All but humans
The atlas is the uppermost vertebrae in the neck.
the first 7 vertebrae, the neck vertebrae, are considered to be cervical
Vertebrae are divided into sections: the atlas and axis account for the first cervical vertebrae, of which there are 7 in total; there are 12 thoracic vertebrae, 7 lumbar vertebrae, 1 sacrum (5 separate vertebrae in a baby), and 1 coccyx (4 separate vertebrae in a baby).
No, all of the vertebrae in the spine have names. In addition to the first two vertebrae (C1 and C2), the other vertebrae are named based on their location: cervical (C3-C7), thoracic (T1-T12), lumbar (L1-L5), sacral (S1-S5), and coccygeal (Co1-Co4).

First seven vertrebrae. Develps an anterior curvature. Labeled C1 to C7. Supports the weight of the head. First two vertebrae have special names.
The uppermost vertebrae is called the atlas. It is the first cervical vertebra located at the top of the spine, just below the skull. It is named after the Greek Titan Atlas, who held up the celestial spheres.
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.
Gliding joints are found between vertebrae except for the first two which have a pivoit joint.
T1 and T2 refer to the first and second thoraxic vertebrae. They are the 8th and 9th vertebrae, starting from the top.
The cervical spine is made up of seven cervical vertebrae. These are numbered(C1-C7) and are the smallest of the true vertebrae. The third through sixth cervical vertebrae have characteristics in common. The first, second, and seventh are considered special cervical vertebrae, and have different characteristics.
