Secondly, applied research, which is the application of basic research to understanding how behaviour can be changed in everyday setting. When applied research is conducted using samples that are representative of the population to demonstrate effective behaviour change it is particularly relevant to policy makers.
Making the world better, one answer at a time. During skeletal muscle contraction calcium ions expose myosin binding sites on to the actin. When a nerve sends a signal to a muscle to do some action the release of acetylcholine at the neuromuscular junction triggers calcium to be released into the cytoplasm. At rest, the cell has a low concentration of calcium.
Magnesium ions found in the fluid surrounding the cells generate a small electrical charge in response to the calcium ions and propels the calcium ions back across the calcium sensitive potassium pump in the cell membrane. This stimulates potassium ions to flow out of the cell, which produces muscle cell relaxation.
