Okay, so why don't we go through and label a few components? i have this muscle fiber cell drawn out here, and so we'll just go through the components one by one.
00:11
So, you know, to start off, we have our sarcolemma.
00:14
This is the plasma membrane equivalent of the specialized muscle cells.
00:19
So sarcolemma, right? we know that the sarcolemma feeds down into our t system, composed of t -tubules.
00:30
That's what you see in green here.
00:31
You see those little cylinders penetrating down into the cell.
00:35
In green we have our t -tubules.
00:41
And next to the t -tubules, we have our sarcoplasmic reticulum.
00:45
It's kind of this network that holds calcium ions for us.
00:49
So sarcoplasmic reticulum.
00:58
Charcoplasmic reticulum.
00:59
All right...
