There are essentially 3 curves in the human spine:
1. Cervical lordotic curve
2. Thoracic kyphotic curve
3. Lumbar lordotic curve
In summary the human spine has 2 lordotic curves and 1 kyphotic curve.
If you are looking at a person sideways with their face facing towards your left, the lordotic curve is concave and the kyphotic curve is convex.
The spinal curvatures in the thoracic and sacral regions are referred to as primary curvatures.
Starting superiorly (towards the head) it is concave in the cervical vertebre, convex in the thoracic, concave in the lumbar and convex in the saccral and coccygeal vertebres.

Thoracic and sacral curves.
The vertebral column and skull is another description for the spinal column. See the related link for more information. The entire vertebral column consists of the skull, the 33 vertebrae and the ribcage.
The bones of the skeleton are in some way connected to the vertebral column.
dorsal means being behind in position of so yes it is dorsal to the sternum
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.
Compression.
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 vertebral column is inferior to the skull.
the sternum is anterior to the vertebral column
the sternum is anterior to the vertebral column
the alimentary canal is ventral to the vertebral column.
the alimentary canal is ventral to the vertebral column.
the vertebral column is located below your skull on your back.
vertebral column is inferior to the tranchea
Some afflictions of the vertebral column are scoliosis, lordosis, and kyphosis. These all deal with a curvatures in different regions of the vertebral column.
Lumbar vertebral column
yes, all vertebrates and chordates have a vertebral column
