4
Q
What is the difference between C-1 and C-2 and what movements do they do
A
- C-1 Atlas:
- Has no body or spinous process
- holds weight of head
- widest of the cervical vertebra due to ransverse process extending further
- MOVEMENTS:
- Flexion and extension
- small rotation
- C-2 Axis:
- MOVEMENT: Side to side
5
Q
What do the Thoracic vertebra do? And a difference between these vertebra and the others
A
- Extra stabilzed due to attachment to the Ribs
- Carries large portion of upper body
- Larger Spinous process
6
Q
What do the vertebra in the lumbar spine do?
A
- Largest vertebra in the spine
- Carries large portion of upper body weight
