Intervertebral discs
The articulations of the human skull and vertebral column consist of a series of amphiarthrodial joints between the vertebral bodies, and a series of diathrodial joints between the vertebral arches. The articulations of the rat skull and vertebral column consist of cervical vertebrae which have small, transverse processes containing a hole through which nerves and blood vessels pass.
The joints between the vertebrae of the backbone are called intervertebral joints. These joints are formed by the articulation of the vertebral bodies and the intervertebral discs, which help provide stability, flexibility, and cushioning to the spine.
Vertebral end plates are the top and bottom portions of the vertebral bodies that interface with the vertebral discs. The vertebral end plate is composed of a layer of thickened cancellous (spongy) bone.
The joint type that includes the joints between the vertebral bodies is a cartilaginous joint called an intervertebral disc joint. The joint type that includes the joints forming the pubic symphysis is a cartilaginous joint called a symphysis joint.
The anterior longitudinal ligament of the vertebral column acts to limit hyperextension of the spine and provide stability to the vertebral column by connecting and supporting the anterior aspect of the vertebral bodies.
The facet joints are the joints between adjacent vertebrae.
Intervertebral disc separates adjacent vertebral bodies.
- Transverse foramen (holes in the transverse processes through which travels the vertebral artery) - Uncinate processes (lip on the supero-lateral aspects of vertebral bodies)
The lumbosacral junction is located in the lower center of the back and between the hips. It consists of the L5 vertebral and the first sacral vertebral body.

No. "Backbone" is a common name for the spinal/vertebral column. Intervertebral disks are the the pieces of cartilage found between the individual vertebral bones in the column/backbone.
