Understand the hierarchical structure of skeletal muscle, which is organized from the smallest to the largest components: myofilaments, myofibrils, muscle fibers (cells), fascicles, and the whole muscle.
Recall that a muscle fiber (or muscle cell) is surrounded by a connective tissue layer called the endomysium.
Recognize that a group or bundle of muscle fibers is surrounded by another connective tissue layer called the perimysium.
Identify that this bundle of muscle fibers surrounded by perimysium is called a fascicle.
Differentiate the other terms: a sarcomere is the functional contractile unit within a myofibril, a tendon connects muscle to bone, and a myofibril is a subunit within a muscle fiber composed of sarcomeres.
