To compare: The anatomic differences in the lower motor neurons and associated ganglia of the parasympathetic and sympathetic divisions. Concept introduction: The autonomic nervous system is a functional division of the peripheral nervous system. It involves two autonomic neurons in the efferent pathway, namely preganglionic neurons and postganglionic neurons. The cell body of the preganglionic neurons is in the central nervous system (CNS), whereas the postganglionic neurons lie entirely outside the CNS. The autonomic nervous system is (structurally and functionally) divided into two parts, namely the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).

(This is a 2-part work, Part 1 is done, only Part 2 is to be worked on at the bottom)Part 1 (Done): Describe the levels of structural hierarchy for the human body, starting with the organismal level and ending with the chemical level. In addition, you should make sure you link each level to the previous level, emphasizing the structural relationships. The human body is organized into a structural hierarchy that progresses from the macroscopic organismal level down to the microscopic chemical level. Each level builds upon the previous one, creating increasingly complex structures. Below is the hierarchy, from largest to smallest, with explanations linking each level to its predecessor: 1. Organismal Level The entire living human body.Relationship: All lower levels work together to sustain life at this highest level. 2. Organ System Level Groups of organs working together to perform major functions.Examples: circulatory, nervous, digestive systems.Relationship: The organismal…
