Animals that have a spine are called vertebrates, and animals that don't have one are called invertebrates. Humans have a spine, so we are vertebrates. Many vertebrates, including mammals, have intervertebral discs separating the vertebrae. Regions. The vertebral column is divided by doctors into 5 sections called regions. These 5 regions from top to bottom are: Cervical - Shown in red, this region supports the head. It is made up of 7 vertebrae. The first two, called the atlas and axis, connect the spine to the skull. Thoracic - Shown in blue, this region supports the ribs.
The human vertebral column is the vertebral column (backbone or spine) of the human skeleton, consisting of 24 articulating vertebrae and 9 fused vertebrae in the sacrum and the coccyx.The vertebrae in the column are separated from each other by intervertebral discs.hese regions are called the cervical spine, thoracic spine, lumbar spine, sacrum and coccyx. There are a total of 33 vertebrae in the vertebral column. The articulating vertebrae are named according to their region of the spine.
