Neuropathophysiology

1. components of a -cell body
neuron -dendrites
-axon
2. cell body contains organelles
3. dendrites receive signals and conduct them to cell body; increases surface area of the neuron
4. axon generates and conducts action potentials
5. aging process this natural process includes the loss of neurons without replenishment as mature
neurons don't divide
6. brain & spinal neurons in this area are not remyelinated after injury and cannot regenerate axons
cord
7. gray matter includes cells bodies; makes up majority of cerebrum

8. white matter includes myelinated axons; located deep within the cerebrum
9. chromatolysis swelling of a neuron in response to injury, eventually ruptures
10. neuronophagia dead nerves cells are digested by phagocytes and aggregation of inflammatory
cells protects myelin/remaining nerves
11. intraneuronal in- aggregation of proteins in a neuron resulting from viral encephalitides
clusions
12. glial cells cells in the nervous system that support, nourish, and protect neurons; their major
role is responding to nerve injury
13. fibrillary astro- located within white matter, they are prone to neoplastic transformation -->
cytes gliomas
14. oligodendroglia myelin producing cells that act in the CNS when young and PNS thereafter
-in gray matter they surround neurons
-in white matter they are arranged longitudinally along myelinated fibers
15. ependyma single layer of cells lining the ventricles of the brain and spinal cord canal; it
facilitates fluid transfer
