the sympathetic and parasympathetic is a division of which nervous system?
312948
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 autonomic nervous system is a division of peripheral nervous system that is not under voluntary control. It is often regarded as a self-regulating system. It controls the functions of internal body organs such as stomach, heart, lungs, urinary bladder, etc.

Autonomic nervous system. Autonomic nervous system (ANS) is a functional division of the nervous system, with its structural parts in both the central nervous system (CNS) and the peripheral nervous system (PNS). It controls the glands and smooth muscle of all the internal organs (viscera) unconsciously.

Parasympathetic nervous system: The part of the involuntary nervous system that serves to slow the heart rate, increase intestinal and glandular activity, and relax the sphincter muscles. The parasympathetic nervous system, together with the sympathetic nervous system, constitutes the autonomic nervous system.

The parasympathetic division is also called the craniosacral division because its preganglionic neurons are housed within nuclei in the brainstem and within the lateral gray matter of the S2−S4 spinal cord segments. Match the nerve with the parasympathetic effector organs it innervates.

The autonomic nervous system is divided into the sympathetic nervous system and parasympathetic nervous system. The sympathetic division emerges from the spinal cord in the thoracic and lumbar areas, terminating around L2-3.

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. Both systems of the PNS interact with the CNS and include sensory and motor neurons, but they use different circuits of nerves and ganglia.

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.

Medical Definition of Sympathetic nervous system Sympathetic nervous system: A part of the nervous system that serves to accelerate the heart rate, constrict blood vessels, and raise blood pressure. The sympathetic nervous system and the parasympathetic nervous system constitute the autonomic nervous system.

The parasympathetic nervous system is opposite in its functions generally to the sympathetic nervous system. It can informally be referred to as the part of the nervous system responsible for “rest and digest,” that is, responsible for the internal functions when you are sitting resting and relaxing.

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. It contains three anatomically distinct divisions: sympathetic, parasympathetic and enteric.

Difference between Sympathetic And Parasympathetic Nervous System. The sympathetic nervous system prepares the body for the “fight or flight” response during any potential danger. On the other hand, the parasympathetic nervous system inhibits the body from overworking and restores the body to a calm and composed state.

The Autonomic Nervous System (ANS) is divided into two functionally distinct divisions, the Sympathetic and the Parasympathetic Divisions. Each consists of nerves that control the activity of the heart, blood vessels, glands, and other organs containing smooth muscles.

Autonomic Nervous System. The autonomic nervous system is divided into three parts: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system. The autonomic nervous system controls smooth muscle of the viscera (internal organs) and glands.
1422647
The peripheral nervous system is divided into the somatic nervous system, and the autonomic nervous system. The somatic nervous system is under voluntary control, and transmits signals from the brain to end organs such as muscles.

The sympathetic division is also called the "thoracolumbar division" of the autonomic nervous system. ... Because many of the same cardiac cells are innervated by both parasympathetic and sympathetic fibers, the influence of the two divisions on the heart is synergistic.

The peripheral nervous system itself is divided into two parts: the somatic nervous system and the autonomic nervous system.
