1. neuronal injury involves dam- neurons
age to the?
2. neuronal injuries can be irreversible (lead to cell death) or reversible
________ or _________?
3. what are some common stres- -ischemia / hypoxia
sors that can cause neuronal -infectious agents
injury? -chemicals
-autoimmune
-pressure/force
4. what are the 2 types of cell apoptosis and necrosis
death?
5. what is the difference between -apoptosis: organized, ordered, systematic, uses ATP, smaller
apoptosis and necrosis? immune response
-necrosis: not organized, irreversible injury, contents dumped
into extracellular space (can damage other surrounding cells)
6. what type of cell death is apoptosis
known as cell suicide?
7. what can occur to neuronal in- neurons can have structural changes to their processes (den-
jury morphology? drites and axons)
8. what glia cells are involved in astrocytes and microglia
neuronal injury?
9. what are astrocytes primarily gliosis ---- repair and scar formation
responsible for?
10. they undergo hypertrophy and hyperplasia (during gliosis)

cytes are considered "reactive
astrocytes"?
11. what are microglia? resident immune cells of CNS
12. at sites of neuronal injury, inflammatory process & tissue repair
microglia will be involved In
what?

14. how does opioids most com- opioids --> suppress respirations = no gas exchange --> no
monly cause overdose death? blood to brain
15. what is cerebral edema? accumulation of excess fluid in the brain parenchyma
