2
5
6
The A band contains
actin filaments only
myosin filaments only
both myosin and actin filaments
neither myosin nor actin filaments
When a muscle contracts
both actin and myosin become shorter in length
myosin heads pull the actin towards the M line
actin heads pull myosin towards H line
the sarcomere length increases
