The postcranial subdivision of skeleton structural components forming the long axis of the vertebrate body; in Danio, consisting of the notochord, vertebrae, ribs, supraneurals, intermuscular bones, and unpaired median fins; in human consists of the bones of the vertebral column, the thoracic cage and the pelvis[ZFA+FMA].
Comment:
previous some AOs had used the term 'axial skeleton' to include the skull. This is being resolved (see tracker items above). Status: MA - fixed.; [homology-note] "The axial musculoskeletal system represents the plesiomorphic locomotor engine of the vertebrate body, playing a central role in locomotion. In craniates, the evolution of the postcranial skeleton is characterized by two major transformations. First, the axial skeleton became increasingly functionally and morphologically regionalized. Second, the axial-based locomotion plesiomorphic for craniates became progressively appendage-based with the evolution of extremities in tetrapods.[well established][VHOG]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0000317", ontology="VHOG", source="DOI:10.1186/1742-9994-8-4 Schilling N, Evolution of the axial system in craniates: morphology and function of the perivertebral musculature.
