WebDec 21, 2024 · The structure of the sarcomere is traditionally described with dark and light bands visible under the microscope. This banding pattern in sarcomeres is due mainly to the arrangement of thick and thin myofilaments in each unit. These markings include: A bands (or anisotropic bands) - dark bands that contain whole thick filaments (myosin). 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. cibc housing forecast
