What are the two largest differences between the nervous systems of vertebrates and arthropods?
Homework Answers
In Vertebrates, the nervous system consists of Brain and Spinalcord. It is divided into CNS that is, Central Nervous System and PNS that is, Peripheral Nervous System.
But in Arthropods, the nervous system consists of a Dorsal Brain and a ventral, Ganglionated longitudinal nerve cord.
In Vertebrates, one Neuron controls many muscle cells. For example, one signal is enough to perform a muscle movement. Because one neuron supplies impulses to a number of muscle cells, together forming a functional motor unit.
But in Arthropods, one muscle cell is controlled by many neurons. So the contraction of the Arthropod muscle is achieved by getting impulses from several different types of neurons to the one muscle cell.

Identify the two major divisions of the peripheral nervous system. Differentiate between the somatic (motor) nervous system and the sympathetic and parasympathetic branches of the autonomic nervous system in terms of (1) overall anatomic organization (numbers, types of nerves); (2) neurotransmitters made and released by the nerves; and (3) the targets (effectors) of the neurotransmitters’ actions, whether those structures are innervated by one or both branches of the autonomic nervous system, and the effects of activating those structures. ...

All vertebrates are chordates, but not all chordates are vertebrates. Compare the three subgroups hemichordata, cephalochordata, urochordata and explain the differences i) between the groups and ii) between those phyla and the vertebrates, iii) and describe the relationship of the hemichordates to other deuterostomes. Finally, iv) What physical feature found in all three groups is an advantage that led to the “pre-adaptedness” found in chordates?
