Special Selective Vulnerabilities Flashcards
1
Q
what components are at risk for damage from brain contusions? why?
A
orbital and temporal regions b/c of irregularities of adjacent inner surfaces
2
Q
what components are at risk from ischemia? why?
A
neurons in CA1 of the hippocampus and Purkinje cells of the cerebellum due to their high concentration of glutamate receptors (which makes them prone to excitotoxicity)
3
Q
what components are at risk from CO intoxication? why?
A
globus pallidus and substantia nigra; due to high concentration of iron containing substances with a high affinity for CO
4
Q
what area is at high risk from methanol? chronic ethanol?
A
putamen and anterior cerebellar vermis (reasons unknown)
