what are the 3 divisions of the autonomic nervous system?

The autonomic nervous system has three branches: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system. Some textbooks do not include the enteric nervous system as part of this system.

Description. The autonomic nervous system (also known as the visceral nervous system and vegetative nervous system) combines with the somatic nervous system to form the efferent (i.e., outgoing) division of the peripheral nervous system.

The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.

Four divisions of the Peripheral Nervous System (PNS) Visceral motor system deals with the involuntary contraction of smooth and cardiac muscle. This includes the sympathetic division (fight or flight) and parasympathetic division (rest and digest) which include the autonomic nervous system.

The parasympathetic nervous system is one of the two main divisions of the autonomic nervous system (ANS). Its general function is to control homeostasis and the body's rest-and-digest response.

Divisions of the Nervous System Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.

Introduction. The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.

The autonomic nervous system has three branches: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

Divisions of the Peripheral Nervous System. The PNS is divided into two major systems, called the autonomic nervous system and the somatic (or sensory-somatic) nervous system.

The peripheral nervous system is itself classified into two systems: the somatic nervous system and the autonomic nervous system. Each system contains afferent and efferent components.

In the peripheral nervous system, bundles of nerve ﬁbers or axons conduct information to and from the central nervous system. The autonomic nervous system is the part of the nervous system concerned with the innervation of involuntary structures, such as the heart, smooth muscle, and glands within the body.

The autonomic nervous system (ANS) is classically divided into two subsystems: the parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS). The enteric nervous system is sometimes considered part of the autonomic nervous system, and sometimes considered an independent system.

The parasympathetic nervous system (PSNS) is one of the two divisions, the other being the sympathetic, that together are called the autonomic nervous system, which is a division of another system called the peripheral nervous system (PNS)).

The two divisions of the autonomic nervous system are the sympathetic division and the parasympathetic division. The sympathetic system is associated with the fight-or-flight response, and parasympathetic activity is referred to by the epithet of rest and digest. Homeostasis is the balance between the two systems.

Peripheral Nervous System. The peripheral nervous system is divided into two major parts: the somatic nervous system and the autonomic nervous system.

The structures of the nervous system are described in terms of 2 principal divisions-the central nervous system (CNS) and the peripheral nervous system (PNS).
