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.
Ch. 7
SKELETAL BONES
206 total bones in the adult
body
Children – around 450
* due to some bones not yet fused
EX: - wrist
- ankle
- pelvis
- skull
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
2 Major Skeletal regions:
1. AXIAL – head neck and torso (80)
2. APPENDICULAR – arms and legs (126)
AXIAL
SKULL – 28 bones total
Cranium (8)
Face (14)
Ear (6)
SKULL FEATURES
SUTURES – immovable joints between skull
bones
SINUS – cavity or space
MEATUS – tube-shaped opening
FORAMEN – hole (for blood vessels)
* foramen magnum – hole at bottom of
skull, where spinal cord attaches to brain.
PROCESS – projection (sticking out)
