Also known as cell, long up to 30cm depending on length of muscle. multi nucleate, packed full of myofibrils, packed full of mitochondria, 3or4 capillaries support each fibre
2 of 8
Actin
The thin protein filament found in the muscle cells that together with myosin form sarcomeres
3 of 8
Myosin
The thick protein filament that together with actin form sarcomeres, the contractile units of skeletal muscle
4 of 8
Sarcomere
the contractile units of skeletal muscle. They are composed of two myofilaments, actin and myosin.
5 of 8
myofibril
Any of the elongated contractile threads found in straight muscle cells
