What is the structure of the Atlas (C1)?
Consists of anterior and posterior arches, without a vertebral body, connected by the transverse process.
What unique feature does the Axis (C2) have?
The odontoid process (or dens), which is embryologically the vertebral body of the atlas (C1).
What are the key requirements for assessing the Atlas?
Anterior arch, posterior arch.
What are the key requirements for assessing the Axis?
Dens, transverse foramen.
What is the transverse foramen?
An opening in cervical vertebrae occupied by the vertebral artery and vein.
