Transverse process- Transverse process is a small bony projection off the right and left side of each vertebrae. The two transverse processes of each vertebrae function as the site of attachment for muscles and ligaments of the spine as well as the point of articulation of the ribs

what is Atlas
the topmost vertebra of the backbone, articulating with the occipital bone of the skull
What is the cervical vertebrae
The cervical spine is the most superior portion of the vertebral column, lying between the cranium and the thoracic vertebrae. It consists of seven distinct vertebrae, two of which are given unique names: The first cervical vertebrae (C1) is known as the atlas. The second cervical vertebrae (C2) is known as the axis.
What is the thoracic vertebrae
The twelve thoracic vertebrae are strong bones that are located in the middle of the vertebral column, sandwhiched between the cervical ones above and the lumbar vertebrae below. Like typical vertebrae, they are separated by intervertebral discs.
What are lumbar vertebrae
The lumbar spine is the third region of the vertebral column, located in the lower back between the thoracic and sacral vertebral segments. It is made up of five distinct vertebrae, which are the largest of the vertebral column. This supports the lumbar spine in its main function as a weight bearing structure.
What are Sacral vertebrae
Sacrum - the main function of the sacrum is to connect the spine to the hip bones (iliac). There are five sacral vertebrae, which are fused together. Together with the iliac bones, they form a ring called the pelvic girdle.
What are between the vertebrae
intervertebral discs- The intervertebral discs (or discs) are fibrocartilages lying between adjacent surfaces of the vertebrae. They form a fibrocartilaginous joint between the vertebral bodies, linking them together.
Role of intervertebral discs
The intervertebral discs provide cushioning between vertebrae and absorb pressure put on the spine.
What are Spinous processes
This process points dorsally and caudally from the junction of the laminae. The spinous process serves to attach muscles and ligaments.
Where are Spinous processes located
opposite transverse processes
