Six major cell types found in nervous system
|
neuron, neuroglia, astrocyte, microglia, ependymal cell, oligondendrocytes
|
|
Neuron-->primary fxn, CNS or PNS
|
transmits impulses to and from CNS. Both CNS and PNS
|
|
Neuroglia-->primary fxn and location
|
provide a supportive scaffolding for neurons. CNS
|
|
Astrocytes-->primary fxn and location
|
support and brace neurons. CNS
|
|
Microglia-->primary fxn and location
|
monitor health of neurons. CNS
|
|
Ependymal cells-->primary fxn and location
|
circulate CSF (CNS)
|
|
Oligodendrocytes-->primary fxn and location
|
wrap CNS axons in myelin sheath..
|
|
Schwann cell-->primary fxn and location
|
surround axons of PNS in myelin sheath
|
|
Satellite cells-->primary fxn and location
|
surround neuron cell bodies (PNS)
|
|
Define myelin sheath, it's fxn, and importance
|
white, fatty sheath protects long axons
electrically insulates fibers increases speed of nerve impulses |
|
Describe neurilemma
|
remaining nucleus and cytoplasm of a Schwann cell
|
