Today we are going to look at the sarcomere.
00:03
We are going to start from the muscle and zoom into the individual units of a muscle, which is the sarcomere.
00:11
So as we can see here, it starts from the muscle and then goes on to the muscle fiber bundle, then which goes on to the muscle fiber here, and then to the myofibos and the myofilaments, which is the sarcomere.
00:28
So just to repeat, the muscle fiber goes to the myofibyls and then the myofilaments, which is the same thing as a cellophon.
00:40
So let's focus on attention over here now.
00:44
This is a muscle fiber, which is the same thing as a muscle cell.
00:48
And obviously we can see here in mitochondria because we need atp.
00:53
We can see the cycloplasm, which is a cytoplasm in the muscle fibers.
01:00
We can see the cycloplasmic reticolin here.
01:03
Which stores and releases calcium ions, which is obviously very necessary for muscle contraction...
