movement and sensation on the opposite side of the body
location rule
each vessel supplies a specific portion of the cerebral cortex
left sided language representation rule
language is represented in the left cerebral hemisphere
