The autonomic system is a crucial part of the human body that controls involuntary functions such as heart rate, digestion, and breathing. It is responsible for maintaining the body’s internal environment and ensuring that it functions correctly. In this article, we will explore the definition and meaning of the autonomic system, its origin, and its associations.
Definitions
The autonomic system is a part of the nervous system that controls involuntary actions of the body. It is responsible for regulating the functions of internal organs, including the heart, lungs, and digestive system. The autonomic system is divided into two branches, the sympathetic and parasympathetic nervous systems, which work together to maintain homeostasis in the body.
Origin
The term “autonomic” is derived from the Greek words “auto,” meaning self, and “nomos,” meaning law. The autonomic system was first described by the French physiologist Claude Bernard in the mid-19th century. He observed that certain bodily functions, such as digestion, were regulated by the nervous system without conscious control.
