Identify the bones and features indicated in this radiograph of the neck

I found this radiography online, i hope it's the same:

1 - Spinous process

2 - Atlas (it's the first vertebra)

3 - Axis (it's the second vertebra)

4 - Transverse process

5 - Intervertebral disc (present between vertebras)

6 - body of the vertebra

the occipital bone is a reference that it's the posterior side, while the mandibule indicates it's anterior.
