In chordates the nervous system is dorsal and highly cephalized while in most invertebrates the nervous system is ganglial and ventral.

Description : In chordates the nervous system is dorsal and highly cephalized while in most invertebrates the nervous system is ganglial and ventral.

Last Answer : What is the group of the phylum Chordata that first colonized the terrestrial environment?

The tubular and dorsal nervous system of chordates is related to the cephalization in these animals and to bilateral symmetry. The presence of neural integrating centers with concentration of neurons in the brains and the spinal cord (central nervous system, CNS) allowed the increase of the interaction complexity between these animals and the environment. Receptor (afferent conduction) and efferent (motor, regulatory and behavioral reactions) functions come out more sophisticated in chordates due to the presence of more well-developed neural networks. These features have been preserved by evolution as they provide adaptive advantage to their owners.
