Cervical
The atlas and axis are among the cervical vertebrae.
The atlas is the uppermost vertebrae in the neck.
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.
It's the first cervical vertebra located just beneath the skull
There are 33 Vertebrae, starting from the top (just under skull) there are: 7 cervical vertebrae 12 thoracic vertebrae 5 lumbar vertebrae 5 sacral vertebrae (fused together) 4 coccygeal vertebrae (fused together)
There are seven cervical (C1-C7) vertebrae. The top two are unique in form and number three through seven are similar in morphology. The uppermost is the atlas (C1) which supports the skull, and the next is the axis (C2), where much if the rotation takes place. The body of the atlas is the odontoid process of the axis (c2), and the atlas (c1) rotates around this.
The T3 vertebra is located in the thoracic region of the spine, specifically between the T2 and T4 vertebrae. It is one of the twelve vertebrae in the thoracic spine and is positioned below the T2 vertebra and above the T4 vertebra.
The thoracic vertebrae are found in the chest region of the body. Humans have twelve thoracic vertebrae which are located between the cervical and lumbar vertebrae.
The vertebrae as a whole are considered irregular bones.
The L2-L3 vertebrae are located in the lower back, specifically in the lumbar region. They are the second and third vertebrae from the top of the lumbar spine, just below the L1-L2 vertebrae and above the L3-L4 vertebrae.
The vertebrae nearest the abdominal region are the thoracic vertebrae.
