Ok so this is my something or the other PPT of the series dedicated to the Human Anatomy. The humor is mine. So just change it to fit your needs. Hope this helps.

Here we go…
Disclaimer: There are pictures in this
presentation you will not be able to find,
others you will. Make note of the
information and move on.

2. The Functions of BonesThe Functions of Bones
•Support
•Storage (Fat, minerals: Phosphorous,
Calcium)
*why is the calcium so important?
•Movement
•Protection
•Blood Cell Formation

3. Classification of BonesClassification of Bones

4. Classification: Bone ShapesClassification: Bone Shapes
Long Bones:Long Bones:
Femur, Tibia,
Fibula, Humerus,
Radius and Ulna
*What's wrong
with this bone?

10. Closer Look: Long BoneCloser Look: Long Bone
EpiphysisEpiphysis: Cartilage covers
both ends Contains Spongy
bone
DiaphysisDiaphysis (the shaft):
Composed of mainly compact
bone with a hollow cavity
Medullary CavityMedullary Cavity: Stores fat
and marrow that produces
blood cells
Yellow MarrowYellow Marrow: Fat storage
Red MarrowRed Marrow: Produces Blood
Cells stimulated by
Erythropoietin (EPO)

11. Closer look: DevelopmentCloser look: Development
Embryo:Embryo: Bone is
mainly Hyaline cartilage
Fetus:Fetus: Cartilage is
replaced with Bone.
Bone grows in lengths.
Child:Child: Cartilage is
mostly found on the
proximal and distal
ends. Bone grows in
Width. EpiphysealEpiphyseal
plateplate is still cartilage. What do you think happens to the
Epiphyseal plateEpiphyseal plate as an ADULT?

12. FracturesFractures
1)The bone is broken, blood vessels are ruptured
and a Hematoma (blood clot) forms
2) Fibrocartilage and spongy bone form with new
blood vessels growing into the area

13. FracturesFractures
3) Bone starts to replace the Fibrocartilage
and a Bony “Callus” is formed
4) Bone is “remodeled” due to stresses and
form a strong patch

14. FracturesFractures
Collar bone (clavicle) 3-8 weeks
Shoulder blade (scapula) 6
weeks
Ribs 4 weeks
Upper arm (Humerus) 4-10
weeks
Lower arm 6 weeks
Wrist 4-12 weeks
Fingers 4-6 weeks
Pelvis 4 - 6 weeks
Upper leg (femur) 12
weeks
Knee (patella) 4-6 weeks
Lower leg (tibia)10-24
weeks
Ankle 6 weeks
Foot3 - 12 weeks
Toes3 weeks

15. Types of fracturesTypes of fractures
Comminuted:Comminuted:
The Bone breaks into many
pieces
*Seen in the elderly due to
brittleness of bones*

16. Types of fracturesTypes of fractures
Compression:Compression:
Bone is
CRUSHED

17. Types of fracturesTypes of fractures
Depressed:Depressed:
Broken Bone portion
is pressed inward
What does that LOOK
like?

18. Types of fracturesTypes of fractures
Impacted:Impacted:
Broken bone ends are
forced into one
another

19. Types of fracturesTypes of fractures
Spiral:Spiral:
Bone is twisted
excessively and a ragged
break occurs
I found some videos of this
type of break but I didn’t
want anyone vomiting class.
Spiral:Spiral:
Bone is twisted

break occurs

20. Types of fracturesTypes of fractures
Greenstick:Greenstick:
Bone breaks incompletely
*common in children*
