Abstract

The majority of chordates belong to the subphylum Vertebrata, a group which, as its name suggests, is characterized by the possession of a metameric series of small skeletal structures, the vertebrae. These are associated with the notochord during embryonic development but in most cases replace it in adults. Like the notochord the vertebral column functions as an axial supporting rod, but it has the additional function of protecting the nerve cord. In vertebrates the anterior end of the nerve cord is greatly expanded to form a brain, and a skeletal structure, the neurocranium (or, more simply, the cranium) has developed to protect it.
