All of these organisms have a braincase of cartilage or bone that surrounds the brain. All vertebrates have a hollow dorsal nerve cord, ventral body cavities, and a musculartail, although in humans this structure is reduced to the four elements of the coccyx. All vertebrates also share the "tube within a tube" pattern of hollow body cavities that contain tubular structures, such as the digestive tract. At some stage of development (often only embryonic), vertebrates also have a notochord and pharyngeal (gill) arches.
