during contraction of a skeletal muscle? Calcium is an important element for live. Calcium is found in the bones of animals and humans. In muscle contraction is produce as a result of Calcium ions ‚ Ca2+‚ It comes from rapid release from the cisternae of the sarcoplasmic reticulum which cause a chemical reaction between ATP and the myofilaments.

how muscles contract‚ this is shown by the 5 stages of the sliding filament theory. When the muscle contracts‚ the myosin filaments attach themselves to similar actin filaments‚ this attachment causes formation in chemical bonds this then forms the cross bridges. Myosin and actin molecules are made in a series‚ this series is what makes up a muscle cell. This basic module is called the sarcomere‚ these are what gives the tissue of a skeletal muscle its appearance. The mechanism within muscle contraction

Muscle Fiber contractions for our purposes begins with the arrival of action potential (action potential- is an electrical current) at the end of the axon terminal (axon terminal- the swollen distal end of the motor neuron axon). When the action potential reaches the axon terminal the action potential causes the voltage- gated calcium ion channels to open allowing calcium to flow in from extracellular fluid.
