1. NEUROMUSCULAR SYSTEM

2. MUSCULAR SYSTEM Anterior Posterior

3. MUSCULAR SYSTEM Smooth Muscle Cardiac Muscle Skeletal Muscle

4. MUSCULAR SYSTEM Smooth Muscle Found in the digestive, circulatory, urinary and reproductive systems Controlled by the autonomic nervous system Smooth in appearance Involuntary controlled

6. Contraction of the heart is controlled by the sinoatrial node (SAN)

7. Striated in appearance

9. Controlled by the somatic nervous system

10. Striated in appearance

12. SLIDING FILAMENT THEORY myosin actin myosin cross-bridges attach to the actin filaments actin is pulled together and sarcomere length is reduced

14. NEUROLOGICAL SYSTEM The Central Nervous System The Brain and Spinal Cord The Peripheral Nervous System

15. THE REFLEX ARC Central Nervous System Sensory Receptor Sensory Nerve Motor Nerve Muscle responds to nerve impulses

17. The more muscle units that are recruited for a task, the greater the force will be developed

19. Antagonist- The opposing muscle that relaxes in order to allow the movement to occur

20. Synergist- A muscle that assists the agonist in producing movement

23. Eccentric (negative); the muscle contracts and lengthens to control a resistance

24. Isometric (static); the muscle contracts to overcome a resistance but without any change in length

26. Large myoglobin content

27. Many mitochondria

28. Many capillaries

30. MUSCLE FIBRE TYPE ACTIVITIES- Maintaining posture Endurance-based activities

32. Smaller myoglobin content

33. Fewer mitochondria

34. Fewer capillaries

36. Produce more force

37. Short term contractions

41. Increase in the diameter of the recruited fibres
