English-Hanzi/Spine

The spine is a column of vertebrae in the back part of the torso (upper body). It is also called the backbone or vertebral column. There is a canal that runs through the length of the spine. Inside this canal is the spinal cord. 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.
