Muscle tissues and skeletal muscle
Every movement you make, from a blink to a sprint, depends on cells that can pull. This topic compares the three muscle tissues, then takes a skeletal muscle apart layer by layer, down to the repeating units that shorten and the signal that tells them when to start.
