1. Ch. 5 Bone LT: List the functions of the skeletal system
Name the four main kinds of bones
Identify the anatomical areas of a long bone
ET: Grab a copy of the article at the front. Think about the following questions:
What do bones do?
What do we already know about them?

2. Functions of Bones Support – Bones for the internal framework
Protection – Keep soft organs protected (Brain)
Movement – Muscles are attached by tendons to allow body movement
Storage – Stores fat and minerals (Ca+)
Blood cell formation – Red blood cell are made from red bone marrow (Hematopoiesis)

3. Classification Long – longer than they are wide
Short – Cube shaped and mostly spongy
Flat – Thin, Flat, and Curved
Irregular – Bones that do not fit the above categories

4. Diaphysis: Shaft
Periosteum: Membrane connected by Sharpey’s fibers
Epiphyses: Ends
Articular Cartilage (hyaline)
Yellow marrow or medullary cavity: Fat

5. Classification
Spongy
Compact

6. The Bone ET: Define the following terms LT: Today I will..
Ossification
Osteoblast (bone + germinate)
Osteoclast (bone + broken)
Osteocyte
LT: Today I will..
Describe briefly the process of bone formation in the fetus
Summarize the events of bone remodeling
Name and describe the various types of fractures

7. Compact (wall of the diaphysis)
Types of Bone Tissue
Compact (wall of the diaphysis)
Spongy (cancellous, epiphysis) - red marrow

8. Medullary Cavity – hollow chamber filled with bone marrow
Inside the Long Bone
Medullary Cavity – hollow chamber filled with bone marrow
Red Marrow (blood)
Yellow Marrow (fat)
Endosteum
– lining of the medullary

10. Microscopic Structure – Write this down
MATRIX - where the bone cells live
OSTEOCYTES  - mature bone cells, enclosed in tiny chambers called LACUNAE
OSTEOCYTES form rings (LAMELLAE) around a HAVERSIAN CANAL which houses blood vessels
Osteocytes are linked by CANALICULI
Haversian Canals are linked by VOLKMAN's CANALS

11. Osteocytes
Haversian Canal
Volkmann’s Canal

16. Chicken Cemetery FQ: What makes up the bone matrix?
List a few things you already know about the bone cell matrix (2 min.)

17. Bone Remodeling and Classification
On your blaster/claster wheel, use the key and label the types of cells at each numbered step (wedge of the wheel)
Cut out your top wheel and attach it to the bottom wheel
Start at step one, and in your own words describe what is happening at each step

18. Bone Remodeling - Explained
Get your skin model from the back – keep it or throw it away after you leave this room
Take out your blaster/claster wheel and your list of descriptions for each step
Compare your list with two other people from different groups (5 min.)

19. Bone Cells

20. Ossification – Bone formation
Osteoblast cover a cartilage model of the bone with bone matrix
The matrix will absorb mineral salts and harden and be come compact bone
Remodeling

21. Get You Chicken Bones Complete the analysis questions
What is being lost from the bone?

22. Forensic Science Learning objective:
To learn and become a forensic scientist
Apply your forensic knowledge and identify bones at a crime scene

23. Agenda Bone Fractures Look at bone fractures
Go over the wound healing process

24. 8 Types of fractures Simple Compound Comminuted Compression Depression
Impacted
Spiral
Greenstick

25. Healing A Bone Fracture
Hematoma – blood filled swelling
Bony Callus – osteoblast and osteoclast replace the fibrous callus with spongy bone
Fibrocartilage Callus – various cells create cartilage, bone matrix, and collagen fibers
Bone remodeling

26. Gross Anatomy of Bones
Create detailed, labeled drawing of the each different specimen (be careful there are duplicates)
Try and see as much of the long bone anatomy as possible and identify the different parts
Your drawing will be turned in at the end of the period
