backbone
Definition
A backbone is a structure that provides support and flexibility. It is often made up of a series of bones or other rigid structures that are connected together.
In the human body, the backbone is the spinal column. It is made up of 33 individual bones, called vertebrae, that are stacked on top of each other. The vertebrae are connected by ligaments and joints, which allow the backbone to move.
The backbone provides support for the head, neck, and torso. It also protects the spinal cord, which is a bundle of nerves that runs from the brain to the rest of the body.
The backbone is an important part of the human body. It allows us to move, and it protects our spinal cord.
