1 Muscular System Review

2 Origin and Insertion

3 Parts of a Muscle muscle fiber, fascicle, endomysium, perimysium, epimysium, tendon

4 Tendon vs Aponeurosis

5 Name a muscle … Shape Origin and insertion Relative size
Directions of fibers Action Body region

6 Let’s give it a try… Latissimus DORSI TRANSVERSUS abdominis
ADDUCTOR longus GLUTEUS maximus ORBICULARIS oris Rectus FEMORIS STERNOCLEIDOMASTOID

7 Muscle contraction

8 Sacromere Dance 1. Ca+ causes change in SARCOLEMMA
2. Distracts chaperone (troponin) 3. boy ACTIN bad, grabs Myosin 4. drags her to the middle of the dance floor

9 Terms Sarcolemma Sarcomere Fiber Fascicle myoglobin

10 Motor Unit

11 Smooth or Striated Voluntary or Involuntary location

12 Slow Twitch vs Fast Twitch

13 SLOW vs FAST RED in color Lighter Slow contraction fast
Slow fatigue easily tired High myoglobin low High mitochondria low

14 Isotonic vs Isometric

15 Antagonistic vs synergistic

16 Tetany vs Tone

17 Muscle Fatigue

18 Muscle Cramp-sustained contraction or overshortening

19 Rigor Mortis
