whats the purple arrow pointing to

transverse foramina

What specific cervical vertebrae is this and why

C1 The atlas, no body or spinous process

What specific cervical vertebrae is this and why

C2 the Axis, the bump sticking off the body called the dens

How does C2 and C1 work together

allow rotation of the head
