Lecture 11 Flashcards
Superficial cerebral veins
Drain cortex and adjacent white matter
Empty into superior sagittal sinus or sinuses near the inferior cerebrum
Deep cerebral veins
Drain the basal ganglia, diencephalon, and adjacent white matter
Empty into the straight sinus
Subarachnoid Hemorrhage
Bleeding into the arachnoid space
Due to trauma like shaking
Difficult to stop: arterial; high pressure
Anterior spinal artery supplies
Medulla
Anterior inferior cerebellar artery and superior cerebellar artery comes from
Basilar artery
Posterior inferior cerebellar artery comes from
Vertebral artery
Anterior spinal artery clot results in
Motor loss
Posterior spinal arteries clot results in
Sensory loss. It also depends on which posterior spinal artery is damaged cause there is a R and L
Vasa nervorum
blood supply to peripheral nerves
Blood-brain barrier
Permeability barrier between the capillaries of the CNS and the extracellular space
Formation of BBB
Formed by tight junctions between endothelial cells of the capillaries
The BBB is absent in which parts of the brain?
Hypothalamus and third and fourth ventricles. this leads to vulnerability of infection in these areas
If you have a headache, what type of vascular disorder to you most likely have?
subarachnoid hemorrhage
If you have posterior neck pain, what type of vascular disorder to you most likely have?
vertebral artery dissection
If you have Limb ataxia and weakness, dysfunction of cranial nerve, what type of vascular disorder to you most likely have?
Basilar artery ischemia
