Want this question answered?
a backbone eg. horse and invertebrates have no backbone
the backbone actually consists of spinal cord.spinal cord carries the nerves to brain the message for movement of lower part or any part of the body is sent by brain through spinal cord.so ,if backbone breaks the person will become paralysed.

Most animals are more highly protected on their dorsal side. The dorsal side is the backbone side if the animal has a backbone. Most of the harder bones and protection is on that side. The ventral, or belly side, is almost always more vulnerable and softer.
The backbone protects your spinal nerve and helps keep all the upper body structures and organs in place. And obviously helps your body to stay straight and your head to be where it is.
