1. SKELETAL SYSTEM pp

2. Starter List as many joints in the body as you can
Describe how each joint moves
Make groups of joints based on their similar movement

3. FUNCTION Bones support and protect organs and muscles
Gives shape and structure
Store minerals
Produce blood cells

4. SKELETON
Axial –the skull, face, vertebral column, and rib cage (80 bones)

5. SKELETON Appendicular –the arms and legs, pelvis, scapula, etc
(126 bones)

6. BONE STRUCTURE Porous and made of proteins and minerals
osteocytes –cells that make bone
bone marrow – soft bone tissue that produces blood cells

7. BONE DEVELOPMENT Develop from cartilage
ossification: hardening of bone cartilage
Elongation at end of bones

8. JOINTS
place where two bones meet

9. Associated Connective Tissue
Ligaments: connects bone to bone
(tough bands that hold joint in place)
Tendons: connect muscle to bone
Cartilage: flexible connective tissue

10. Disease of the Connective Tissues!

12. JOINTS
Fixed: no movement between bones (ex. skull).

13. JOINTS
Semimovable: limited movement (i.e. rib cage and vertebrae)

14. JOINTS Movable hinge – moves up and down (ex. knee and elbow)
pivot – move side to side (ex. skull joins the vertebral column)
ball-and-socket – move in a circle (ex. Shoulder)

15. JOINTS
Movable
gliding – bones slide over one another (ex. Ankle and wrist)
Saddle- rotate and grasp (ex. Base of thumb)
