Divisions of the Nervous System. In most animals, including humans, the nervous system consists of two parts: central and peripheral. The central nervous system (CNS) is composed of the brain, spinal cord, and cerebellum. The peripheral nervous system (PNS) consists of sensory neurons, motor neurons, and neurons that communicate either between.

The autonomic nervous system is made up of two divisions. There are many differences between these divisions. First of all there are anatomical and physiological differences. The parasympathetic division of the autonomic system origin is in the craniosacral outflow, the brain stem nuclei of cranial nerves III, VII, IX, and X; and spinal cord segments.

The peripheral nervous system is made up of the nervousnesss that bough out from the encephalon and spinal cord. These nervousnesss form the contact web associating the CNS and the organic structure parts. The peripheral nervous system is to boot subdivided into the bodily nervous system and the autonomic system. The bodily nervous system.

Explain why the terms thoracolumbar and craniosacral are appropriate for the respective divisions of the autonomic nervous system. Thoracolumber- the cell bodies of preganglionic neurons are located in the lateral grey horns of the 12 thoracic segment and first 2-3 lumbar segment of the spinal column.

This essay will describe the structure of the nervous system while explaining the role of each major section and how they interact to create and also hinder particular actions. Then.
