One of hundreds of thousands of cylindrical subunits that make up a skeletal muscle cell.
|
Myofibrils
|
|
|
Protein that, along with myosin, is the chief component of muscle; makes up the thin filament of a muscle fibre.
|
Actin
|
|
|
Protein that, along with actin, is the chief component of muscle; makes up the thick filament of a muscle fibre.
|
Myosin
|
|
|
A high-energy compound that regenerates ATP in muscle cells.
|
Creatine Phosphate
|
|
|
Muscle fibre that produces most of its energy aerobically; contracts slowly, but can maintain a steady, prolonged production of ATP when oxygen is available.
|
Slow-Twitch Fibres
|
|
|
Muscle fibre that produces most of its energy anaerobically; adapted for the rapid generation of power, but dependence on anaerobically produced energy results in vulnerability to accumulation of lactate, causing rapid fatigue.
|
Fast-Twitch Fibres
|
