1. WARM UP 1/20 1. How many bones do we have in our body?
2. How many in our head?
3. Name as many bones as you know.

2. Ch. 7 : 1/30
Intro to BONES: skull

3. 206 total bones in the adult body
Children – around 450
* due to some bones not yet fused
EX: - wrist
- ankle
- pelvis
- skull

4. CHILD’s SKULL
Fontanels – areas where the major skull bones have not fused together yet
AKA “soft spots”
Purpose: so skull can be flexible for birth
(solid after about 18 months)

5. 2 Major Skeletal regions:
1. AXIAL – head neck and torso (80)
2. APPENDICULAR – arms and legs (126)

6. AXIAL
SKULL – 28 bones total
Cranium (8)
Face (14)
Ear (6)

7. SKULL FEATURES SUTURES – immovable joints between skull bones
SINUS – cavity or space
MEATUS – tube-shaped opening

8. FORAMEN – hole (for blood vessels)
* foramen magnum – hole at bottom of skull, where spinal cord attaches to brain.
PROCESS – projection (sticking out)
