1. TOPIC: Locomotion Aim: Explain the structure and functions of the 3 types of muscles. Do Now: Explain the difference between a ligament and a tendon. HW: Castle Learning – Skeletal and Muscular System

2. Identify the purple structures in the diagram. Explain their function.

3. Babies are born without the patella (knee bone) it develops between ages 2 and 5.

4. Did you know……………. You have over 30 facial muscles which create looks like surprise, happiness, sadness, and frowning. Eye muscles are the busiest muscles in the body. Scientists estimate they may move more than 100,000 times a day! The largest muscle in the body is the gluteus maximus muscle in the buttocks.

5. Function of the muscular system Locomotion Move by contracting (shortening) and relaxing

6. Voluntary muscles You are able to control

7. –Examples: Arm & leg muscles

8. You do not control consciously Involuntary Muscles

9. –Example: Heart and stomach muscles

10. MUSCLES TYPES

11. Non-striated (no stripes) Involuntary Smooth Muscle

14. Line your internal organs (digestive system, blood vessels…)

15. Cardiac Muscle ONLY in the HEART Involuntary

16. Striated (have stripes) Fibers branch

18. Skeletal Muscle Attached to bones Voluntary

19. Striated

21. Work in pairs. –One contracts while the other relaxes

24. How do muscle cells get energy? Aerobic respiration (needs oxygen)

25. Glucose + Energy Oxygen Carbon Dioxide Water + +

29. Let’s summarize… 1.Identify the 3 types of muscles. 2.Describe where each type of muscle is located. 3.Describe whether each type of muscle is involuntary or involuntary. 4.Describe whether each type of muscle is striated or non-striated.

30. Review: Identify the muscle being described. 1.Involuntary 2.Striated 3.Found in the heart 4.Lines internal organs 5.Voluntary 6.Branched fibers 7.Attached to bones
