Using the following terms, describe the overall structure and organization of a skeletal muscle: muscle, fascicle, muscle fiber, myofibril, sarcomere, myofilament, epimysium, perimysium, endomysium. Would you consider a skeletal muscle to be highly organized? If so, what helps to maintain this organization? What is responsible for the striated appearance of skeletal muscle tissue? Conclude your description with a response to the following statement: The presence of connective tissue sheaths facilitates movement when skeletal muscles are stimulated to contract. Explain
