Follow the pathway that allows a nerve signal initiated in the brain to induce an actual muscle contraction in a skeletal muscle. Myosin ATPase is going to help hydrolyze, meaning it will break down ATP. The major functions of muscle tissue are movement: body, parts, blood, and food; maintenance of posture (skeletal muscle); joint stability: shoulder/knee (skeletal); heat production-85% (skeletal). There is an increased number of myofibrils per cell. depolarization of sarcolemma causes increased cytoplasmic ca2+ from SR (via GPCR) and extracellular fluid (via voltage-gated channel). When ATP is broken down you get ADP and inorganic phosphate.
