1. The Skeletal System

2. I. The Skeletal System A.List and define the 2 types of bone tissue. http://kidshealth.org/PageManager.jsp?lic= 1&article_set=54029&cat_id=20607

3. I. The Skeletal System A.List and define the 2 types of bone tissue. 1.Compact bone: 2.Spongy bone:

4. I. The Skeletal System A.List and define the 2 types of bone tissue. 1.Compact bone: functions as supportive tissue. 2.Spongy bone: less dense calcium network

5. I. The Skeletal System B.Where are the 2 types of bone tissue found? 1.Compact bone: outside most bones. 2.Spongy bone: inside bones, ends of long bones, most short bones.

6. I. The Skeletal System C. Define cartilage and its purpose. flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the bronchial tubes and the intervertebral discs.bones Cartilage acts as a cushion between the bones.

7. I. The Skeletal System D. Define ligaments and their purpose. fibrous tissue that connects bones to other bones Ligaments hold the bones of many joints together.

8. II. The Skeleton A.Color and label the axial skeleton and appendicular skeleton B.Define the axial skeleton and give examples of bones from this section C.Define the appendicular skeleton and give examples of bones from this section.

9. II. The Skeleton B.Define the axial skeleton : Provides structure and protects some organs. EX: Skull, ribs, spinal column, pelvis C.Define the appendicular skeleton: allows movement. EX: Shoulder, arms, legs.

10. D. List the 4 changes the skeleton makes. 1.Infancy 2.Childhood 3.Adolescence 4.Adulthood

11. E. Describe what happens at each stage. 1. Infancy: spaces between bones in skull close. 2. Childhood: growth occurs at bone plates 3. Adolescence: at end of adolescence, bones stop growing. 4. Adulthood: old bone broken down and new bone formed

12. F. Joints of the Human Body Open Sciencesaurus to 086 and complete the chart. Joint TypeWhere FoundMovementExample

13. F. Joints of the Human Body Joint TypeWhere FoundMovementExample Pivot Neck, elbowBones rotate around each other Gliding Wrist, ankle, vertebrae Bones slide over each other HingeKnee, elbow, fingers, toes Back-and- forth Ball-and- socket Shoulders, hips Rotational or circular

14. The Muscular System http://kidshealth.org/PageManager.jsp?lic=1&article_set=540 40&cat_id=20607

15. I. The Muscular System A. List the 3 functions that muscles perform. 1.Movement 2.Maintaining body temperature 3.Maintaining posture

16. I. The Muscular System B. Define homeostasis. Process that organism maintains internal conditions needed for health and functioning.

17. I. The Muscular System C. Why is homeostasis important? Because we need to maintain the correct body temperature

18. I. The Muscular System Open Sciencesaurus to 087 and answer D, E, F, and G. D. List the 3 types of muscles and where each type of muscle is found. E. Which muscle is voluntary and which muscle is involuntary? F. What attaches skeletal muscles to bone? G. How do muscles produce movement?

19. I. The Muscular System D. List the 3 types of muscles and where each type of muscle is found. 1.Skeletal muscles: attached to bones 2.Smooth muscles: found inside some organs. 3.Cardiac muscle: heart

20. I. The Muscular System E. Which muscle is voluntary and which muscle is involuntary? 1.Voluntary: skeletal. 2.Involuntary: smooth and cardiac.

21. I. The Muscular System F. What attaches skeletal muscles to bone? –tendons G. How do muscles produce movement? –Skeletal muscles act in pairs. When one contracts, the other relaxes, and vice versa.

22. I. The Muscular System H. What do skeletal muscles have to do as infants and adolescences grow? –Develop and strengthen. I. What is the relationship between exercise and muscles? –When you exercise regularly, your muscles get bigger.
