Anatomy and Physiology 2013-06-19T00:00:00Z For any given target, the difference in which division of the autonomic nervous system is exerting control is just in what chemical binds to its receptors. Anatomy and Physiology 2013-06-19T00:00:00Z At most of the other targets of the autonomic system, the effector response is based on which neurotransmitter is released and what receptor is present. Anatomy and Physiology 2013-06-19T00:00:00Z It is really an extension of the autonomic nervous system, which regulates homeostasis in the body. Anatomy and Physiology 2013-06-19T00:00:00Z In this example, the autonomic system is controlling how much light hits the retina. Anatomy and Physiology 2013-06-19T00:00:00Z For each organ system, there may be more of a sympathetic or parasympathetic tendency to the resting state, which is known as the autonomic tone of the system.

Anatomy and Physiology 2013-06-19T00:00:00Z Figure 15.11 Fiber Tracts of the Central Autonomic System The hypothalamus is the source of most of the central control of autonomic function. Anatomy and Physiology 2013-06-19T00:00:00Z The primary responsibilities of the autonomic nervous system are to regulate homeostatic mechanisms in the body, which is also part of what the endocrine system does. Anatomy and Physiology 2013-06-19T00:00:00Z Secondly, control of the body can be somatic or autonomic—divisions that are largely defined by the structures that are involved in the response. Anatomy and Physiology 2013-06-19T00:00:00Z The key to understanding the autonomic system is to explore the response pathways—the output of the nervous system. Anatomy and Physiology 2013-06-19T00:00:00Z The synapses in the autonomic system are not always the typical type of connection first described in the neuromuscular junction. Anatomy and Physiology 2013-06-19T00:00:00Z The afferent branch of the somatic and visceral reflexes is very similar, as many somatic and special senses activate autonomic responses. Anatomy and Physiology 2013-06-19T00:00:00Z The two divisions of the autonomic system each play a role in effecting change, usually in competing directions. Anatomy and Physiology 2013-06-19T00:00:00Z Voluntary responses are governed by the somatic nervous system and involuntary responses are governed by the autonomic nervous system, which are discussed in the next section. Anatomy and Physiology 2013-06-19T00:00:00Z Which of the following represents a sensory input that is not part of both the somatic and autonomic systems?

Anatomy and Physiology 2013-06-19T00:00:00Z The role of the autonomic system is to regulate the organ systems of the body, which usually means to control homeostasis. Anatomy and Physiology 2013-06-19T00:00:00Z Normally, the vagus nerve is considered autonomic in nature. Anatomy and Physiology 2013-06-19T00:00:00Z A typical human cannot survive without breathing for more than 3 minutes, and even if you wanted to hold your breath longer, your autonomic nervous system would take control. Anatomy and Physiology 2013-06-19T00:00:00Z Figure 19.35 Summary of Major Factors Influencing Cardiac Output The primary factors influencing HR include autonomic innervation plus endocrine control. Anatomy and Physiology 2013-06-19T00:00:00Z Reflexes such as coughing, and the ability of the lungs to regulate oxygen and carbon dioxide levels, also result from this autonomic nervous system control.

Anatomy and Physiology 2013-06-19T00:00:00Z Also, cardiac muscle tissue is only modulated by autonomic inputs, so the conflicting information from both sympathetic and parasympathetic postganglionic fibers will cause arrhythmias. Anatomy and Physiology 2013-06-19T00:00:00Z The autonomic system integrates sensory information and higher cognitive processes to generate output, which balances homeostatic mechanisms. Anatomy and Physiology 2013-06-19T00:00:00Z Autonomic ganglia are in the sympathetic chain, the associated paravertebral or prevertebral ganglia, or in terminal ganglia near or within the organs controlled by the autonomic nervous system.

Anatomy and Physiology 2013-06-19T00:00:00Z The majority of hypothalamic output travels through the medial forebrain bundle and the dorsal longitudinal fasciculus to influence brain stem and spinal components of the autonomic nervous system. Anatomy and Physiology 2013-06-19T00:00:00Z These higher centers have descending control of the autonomic system through brain stem centers, primarily in the medulla, such as the cardiovascular center. Anatomy and Physiology 2013-06-19T00:00:00Z The autonomic system is affected by a number of exogenous agents, including some that are therapeutic and some that are illicit. Anatomy and Physiology 2013-06-19T00:00:00Z The projections of the sympathetic division of the autonomic nervous system diverge widely, resulting in a broad influence of the system throughout the body.
