Autonomic Nervous System: What It Is, Function & Disorders
Your autonomic nervous system is a network of nerves throughout your body that control unconscious processes. These are things that happen without you thinking about them, such as breathing and your heart beating. Your autonomic nervous system is always active, even when you’re asleep, and it’s key to your continued survival.
Autonomic nervous system - Wikipedia

自主神经系统调控血压、心率、体温、体重、消化、新陈代谢、体液和电解质平衡、出汗、排尿、排便、性反应和其他生理过程。 很多器官可同时接受交感和副交感神经的冲动传入，但常以交感支配为主或以副交感支配为主，有时，交感和副交感的作用是相互拮抗的（如交感神经系统使心率增快，而副交感神经系统使心率减慢）。 交感神经系统促进分解代谢及激起人体的逃避反射（战斗或逃跑反应）。 副交感神经系统则促进合成代谢，它能将各种物质转化并储存起来 (见表自主神 …
Overview of the Autonomic Nervous System - MSD Manuals
The autonomic nervous system regulates physiologic processes. Regulation occurs without conscious control, ie, autonomously. The 2 major divisions are the. Disorders of the autonomic nervous system cause autonomic insufficiency or failure and can affect any system of the body.

The autonomic nervous system controls cardiac and smooth muscle, as well as glandular tissue. The somatic nervous system is associated with voluntary responses (though many can happen without conscious awareness, like breathing), and the autonomic nervous system is associated with involuntary responses, such as those related to homeostasis.
