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.
Yes, calcium is necessary for the release of neurotransmitters that cause a muscle to initiate a contraction. Calcium is also needed to bind to the troponin-tropomyosin comple â¦ x causing it to change position so the myosin head can attach to the actin molecule which results in contraction.alcium is also needed to bind to the troponin-tropomyosin comple â¦ x causing it to change position so the myosin head can attach to the actin molecule which results in contraction.
