To allow passage of spinal nerves
The vertebra that does not have a body is the atlas, or the first cervical vertebra (C1). It supports the skull and allows for the nodding motion of the head. Instead of a typical vertebral body, the atlas has an anterior and posterior arch, facilitating its unique function in the spine.
Transitional lumbosacral vertebra is a condition where the last lumbar vertebra (L5) is partially fused with the first sacral vertebra (S1). This can lead to variations in the anatomy and function of the lower back and pelvis, potentially causing pain or discomfort. It is a common anatomical variant that may be seen in some individuals.
The function of the occipial condyle is to join the first cervical vertebra, (first bone on the neck), to enable the head to move relative to the neck.

The pedicles and laminae of a vertebra form the vertebral arch, which encases and protects the spinal cord. The pedicles are short, thick projections that extend backward from the vertebral body, while the laminae are flat plates that connect the pedicles to the spinous process. Together, they create an opening called the vertebral foramen, through which the spinal cord passes. This structure is essential for maintaining the integrity and function of the vertebral column.
The axis is the second cervical vertebra in the spine, located just below the atlas (the first cervical vertebra). It is named after its function as it allows the head to rotate on top of the spine.

Cervical vertebra
A kangaroo is a vertebra.
The seventh cervical vertebra is called as vertebra prominens. This vertebra has the long and prominent spine. This spine can be felt at the joint of the neck and thorax.
The c5 vertebra is located in the lower part of the neck, just below the c4 vertebra. The c4 vertebra is slightly higher up in the neck compared to the c5 vertebra.
