WebThe notochord supports the whole tail of the larva but just part of its body. This arrangement gives the subphylum its name, Urochordata (Greek root words uro meaning tail and chord meaning string ). The tunicate larva is a bilaterally symmetrical, free-swimming animal that looks like a tadpole or a lancelet (Fig. 3.100). Research into the notochord has played a key role in understanding the development of the central nervous system. By transplanting and expressing a second notochord near the dorsal neural tube, 180 degrees opposite of the normal notochord location, one can induce the formation of motor neurons in the dorsal tube. Motor neuron formation generally occurs in the ventral neural tube, while the dorsal tube generally forms sensory cells.
