In 1954, two researchers, Jean Hanson and Hugh Huxley from the Massachusetts Institute of Technology, made a model for muscle tissue contraction which is known as the sliding filament theory. This theory describes the way a muscle cell contracts or shortens as a whole by the sliding of thin filaments over thick filaments and pulling the Z discs behind them....


It is the explanation for how muscles produce force. in order to slide past one another the myosin heads will interact with the actin filament ,and using atp, bend to pull past the actin

thanks can you explain in brief
Muscle is a specialized contractile tissue that is a distinguishing characteristic of animals. Changes in muscle length support an exquisite array of animal movements, from the dexterity of octopus tentacles and peristaltic waves of Aplysia feet to the precise coordination of linebackers and ballerinas. Its the sliding filament theory.
Sliding filament theory in its simplest form states that muscle fibres shorten when actin filaments slide inward on myosin filaments - pulling the z-lines closer together.If that's all Greek to you then have a quick look at the article on muscle anatomy which outlines the different components of a muscle.
