The function of a fetal pig's vertebral column is to reinforce the vertebrate animal. It also keeps the fragile spinal cord protected.
In general, the human vertebral column has a soft S shape. The cat's vertebral column, on the other hand, is a soft C shape. That is to say, a cat's vertebral column curves once whereas the human's curves twice, in opposite directions.
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.

The vertebral column is inferior to the skull.
Erector spinae are the muscles that move the vertebral column.It is the largest muscle mass of the back, forming a prominent bulge on either side of the vertebral column.It is the chief extensor of the vertebral column. It is also important in controlling flexion, lateral flexion and rotation of the vertebral column and in maintaining the lumbar curve, because the main mass of the muslce is in the lumbar region.Consists of: iliocostalis, longissimus and spinalis.Erector spinae are the muscles that move the vertebral column.

You tend to think about the sacrum. But it is not the case. You have the tail bone or the coccyx. It is the most inferior bone in the vertebral column.
the vertebral column is located below your skull on your back.
Some afflictions of the vertebral column are scoliosis, lordosis, and kyphosis. These all deal with a curvatures in different regions of the vertebral column.
yes, all vertebrates and chordates have a vertebral column
Lumbar vertebral column
The vertebral column is located posterior to the trachea, which means it is behind the trachea. Additionally, the vertebral column is superior to the trachea, indicating it is situated above the trachea in the body.
The lumbar vertebrae are the largest segments of the movable part of the vertebral column
