SpletThe notochord signals the neural plate cells to fold over to form a tube called the neural tube, as illustrated below. During later development, the notochord will disappear (it goes on to help form the spongy discs between the vertebrae), and the neural tube will give rise to the brain and the spinal cord. SpletCharacteristics of Chordata. Animals in the phylum Chordata share five key chacteristics that appear at some stage during their development: a notochord, a dorsal hollow (tubular) nerve cord, pharyngeal gill arches or slits, a post-anal tail, and an endostyle/thyroid gland (Figure 2). In some groups, some of these key chacteristics are present only during …
