muscle contraction
A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.
Fueling Muscle Contraction
ATP is the immediate source of energy for muscle contraction. Although a muscle fiber contains only enough ATP to power a few twitches, its ATP "pool" is replenished as needed.

Control of Muscle Contraction
Neuromuscular junctions are the point where a motor neuron attaches to a muscle. Acetylcholine is released from the axon end of the nerve cell when a nerve impulse reaches the junction.
The contractile ring that produces cell cleavage is composed of an organized cytoskeletal network that includes actin and bipolar myosin-II filaments working together in a sliding action that mimics muscle contraction.
Microfilaments' association with the protein myosin is responsible for muscle contraction. Microfilaments can also carry out cellular movements including gliding, contraction, and cytokinesis.

Ca2+ is used in a multitude of processes, among them muscle contraction, release of neurotransmitter from nerve endings, vision in retina cells, proliferation, secretion, cytoskeleton management, cell motion , gene expression and metabolism.
Actin filaments are important in muscle contraction.
During cell division a ring of actin filaments that surrounds the cell constricts, pinching the cell into two.

Minerals are trace elements required for normal metabolism, as components of cells and tissues, and for nerve conduction and muscle contraction. They can only be obtained from the diet.

Actin filament (AK-tin) Part of the cytoskeleton. Actin filaments contract or lengthen to give cells the flexibility to move and change shape. Together with myosin, actin filaments are responsible for muscle contraction.
Creatine phosphate (phosphocreatine) In muscle, a compound with a high phosphoryl transfer potential that is used to regenerate ATP from ADP during the initial seconds of muscle contraction.
The establishment of electric potentials across the plasma membrane and across organelle membranes makes possible a number of phenomena, including the chemiosmotic synthesis of ATP, the conduction of nerve impulses, and muscle contraction.
