Definition of muscle in English:

muscle

noun

  • 1A band or bundle of fibrous tissue in a human or animal body that has the ability to contract, producing movement in or maintaining the position of parts of the body.

    Muscles are formed of bands, sheets, or columns of elongated cells (or fibres) containing interlocking parallel arrays of the proteins actin and myosin. Projections on the myosin molecules respond to chemical signals by forming and reforming chemical bonds to the actin, so that the filaments move past each other and interlock more deeply. This converts chemical energy into the mechanical force of contraction, and also generates heat
