Answer: The correct order of the levels of organization from smallest to largest is molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, biosphere. In a muscle myofilaments are arranged in bundles called myofibrils which in turn are bundles in a fascicle and many such fascicles make up a muscle.And the muscle is covered by the perimysium, the fascicle is covered by the epimysium,the myofibrils are enclosed by the endomysium and finally the myofilament are enclosed by the sarcolemma. Greater maximal shortening velocity due to longer fascicle length would allow greater force output at an identical shortening velocity.

The major differences between these two muscle types are that the cardiac muscle cells are branched and are held together by intercalated disks. smaller than a myofibril. Each arrangement has its own range of motion and ability to do work. } Fascicles can be parallel, circular, convergent, pennate, fusiform, or triangular. How is the molecular organization of muscle cells? Muscle fibers are typically large cells, some 20100 m in diameter and many centimeters long, with the longest fibers being about 12 cm. Black Adam Kills Superman, There are about 600 muscles in the human body. Fascicle arrangement is correlated to the force generated by a muscle and affects the muscles range of motion. The smallest contractile unit of skeletal muscle is the muscle fiber or myofiber, which is a long cylindrical cell that contains many nuclei, mitochondria, and sarcomeres (Figure 1) [58].
