A. autonomic nervous system
Dysfunction of the autonomic nervous system (ANS) is known as dysautonomia. The autonomic nervous system regulates unconscious body functions.
Hypothalamus is supposed to be the highest center in of autonomic nervous system in your body. Autonomic nervous system is supposed to be responsible for all the automatic functions going on in your body.
Autonomic Nervous System
The autonomic nervous system controls involuntary activities of the body, such as heart rate, digestion, breathing, and blood pressure.
You are probably referring to "involuntary body functions" - and the answer would be the autonomic nervous system. This system could be further divided into the sympathetic nervous system and the parasympathetic nervous system.
The two integral parts of the autonomic nervous system are the sympathetic nervous system responsible for, "rest and digest" and the parasympathetic nervous system that is responsible for, "fight or flight".
each and every part of body is controlled by the nervous system.
The somatic and autonomic nervous systems make up the peripheral nervous system. The main function of this system is to connect the central nervous system to the limbs and organs in the body.
The major part of the nervous system that includes the autonomic nervous system is the peripheral nervous system (PNS). The PNS is divided into the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary functions such as heart rate, digestion, and respiratory rate. The autonomic nervous system is further subdivided into the sympathetic and parasympathetic nervous systems, which manage the body's responses to stress and relaxation, respectively.
It might be your mind.
The autonomic nervous system controls the body's unconscious activities, such as heart rate, digestion, and breathing. It is responsible for regulating these functions to maintain homeostasis in the body without conscious effort.
