Description
Skeletal muscle. Coloured transmission electron micrograph (TEM) of a longitudinal section through skeletal, or striated, muscle. The striations are due to the muscle fibrils, which run left to right. These are made up of the proteins actin and myosin. The lighter regions are stretches of actin, the darker regions are actin and myosin. Muscles contract when actin slides over the myosin. The energy for the contractions comes from mitochondria (purple). Skeletal muscle is under conscious control. Magnification x245 when printed at 10 centimetres wide.
