Your skeletal muscles are made up of bunches of elongated, rod-shaped cells called muscle fibres. Each of your muscle cells is packed full of thinner fibres called myofibrils. These fibres contain ...

Atomic images of muscle molecules in action have now been captured by researchers, giving possibility of new nanomachines. At the molecular level, muscle contraction is defined by myosin molecules ...

The film discusses the intricate relationship between muscles and bones, highlighting the mechanics of body movement. It explains how muscles work by contracting and relaxing in coordination with ...

Beet juice boosts endurance for many (but not all) people, according to a series of studies over the past five years or so. The active ingredient appears to be nitrate, which somehow reduces the ...

Much like their name implies, the quadricep muscles were once thought to be a set of four muscles, with the name “quad” translating to “four or fourth” in Latin. However, it has since been discovered ...
