The dens or odontoid process.
The second vertebrae has a dens (meaning tooth) which sticks up into the ring made by the atlas (the first vertebra). The head can pivot with this type of joint. A person can nod the head "no".
around the dens of the second vertebra. Is that is the full question?
odontoid process
Vertebrae are categorized by where they are located. The top 7 are called cervical vertebrae (neck), the next 12 are thoracic vertebrae (chest), and the last 5 are lumbar vertebrae (back).
The vertebrae in the neck are called cervicle vertebrae. There are 6 of them altogether. The first two (going downward from the skull) are called the atlas and the axis. The rest are just name by their order. Eg: C1 (Atlas), C2 (Axis), C3, C4.....

T1 and T2 refer to the first and second thoraxic vertebrae. They are the 8th and 9th vertebrae, starting from the top.
The name of the second vertebrae is called the axis.
The first vertebrae is called The Atlas.The second is the Axis, which allows the neck/head to pivot(turn).
The first and second cervical vertebrae form the atlantoaxial joint. These bones are known as the atlas and the axis.
intervertebral discs are not found in the sacrum and coccyx, where the vertebrae have fused, or between the first and second cervical vertebrae.
You have 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumber vertebrae, 1 sacrum and 1 coccyx. The first cervical vertebra is called as atlas vertebra. The second one is called as axis vertebra.
The first vertebrae is called The Atlas.The second is the Axis, which allows the neck/head to pivot(turn).
