Introduction to Skeletal Muscle

The muscular system controls numerous functions, which is possible with the significant differentiation of muscle tissue morphology and ability. 

Skeletal muscle contains different fibers which allow for both rapid short-term contractions and slower, repeatable long-term contractions.

In the sliding filament model, the thick and thin filaments pass each other, shortening the sarcomere.

ATP is critical for muscle contractions because it breaks the myosin-actin cross-bridge, freeing the myosin for the next contraction.

Muscle tension is influenced by the number of cross-bridges that can be formed.
