Are there vertebral discs in the sacrum?
No. There are no intervertebral discs in the Sacrum. The Sacrum is a fusion between 5 vertebrae and this the same with the Coccyx (fusion of 3). The final intervertebral disc is between L5 and the superior surface of the Sacrum.
What superior articular process of the sacrum articulate?
The superior articular process of the sacrum articulates with the inferior articular process of the last lumbar vertebra (L5) to form the lumbosacral joint.
How do the superior and inferior articular process of the atlas differ from the same processes on a typical vertebra?
The surface of the superior articular will work right above the inferior surface in a vertebra. This is not true in the atlas.
Referring to the skull what is the atlas?
It is the the most superior (first) cervical vertebra of the spine.
What articulates with the vertebral column?

Why are atlas sacral and urostyle classified as a typical vertebrae?
Atlas, sacral, and urostyle vertebrae are considered typical because of their typical features for their respective regions of the spine. For example, the atlas is the first cervical vertebra that supports the skull, the sacral vertebrae fuse to form the sacrum and provide stability to the pelvis, and the urostyle is a specialized vertebra found in amphibians that supports the pelvis and hindlimbs.
What are the two most superior vertebrae?
The two most superior vertebrae are CERVICAL vertebrae 1 and 2 (C1 and C2). They are also known as the Atlas (C1) and Axis (C2). These two vertebra join together to form the atlantoaxial joint, which helps with the movement of the neck. A structure on the axis called the dens (odontoid process) fits through a foramen (hole) in the atlas to join them together.

What is at The inferior end of the sacrum is composed of several fused vertebrae?
The inferior end of the sacrum is composed of the coccyx, which is a small triangular bone formed by the fusion of 3-5 vertebrae. The coccyx serves as an attachment site for ligaments and muscles and helps support the pelvis when sitting.
