WebThis is an actual muscle cell and so let's zoom in on the actual muscle. So let me actually draw it really a lot bigger here. So an actual muscle cell is called a myofiber. It's called a fiber because it's longer than it is wide and they come in various-- let me draw the myofiber like this. I'll take a cross section of the muscle cell as well. WebStriated muscles are defined as muscles that can contract and relax independently. They are classified as the type of muscle that is in parallel with each other since they all contract at the same time, but they can also contract at different times. In a striated muscle, it is possible to see the individual fibres of the muscle running along ...
