The lateral masses
Occipital condayles
Connected by the anterior and posterior arch
What does the IAP articulate with?
The SAP of C2
Describe the Transverse process of the Atlas
contains the transverse foramen
What is the purpose of the transverse foramen
The vertebral artery runs through the TVF on its way to the brain for supply of blood brain
What makes the Atlas atypical
It has no body nor spinous process
What is the C2 known as ?
The Axis
The axis
C2
What is the function of. the Axis
Transmits the load of the head and the atlas to other cerbical vertebrae
Where does the body of the axis sit?
underneath the dens
Anotehr word for the dens
Odontiod process
Where does the Dens come from
embryonically the body of C1
Describe the postion of the dens
projects superioly from the body of c2
How does the dens articuale anteriorly?
Anterior arch
How does the dens articualte posteriorly
with the Transverse ligament
describe the Spinous process of the Axis
large and bifid
Describe the articular processes
They lie on an oblique plane
What does the SAP articulate with
