1. Bell Ringer: Number your paper from 1-12 and identify the bones in the back of the room from memory. Don’t look at your neighbor’s paper. How many bones are in the human body?

4. Introduction to The Skeletal System

5. Skeletal System Function: Protection: Organs Support: Framework Movement: Levers Storage: Fat and Minerals (calcium and phosphorus) How many Bones? 206 Skeletal System is divided into two categories: Appendicular Skeletal System Axial Skeletal System Osteology : (Osteo=bone) The study of the structure and function of the skeleton/bones

6. Axial Skeleton Function: Provides central support for body and protects internal organs Skull Ribcage Vertebrae

7. Appendicular Skeleton Function: Provides attachment points for muscles that allow movement. Limbs (arms/legs) Girdles (shoulder/pelvis)

8. BONE MARKINGS Every bump, groove, and hole has a name on your bones

9. Bone Markings Two types of bone markings: –Projections (processes) grow out from the bone Sites for muscle attachment Help to form joints

10. Bone Markings Two types of bone markings: –Depressions/Openings (cavities) that indent the bone Allows blood vessels and nerves to pass

11. Joint Projections 1) Condyle: Rounded articular projection Condyle

12. Joint Projections 2) Head: bony expansion on a narrow neck 3) Facet: smooth, nearly flat articular surface

13. Joint Projections 4) Ramus: Armlike bar of bone

14. Ligament/Tendon Projections 1) Crest: Narrow ridge of bone (Line: smaller than a crest) 2) Epicondyle: Raised area on or above a condyle ULNA

15. 3) Tubercle: Small rounded projection 4) Tuberosity: large rounded or roughened projection 5) Trochanter: very large, blunt projection (only on femur)

16. 6) Spine: Sharp, pointed projection Thoracic Vertebrae

17. DEPRESSIONS Allow blood vessels or nerves to pass through. 1) Meatus: (me - A- tus) Canal or tube

18. Depressions 2) Fossa: shallow basin 3) Fissure: narrow, slit- like opening

19. Depressions 4) Sinus: Cavity within a bone; filled with air and lined with mucous membranes 5) Foramen: Round or oval opening Foramen Magnum

20. Depressions 6) Sulcus, Groove or Furrow: a shallow depression
