Structure and Function of the Muscular System
The muscular system controls numerous functions, which is possible with the significant differentiation of muscle tissue morphology and ability.
Slow-Twitch and Fast-Twitch Muscle Fibers
Skeletal muscle contains different fibers which allow for both rapid short-term contractions and slower, repeatable long-term contractions.
Sliding Filament Model of Contraction
In the sliding filament model, the thick and thin filaments pass each other, shortening the sarcomere.
ATP and Muscle Contraction
ATP is critical for muscle contractions because it breaks the myosin-actin cross-bridge, freeing the myosin for the next contraction.
Control of Muscle Tension
Muscle tension is influenced by the number of cross-bridges that can be formed.
