Your autonomic nervous system is a part of your overall nervous system that controls the automatic functions of your body that you need to survive. These are processes you don’t think about and that your brain manages while you’re awake or asleep.

Autonomic functions include control of respiration, cardiac regulation (the cardiac control center), vasomotor activity (the vasomotor center), and certain reflex actions such as coughing, sneezing, swallowing and vomiting. Those are then subdivided into other areas and are also linked to autonomic subsystems and the peripheral nervous system.

2021年1月15日 · The autonomic nervous system (ANS) maintains blood pressure, regulates the rate of breathing, influences digestion, urination, and modulates sexual arousal. The sympathetic portion of the ANS controls reactions like the stress response and the fight-or-flight reaction.

2023年5月9日 · The autonomic nervous system is a network of nerves that regulates unconscious body processes. The autonomic system is the part of the peripheral nervous system responsible for regulating involuntary body functions, such as heartbeat, blood flow, breathing, and digestion.

2023年7月24日 · 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.

2023年11月3日 · The 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.

2023年9月25日 · Your autonomic nervous system is the aspect of the nervous system that controls all of your vital functions, like breathing, digestion, and heart rate—many of which you aren't consciously aware of. In short, it keeps you alive.

2023年6月26日 · What is the autonomic nervous system? What affects how it works? The autonomic nervous system is a complex network of cells that controls the body’s internal state. It regulates and...

2025年1月11日 · The autonomic nervous system comprises two antagonistic sets of nerves, the sympathetic and parasympathetic nervous systems. The sympathetic nervous system connects the internal organs to the brain by spinal nerves.

2025年1月21日 · Learn how these two systems differ in their functions as they help the body maintain homeostasis. The sympathetic nervous system normally functions to produce localized adjustments (such as sweating as a response to an increase in temperature) and reflex adjustments of the cardiovascular system.
