the cell volume we're not talking about a special

[lindapyburn]

The mostly the inside a muscle cell is all these my fibroblasts which are protein fibers so the Mile High Roller densely packed ride like elements they take up eighty percent of the cell volume we're not talking about a special I sell we talked about the specialized solar on okay so we knew you know how that carried out nerve impulses now we're going to talk about another specialized cell which is a muscle cell its role is to contract in order to do that it needs a lot of these my fibroblasts the omega my a5 reel exhibits try a shin perfectly aligned repeating Syria dark AB and in light IBM's and I do need you to connect dark in AB hands with light in IBM's and the way I do this is that the word dark hasn't a.m. EDT doesn't have FB1-Test an ID and the word light hasn’t I in its but it doesn't have any me and that's item right there so here's what we have look inside here this is the mile fiber I’ll in what you see is there's areas where there these thick filaments this is the Myerson big bands these red strike these red proteins going across here and then in this area you only have Indians and they haven't shown you those yet okay we're going to magnify it so you can see that there is a in protein here so this area creation and our plan bill she knew this area right he recreates the light beams and remember the dark bands are called-bands the light beams a call idea so what you see when you look at an entire muscle fiber is series on dark light dark light dark light because ask these mile fiber of fit in the cytoplasm the pica filaments are all lined up here then there's might be an the entire diameter dick then the then the been am I am I a ton that's what causes the striations see you.
