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, and cell nuclei (orange). Each myofibril is surrounded by sarcoplasmic reticulum (white). The picture was created as part of a cooperation with Quintessenz Publishing. Magnification: x3000 when printed at 15cm wide. | |
