Question 4

muscle function

Question 5

muscle structure

Answer 5

muscle fibres– myofibril– myofilaments

Question 6

sliding filament theory

Answer 6

occurs within sarcomete
requires calcium and ATP
nervous system causes the myosin head to attach to actin forming cross bridge, myosin head pivot and pull actin towards of sarcomere, process is repeated and myosin attaches further along the actin
