7. 3 Types of Muscle

8. Smooth Muscle-lines organs, digestive tract, respiratory tract- involuntary

9. 3 Types of Muscle Smooth Muscle Cardiac Muscle-heart muscle-involuntary

10. 3 Types of Muscle Smooth Muscle Cardiac Muscle Skeletal Muscle- voluntary

11. Antagonistic relationship What is the definition of antagonistic?

12. Antagonistic relationship Skeletal muscles work in pairs.

13. Antagonistic relationship Skeletal muscles work in pairs. The pairs work in opposition to each other.

14. Example: biceps and triceps When one muscle contracts the other relaxes

15. There are over 600 skeletal muscles in the human body, they all have a name.

16. There are 7 ways muscles are named

17. 7 ways Muscles are named 1. Origin and Insertion- where the muscle begins and end. Example- sternocleidomastoid

18. 7 ways Muscles are named 1. Origin and Insertion- where the muscle begins and end. Example- sternocleidomastoid 2. Action- what the muscle does. Example- flexor Carpi

19. 7 ways Muscles are named 1. Origin and Insertion- where the muscle begins and end. Example- sternocleidomastoid 2. Action- what the muscle does. Example- flexor Carpi 3. Location- Example- pectoralis major, when there is a major muscle there is always a minor, pectoralis minor

20. 7 ways Muscles are named 4. Fiber Direction- example: obliques

21. 7 ways Muscles are named 4. Fiber Direction- example: obliques 5. Number of divisions- example: biceps, triceps

22. 7 ways Muscles are named 4. Fiber Direction- example: obliques 5. Number of divisions- example: biceps, triceps 6. Size- example: Gluteus Maximus. When there is a maximus there is always medius and minimus

23. 7 ways Muscles are named 4. Fiber Direction- example: obliques 5. Number of divisions- example: biceps, triceps 6. Size- example: Gluteus Maximus. When there is a maximus there is always medius and minimus 7. Shape- Example: deltoid

24. Range of Motion Each joint and the muscles that move the joint have a specific range they can move.

25. ROM’s Flexion- bending a joint Extension- straightening a joint example: elbows and knees

26. ROM’s Flexion and extension- example: elbows and knees Abduction-moving a body part away from the body Adduction-moving a body part toward the body example: moving the legs or arms outward or inward

27. ROM’s Flexion and extension- example: elbows and knees Abduction and adduction-example: moving the legs or arms outward or inward Pronation- turning the palms down. Supination-turning the palms upward. Example: turning the palms of the hand up or down

28. ROM’s Flexion and extension- example: elbows and knees Abduction and adduction-example: moving the legs or arms outward or inward Pronation and supination-example: turning the palms of the hand up or down Rotation-movement around the axis of the joint.

29. Flexion and extension- example: elbows and knees Abduction and adduction-example: moving the legs or arms outward or inward Pronation and supination-example: turning the palms of the hand up or down Rotation-movement around the axis of the joint. Circumduction- movement at the end of the rotating body part
