name a factor that affects the amount of tension produced when a skeletal muscle contracts
the length of individual sarcomere
explain two key concepts of the length-tension relationship
the greater the zone of overlap in sarcomere the greater the tension the muscle can develop, there is an optimum range of actin and myosin overlap that will produce the greatest amount of tension
for each portion of a myogram tracing a twitch in a stimulated gastrocnmeius muscle fiber, describe the events that occur within the muscle
first the latent period than contraction phase and finally relaxation phase
