This chapter weaves an in-depth discussion of the physical function of releasing our bodies into the support of gravity with an analysis of how that experience can serve as an important stability in our daily lives. It begins by reviewing the crucial distinction between collapsing and yielding in order to demonstrate how the same force that draws us to the ground can also sponsor our action in the world, helping us find a sense of resistance and agency. In addition, gravity can provide a useful counterbalance to the ubiquitous presence of two-dimensional screens in our lives. By allowing us to experience weight, gravity is key to our sense of grounding, linking inhalation with exhalation, sky to earth, as well as the sympathetic and parasympathetic aspects of our autonomic nervous system.

The autonomic nervous system is involved in many important unconscious body functions. It is critical for maintaining the internal environment in response to changes in the external environment. The autonomic nervous system consists of peripheral components (sympathetic and parasympathetic nerves and ganglia) and central components (ventrolateral medulla, nucleus ambiguus, nucleus of the solitary tract, periaqueductal gray, anterior cingulate gyrus, insular cortex, amygdala, and hypothalamus). This chapter briefly reviews the anatomy and functional components of the autonomic nervous system and several anatomical clinical correlations.

This chapter provides an overview of the autonomic nervous system and respective instructions for drawing its various components. These include the, parasympathetic nervous system, sympathetic nervous system, lower urinary system, baroreceptor reflex, respiration, and digestive tract. The chapter discusses the various functions of elements of these systems, and it presents conditions and illnesses specifically related to disorders in elements of the autonomic nervous system, such as cardiac rhythm abnormalities (arrhythmias), respiratory failure, gut dysmotility, bladder dysmotility, and skin manifestations, such as hair fiber loss and sweating.

Chapter 6 discusses how to draw the peripheral nervous system, specifically the autonomic nervous system, including autonomic fiber arrangements, the parasympathetic nervous system, the sympathetic nervous system, the urinary system, and the cardiac reflex.

The autonomic nervous system innervates all organs, producing predominantly involuntary and automatic actions that are mediated by two principal efferent pathways, the sympathetic and parasympathetic, which are neurochemically and anatomically distinct. Numerous synaptic relays and neurotransmitters allow the autonomic control of organ function at local and central levels to be integrated with the requirements of the whole body....

The autonomic nervous system innervates all organs, producing predominantly involuntary and automatic actions that are mediated by two principal efferent pathways, the sympathetic and parasympathetic, which are neurochemically and anatomically distinct. Numerous synaptic relays and neurotransmitters allow the autonomic control of organ function at local and central levels to be integrated with the requirements of the whole body. The peripheral and central components of the autonomic nervous system are frequently affected by diseases, conditions, or toxins. Autonomic disorders are described as (1) primary—without defined cause, including multiple system atrophy and acute/subacute dysautonomias; or (2) secondary—with specific defects or as a consequence of other conditions, including diabetes mellitus, Riley–Day syndrome, amyloid neuropathy, dopamine β‎-hydroxylase deficiency, spinal cord injury, and many drugs.

This chapter on the autonomic nervous system (ANS) covers the neural anatomy of the sympathetic (SNS), parasympathetic (PNS), and enteric (ENS) nervous systems. The activation and inactivation as well as the interaction between the SNS and PNS are examined with specific attention to the receptor and secondary messenger systems associated with the SNS and PNS. It also describes in detail the upregulation and downregulation of the SNS and PNS. It examines both adrenergic (synthesis, storage, and release of norepinephrine) and cholinergic pharmacology (acetylcholine synthesis, storage and release, and inactivation) and also discusses the genetic contributors to autonomic function and dysfunction.

A basic understanding of the functional and physiological structure of the autonomic nervous system (ANS) is essential in interpreting test results. This chapter summarizes the functional anatomy of the ANS. The ANS has been divided into the central autonomic system (CAN), also called preganglionic system, and the peripheral (or postganglionic system), which includes the parasympathetic system, sympathetic system, and enteric system. The anatomy and functions of the ANS and its various divisions are explained. Also described is the anatomy and functions of the baroreceptor reflex (BR), which is important in controlling the heart rate and blood pressure.

The autonomic nervous system is a critical effector of an internal regulation system that controls functions necessary for survival. Autonomic outputs regulate the activity of the heart; the smooth muscle of the blood vessels, pupil, and visceral organs; and the exocrine glands. The autonomic nervous system includes 3 subdivisions: the sympathetic, parasympathetic, and enteric nervous systems. Autonomic disorders may be prominent manifestations of several neurologic diseases and, in some cases, may be valuable in localizing lesions in the nervous system.
