Document Summary

Sacral vertebrae: vertebrae in the hips; the pelvic bones are fused to the sacral vertebrae to support powerful leg muscles; the sv are also fused with one another and form a single solid bone structure. Caudal vertebrae: vertebrae in the tail underneath the cv are bones called chevrons. Chevrons: protect a large blood and nerve channel and provide support for tail muscles.
