Thank you for the opportunity to help you with your question!

Muscle Fibres: Long, multinucleated cells found in skeletal muscles; containing approximately one thousand contracting myofibrils. They are specialized, contracting cells that are bundled together to form muscles

Myofibrils: Tubular organelles found in muscle fibers that appear striated under a microscope, they are contractile fibers in muscle tissue. They are found lying within skeletal muscle fibers that are composed of repeating structural units called sarcomeres.
