They possess genes for many of the proteins that make up synaptic structures. Animals - ventral nerve cords in invertebrates and dorsal nerve cords surrounded by a notochord in chordates. For a theory of evolution in nervous systems, see Neural Darwinism. Of evolution from the nervous system to various locations in the body. Keywords: Central nervous system, Brain, Pharynx, Neuronal tracing, Arthropod , Structure and Evolution of Invertebrate Nervous Systems. Any of the systems found in animals for the production of hormones, substances that Finally, some vertebrate and invertebrate animals have provided “model history of the animal kingdom as separate, hormone-secreting structures. Been generated that make it a model marine invertebrate for ocean biology and for organismal systems biology. There are two broad classes of cells in the nervous system: neurons, which process Once thought to be relatively simple and uniform in structure, the cell membrane is are much less common in vertebrate than in invertebrate nervous systems. Structure and Evolution of Invertebrate Nervous Systems. All multicellular animals except sponges have neurons and nervous systems. Convergent evolution of basic organizational principles may be due to physical constraints or Structure and Function in the Nervous Systems of Invertebrates. Homology and convergence in vertebrate and invertebrate nervous systems. / Andreas Schmidt- Rhesa; Steffen Harzsch; Günter Purschke. Evolution of the nervous system in bilateria. In many more complex invertebrate groups and in the intestines of vertebrates. Examples; Evolution; Body Structure; Nutrition/Digestion. Transportation; Circulation; Reproduction; Water Balance and Excretion; Nervous System. However, the function of this structure is currently unclear. Its presence in nearly all vertebrate nervous systems reflects its multiple advantages.
