Each of these contain which are the primary intracellular structure (cylindarshaped) which make up the and contain thick protein filaments called and thin protein filaments called . Myosin filament contains globular heads called Answer: skeletal muscle is made up of many fascicles, which contain muscle fibers or muscle cells that are multinucleated. Each of these contain myofibrils which are the primary intracellular structure (cylindar shaped) which make up the sarcomere and contain thick protein filaments called myosin and thin protein filaments called actin. Myosin contains globular heads callcross bridges. Endomysium=wraps each individual muscle fibre.Perimysium = wraps fasicles. Epimysium = wraps the whole muscle. 2. Average sarcomere size Answer: 2.2 microns 3. The sarcoplasmic reticulum contains invaginationscalled which function to: Answer: t tubules allow action potential across surface of cell into the cell or myofibril 4. Sarcomere arrangment: I bands= A bands= Z line or disc=H zone= M Line= Answer: I bands= actin, thin filaments A bands= myosin filaments and part of actin that overlaps (thick)Z line or disc= connect 1 sarcomere to another H zone=contains myosin only M Line=through center of H zone.Contains proteinsto hold gother myosin molecules 5. 16 step sequence of events for muscle contraction to occur. Excitation contraction/sliding filament theory Answer: 1. m and h gates open 2. Sodium influx into nerve cell
