"The lymphatic vessels within the skeletal muscle do not have any contractile properties and thus depend on the inherent contractility of the skeletal muscle and arteriolar pulsations. Lymphatic drainage originates from lymph capillaries within the endomysium merging into smaller lymphatic vessels that pass through the perimysium connecting to larger vessels."

"Myocytes consist of myofibrils composed of sarcomeres, that feature the basic contractile properties of muscle and are the simplest functional unit of the myofibrils 1. Microscopically the arrangement of sarcomeres creates a striated or striped appearance, which can be seen in skeletal and cardiac muscles and contribute to their classification 1. Sarcomeres consist of thick and thin filaments composed of different proteins, namely myosin (thick filaments), actin, troponin and tropomyosin (thin filaments) and are arranged parallel to the muscle fibre axis 1-3."
