Document Summary

Prime mover / agonist (has the major responsibility for a specific movement) Antagonist (opposes / reverses a specific movement: ex: b ceps brachii (flexor) vs. triceps brachii (extensor) Naming skeletal muscles: location (brachium = arm, shape (deltoid = triangular, relative size (maximus, minimus, longus, brevis) Skeletal muscle tissue: functions, movement, maintenance of posture, heat generation. Joint stabilization: characteristics, contractibility, excitability, extensibility, elasticity, types, skeletal. No striations, involuntary: similarities, muscle cells = fibers. Skeletal and smooth: myofilaments are responsible for contractibility of muscle tissue, plasma membrane called sarcolemma in muscle cells, cytoplasm called sarcoplasm in muscle cells, basics of skeletal muscle, epimysium, perimysium, fascicle (parallel groups of muscle fibers, endomysium. Nerves and blood vessels: rich blood supply due to high demand for oxygen and nutrients. Innervated (has input from the nervous system: muscle attachments, origin (muscle attachment to bone that remains stable)
