1. Directions: OPEN YOUR YELLOW FOLDERS and complete the table. Do Now: Identifying and Classify Bones of the Skeletal System

2. Directions: Read and annotate. Reading: Treating a Broken Bone

3. Directions: Examine the diagram about bone healing and formation. Use the word bank to fill in the blanks. Notes: Bones Healing and Repair

4. Notes: Bone Healing and Repair Directions: Take notes in your science notebook. https://www.youtube.com/watch?v=rlesSq8m8JE YOUR OPINION– Answer in complete sentences! Discuss with your lab group! How does bone tissue repair (regenerate) after a fracture? Use the following anatomical structures in your answer; blood vessels, spongy bone, compact bone, osteocytes

6. Long Bone Structure review Directions: READ ONLY … This is review. You already have these notes!

7. Long Bone Structure review 1.Shaft is known as the diaphysis. 2.Consists of a thick collar of compact bone surrounding a central marrow cavity 3.Expanded ends are epiphysis 4.Thin layer of compact bone covering an interior of spongy bone.

8. Periosteum review 1.The external surface of the entire bone except for the joint surfaces of the epiphysis is covered by a double-layered membrane known as the periosteum.

9. Bone Cells Osteocytes review

10. Notes: Bone Healing and Repair 1.Bone cells at the site (place) of the fracture become deprived (loss) of nutrients and bone cells die. The site becomes swollen, painful, and inflamed. 2.White blood cells (WBC also known as macrophages) begin to clean up all the debris (waste, dead cells). 3.Osteoblasts begin to form spongy bone. 4.This callus (like on your fingers if you play guitar, or on your heel from friction) splints the broken bone.

11. 5. More spongy bone is formed in about 6-8 weeks. Notes: Bone Healing and Repair 6. Osteoclasts work to remove the temporary supportive structures while osteoblasts rebuild the compact bone and reconstruct the bone so it returns to its original shape and structure.

12. Bone Healing and Repair – flow chart Checking for Understanding: Draw a flow chart. Draw 6 boxes (or circles, triangles, etc.) to show the 6 steps of bone fracture healing and repair.

13. End of the Skeletal System Congratulations! You have now completed all the objectives and standards of the skeletal system! 1.AP 2.1 Explain the anatomical position and the terms that describe relative positions, body planes, and body regions. Describe the body cavities and the organs within each cavity; the major organ systems; and their role in the functioning of the body. 2.AP 2.2 Distinguish bones according to shape and describe the major functions of bone. Describe the structure of a typical long bone and indicate how each part functions in the physiology and growth of the bone. 3.AP 2.3 Describe the types of cells found in bone and their role in bone growth and control of bone mass. 4.AP 2.4 Distinguish the axial from the appendicular skeleton, and name the major bones of each. Locate and identify the bones and the major features of the bones that make up the skull, vertebral column, thoracic cage, pectoral girdle, upper limb, pelvic girdle, and lower limb.
