Atlas (C1) does not have a spinous process or body
The vertebral body is the most anterior part of a typical vertebrae. It is the weight-bearing portion of the vertebrae and serves as the main point of articulation with adjacent vertebrae in the spinal column.
The seventh cervical vertebra (C7) is known to have a forked spinous process making it easily distinguishable from the other cervical vertebrae. This unique feature is commonly referred to as the vertebra prominens.
The body of each vertebra is attached to a bony ring consisting of several parts. A bony projection on either side of the vertebral body called the pedicle supports the arch that protects the spinal canal. The laminae are the parts of the vertebrae that form the back of the bony arch that surrounds and covers the spinal canal. There is a transverse process on either side of the arch where some of the muscles of the spinal column attach to the vertebrae. The spinous process is the bony portion of the vertebral body that can be felt as a series of bumps in the center of a person's neck and back.
The vertebrae consist of the vertebral body, spinous process, transverse process, and articular processes. There are 33 vertebrae in total, including 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae (fused into the sacrum), and 4 coccygeal vertebrae (fused into the coccyx).
The spinous process is found on the posterior surface of most vertebrae.
Cervical vertebrae have a bifurcated spinous process.
The vertebral body is the most anterior part of a typical vertebrae. It is the weight-bearing portion of the vertebrae and serves as the main point of articulation with adjacent vertebrae in the spinal column.
That is likely a lumbar vertebra, which has a block-like body to support weight bearing and a short, stout spinous process for muscle attachment and stability. The lumbar vertebrae are larger and sturdier compared to other vertebrae in the spine to help support the lower back and trunk.

Spinous process
In the cervical spine, the C2-C6 vertebrae generally have bifid spinous proceses.
The Cervical vertebrae obtain: - Bifid (meaning double) spinous processes - Foramina transversarium for passage of nerves and vessels - The body is a more oval shape - Do not articuate with the ribs The Thoracic vertebrae obtain: - Spinous process (singular) - No foramina transversarium - The body is a small semi-circular shape - Articulate with the ribs -Have demifacets for articulation with the ribs The Lumbar vertebrae obtain: - Spinous process (singular) - No transverse processes - The body is a large circular shape - Does not articulate with the ribs - Demonstrates a "Scotty Dog" when positioned for a left/right anterior/posterior oblique radiograph.
the transverse process and the articular process also spinous process
