Oct 31, 2023 · A dorsal nerve cord which develops from a plate of ectoderm that rolls into a tube located dorsal to the notochord. Other animal phyla have solid nerve cords ventrally located. A chordate nerve cord splits into the central nervous system: the brain and spinal cord.

Chordates are a diverse group of animals that comprise the phylum Chordata. The phylum is divided into three subphyla based on general physical characteristics: Urochordata, Cephalochordata, and Vertebrata. Urochordates have a notochord (a hollow dorsal nerve cord) while in the larvae stage but lose it later in their adult stage.
