Let's tackle this question by dividing this group of cells into supporting cells for the cns and supporting cells for the pns.
00:14
Remember, the cns is the central nervous system.
00:18
It is made of the brain and spinal cord.
00:21
The pns, remember, is the peripheral nervous system.
00:26
It is made of everything else inside the human nervous system, except.
00:30
The brain and spinal cord.
00:33
The central nervous system has several kinds of supporting cells.
00:38
The first cns supporting cell we're going to talk about is called an astrocyte.
00:44
It is called an astro site because it looks like a star, which is what astro means, cell.
00:53
An astro site is responsible for helping with the exchange that occurs between, the neurons and the blood capillaries.
01:13
The second kind of cns supporting cell that we have are the ependymal cells.
01:24
Epidymal cells are responsible for lining the central cavities called ventricles of the brain and spinal cord.
01:53
The third kind of cns supporting cell that we have are the micro gael cells.
02:05
Micro means small...
