From whole muscle to sarcomere

From whole muscle to sarcomere

Skeletal muscle organisation from whole muscle to sarcomere with labelled tendon, fascicle, muscle fibre, myofibrils, actin and myosin, plus slow-twitch and fast-twitch comparison Skeletal muscle is voluntary and usually pulls on bones through tendons. A whole muscle is made of fascicles, each fascicle contains many muscle fibres, and each muscle fibre contains many myofibrils.
