6.3 Neuroglial Cells Flashcards
1
Q
Saltatory conduction
A
Increases velocity of AP, forces it to jump (diffusing) steps
2
Q
Schwann cells
A
Peripheral Nervous system support cells
3
Q
Oligodendrocytes
A
Central nervous system support glial cells(can wrap around several axons at once)
4
Q
Schwann cells filled with
A
Lipid called myelin (forming myelin sheath)
5
Q
Myelin sheath prohibits
A
Diffusion in or out, no AP except before or after
6
Q
Grey matter in brain consists of
A
Unmyelinated neurons (processing)
7
Q
White matter in brain consists of
A
Myelinated neurons (wiring)
8
Q
Astrocyte
A
Star like shape, manager of nerves
Release growth factors, help repair, metabolism, protection, form blood brain barrier
