Question

Quizplus · Accepted Answer

The nervous system of vertebrates has a hierarchical structure, meaning that it is organized into different levels of processing and control. Invertebrates may have a central nervous system, but it is not organized in the same hierarchical manner as the vertebrate nervous system. Invertebrates may also have ganglia, which are clusters of nerve cells that function similar to a brain, but they do not have a comparable spinal column. The size of the cerebral cortex is also not a reliable way to differentiate between the nervous systems of vertebrates and invertebrates.
