The human vertebral column has a more pronounced S-shape with distinct cervical, thoracic, lumbar, sacral, and coccygeal regions. Cats have a more uniform curvature with less pronounced regions, giving their vertebral column a more rigid appearance. Additionally, human vertebrae are larger and more robust compared to a cat's, supporting the bipedal nature of humans.
The function of a fetal pig's vertebral column is to reinforce the vertebrate animal. It also keeps the fragile spinal cord protected.
The primary purpose of a vertebral column is to protect the group of nerves thus enclosed. Consider the fish, or most animals which have a horizontal column. This column also acts as an anchorage for muscles and tendons, thus facilitating movement of the organism. Only in a few animals, is the vertebral column approximately vertical, and in this attitude, it enhances the apparent height of the animal, thus offering the animal a superior height for vision.

cervical, thoracic, lumbar, and sacral curvature.
Some afflictions of the vertebral column are scoliosis, lordosis, and kyphosis. These all deal with a curvatures in different regions of the vertebral column.
Kyphosis is an excessive outward curvature of the thoracic spine, causing a rounded or hunched posture. Scoliosis, on the other hand, is a lateral deviation or sideways displacement of the vertebral column, resulting in an S or C-shaped curve.
Lordosis an anteriorly convex curvature of the vertebral column; the normal lordoses of the cervical and lumbar regions are secondary curvatures of the vertebral column, acquired postnatally
thoracic vertebrae
The vertebral column (commonly called "Backbone") is located directly on the opposite side of the thoracic (chest) cavity relative too the sternum. In short... vertebral column is the backbone, in the back... the sternum is the front of the rib cage, in the front.

Primary curvature refers to the curvature of the spine in the sagittal plane, specifically in the thoracic and sacral regions. The primary curvatures are kyphotic, meaning they curve outward, with the thoracic spine curving posteriorly and the sacral spine curving anteriorly. These primary curvatures are present at birth and help to maintain balance and support the weight of the body.
