sliding filament theory
Give this one a try later!
1. thin filamentsslide toward M lin, alongside thick filaments
2. width of A zone remains the same
3. Z lines move closer together
,__ phase of a twitch, Ca+ levels fall, active sites are covered, tension falls to resting
levels

relaxation
max tension development or peak of tension is btw __ and __ phase of twitch
Give this one a try later!
btw contraction and relaxation phases
__ is when the body needs mor O2 than usual to normalize metab. activities
