Vertebrates include birds, fish, amphibians, reptiles, and mammals. The parts of the vertebrate skeleton are:

Braincase: A braincase or cranium protects the brain.

Vertebrae: A series of short, stiff vertebrae are separated by joints. This internal backbone protects the spinal cord. The joints between the vertebrae let the backbone bend.

Bones: support and protect the body's soft tissues and provides points for muscle attachment.

Gill arches: Gill arches in the pharynx of fish and some amphibians support the gills. In the majority of vertebrates some of the arches have evolved into other organs, such as jaws.
