Muscles stretched beyond this point will produce less tension. If the muscle is at its resting length it will not produce maximal tension because the actin and myosin filaments excessively overlap.

WebSkeletal muscles do not work by themselves. Muscles are arranged in pairs based on their functions. For muscles attached to the bones of the skeleton, the connection determines the force, speed, and range of movement. These characteristics depend on each other and can explain the general organization of the muscular and skeletal systems.

WebIn some muscles, the largest motor units may generate a contractile force of 50 times more than the smallest motor units in the muscle.
