Coloured scanning electron micrograph (SEM) of a muscle fibre. Muscles fibres are formed of many myofibrils (red), the basic protein unit of a muscle cell. Within the muscle fibre are mitochondria (blue), which provide energy. Each myofibril is surrounded by sarcoplasmic reticulum (white). The picture was created as part of a cooperation with Quintessenz Publishing. Magnification: x20, 000 when printed at 15cm wide. | |
