The Muscular System
Gross Anatomy of Skeletal Musclebundle of muscle fibers muscle fiber (cell) myofibril sarcomere
Connective Tissue SheathsEndomysium Perimysium Epimysium Collagen fibers of all 3 layers come together at each end of muscle to form a tendon or aponeurosis.
Basic Features Nerve & blood supply Attachments Origin Insertion
Muscle Fiber Anatomy Sarcolemma Sarcoplasm MyoglobinTransverse tubules (T-tubules) Myofibrils Myofilaments Two types Actin filaments (thin filaments) Myosin filaments (thick filaments)

1. What are the three types of muscles found in the muscular system A. Skeletal, cardiac, muscle fibers B. Skeletal, cardiac, smooth C. Skeletal, smooth,
Muscle Fibers. Muscle fiber is the muscle cell Each skeletal muscle contains hundreds to thousands of these fiber cells.
Muscular System. Classification Red vs. White Somatic vs. Visceral –Move bones or cartilages vs. organs, vessels, and ducts. Voluntary vs. Involuntary.
