The spinal column has numerous important functions and must be protected carefully against injuries, compressions, and strains. Of the most well-studied examples is the human vertebral column. These structures are separated by a series of membranes known as the Meninges. The vertebrae are divided into three groups. In turtles some vertebrae may be fused to the shell (carapace); in birds all but the cervical vertebrae are usually fused into a rigid structure, which lends support in flight.
