The 23 pages that link to Notochord, each with the reason it gives.

• VertebrateRelated: In vertebrate development, it is partly or largely replaced by the vertebral column.

• NeurulationRelated: It induces overlying ectoderm to adopt neural character.

• LampreyRelated: A persistent notochord provides much of the axial support in lampreys.

• HagfishRelated: Hagfish retain a persistent notochord that supports the body without a bony vertebral column.

• Jawless fishRelated: It provides axial support in jawless fish, alongside or instead of vertebral elements.

• InvertebrateRelated: A notochord is not a vertebral column, clarifying why some chordates are invertebrates.

• HaikouichthysRelated: A notochord is among the internal structures attributed to Haikouichthys.

• AgnathaRelated: A persistent notochord provides axial support in many jawless vertebrates.

• Early vertebrateRelated: It supported early chordate bodies before vertebral structures became prominent.

• TunicateRelated: The larval notochord is a key sign of tunicate chordate ancestry.

• Pharyngeal slitRelated: It is another defining chordate feature, distinct from the pharyngeal slits.

• LepospondyliRelated: Persistent notochords shaped the vertebral anatomy used to identify many lepospondyls.

• AscidiaceaRelated: It occurs in the ascidian larval tail and is lost during the usual metamorphosis.

• CyclostomiRelated: Cyclostomes retain a notochord as adults rather than replacing it completely with vertebrae.

• VetulicoliaRelated: A notochord has been proposed in some interpretations of vetulicolian fossils, but is not securely established.
