Muscles are a type of tissue composed of contractile cells or fibers that effect MOVEMENT of a part of the human body,that allows you to move your body...

Myosin protein helps move endorphins by binding to them and using energy to pull them along filaments in the body's cells.
Myosin makes up the THICK filaments, and actin makes up the thin filaments of myofibrils.
Actin and myosin
The thick protein filaments in a cell are primarily made of a protein called myosin. Myosin filaments are involved in muscle contraction and various other cellular processes such as cell motility and cytokinesis.
Repeating units of actin and myosin filaments are called sarcomeres. These are designed to control the contraction of muscles in the human body.
Myosin is responsible for actin-based muscular mobility/contraction.

Myosin
The release of ADP and P from the myosin heads causes the myosin heads to change shape.

ATP (adenosine triphosphate) is the main substance that causes the myosin head to change shape during muscle contraction. When ATP binds to the myosin head, it energizes the myosin molecule and allows it to detach from actin, resetting the myosin head for the next contraction cycle.
The two filaments involved are myosin and actin. Actin: is the framework and slides over the myosin filament when the muscle is shortened. myosin: is a thick filament Also a sacromere: is made up of the actin and myosin. It is the functional unit of a muscle fibre and extends from z line to z line. A muscle contraction: is many sacromeres shortening ( actin sliding over myosin)
