Verified step by step guidance1
Begin by understanding the structure of muscle tissue. Muscle tissue is composed of muscle fibers, which are the basic cellular units.
Each muscle fiber contains smaller structures called myofibrils. Myofibrils are the contractile elements within the muscle fiber.
Myofibrils are composed of repeating units called sarcomeres, which are responsible for muscle contraction.
Fascicles are bundles of muscle fibers, not the smaller structures within the fibers themselves.
Tendons are connective tissues that attach muscles to bones, not components within muscle fibers.
