Vertebrae are the individual bones that make up the vertebral column, or spine, providing structural support and protecting the spinal cord. Each vertebra typically consists of a vertebral body, a vertebral arch, and various processes for muscle attachment and articulation with adjacent vertebrae. They are categorized into different regions: cervical, thoracic, lumbar, sacral, and coccygeal, each with unique shapes and functions. Additionally, vertebrae contain intervertebral discs that act as shock absorbers and allow for flexibility and movement of the spine.
Thoracic vertebrae are between the cervical vertebrae and the lumbar vertebrae. The ones farther down the spine are larger. They have facets on the sides of the bodies for articulation with the heads of the ribs.

The tuatara has a spinal column with vertebrae, which is the defining characteristic of a vertebrate.
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).
General features of bones are called bony prominences and are used to locate muscles in the body.
the thoracic spine is above the lumbar spine which means ALL thoracic vertebrae are superior to the lumbar vertebrae.

The five types of vertebra are the:cervical vertebrae (neck)thoracic vertebrae (chest)lumbar vertebrae (back)sacral (pelvis)coccyx (tailbone)

Cervical vertebrae can be identified by their distinct features: they are smaller and have a unique structure with transverse foramina in the transverse processes, which allow for the passage of vertebral arteries. The first two cervical vertebrae, the atlas (C1) and axis (C2), have specialized shapes that enable pivotal head movements. Additionally, cervical vertebrae typically have a bifid spinous process, except for C7, which has a longer, non-bifid spinous process.
The total number of bones depends entirely on the type and size of the snake. In general, snakes have sectioned vertebrae (backbones) with ball and socket joints between sections of vertebrae that allow for curving motion. They also have anywhere from one to 145 pairs of ribs attached to the vertebrae, and a skull with a hinged jaw.
