Using this image, summarize the basic structures of the muscular system. Include Muscles, tendons, connective tissue and Key components: muscle fibers, myotibrils, sarcomeres

9.2 Structure of a Skeletal Muscle Connective Tissue of Muscles Skeletal Muscles: Connective tissue coverings over skeletal muscles: . Over 600 skeletal muscles in the body . Fascia: Thin covering of connective tissue around a Skeletal Muscle Fibers muscle . Attached to bones, and skin of face Skeletal muscle fiber (cell): . Tendon: Cord-like mass of connective tissue that Multinucleated . Under conscious control (voluntary) connects muscle to a bone Sarcolemma: Cell membrane of muscle fiber . Aponeurosis: Sheet-like mass of connective tissue that . Are organs of the muscular system connects a muscle to bone, skin, or another muscle Sarcoplasm: Cytoplasm of muscle fiber Connective tissue in and closely surrounding a muscle, Many myofibrils: Skeletal muscles are composed of: together makes a tendon: . Long, parallel structures that run down fiber . Skeletal muscle tissue . Epimysium: surrounds whole muscle; lies beneath fascia . Consist of thin filaments (actin) and thick filaments (myosin) . Nervous tissue Perimysium: surrounds fascicles within a muscle. . Sarcomeres: Units that connect end-to-end, to make up myofibrils Endomysium: surrounds muscle fibers (cells) within a Sarcoplasmic reticulum (SR): Endoplasmic reticulum of muscle . Connective tissues, including Blood fascicle stores calcium
