How Homeostasis Is Controlled By The Autonomic Nervous System.

As the Autonomic Nervous System is such an important part of the nervous system, studying it and knowing how it works, and how it is controlled, is also very important; in this essay I am going to talk about the three different branches of the Autonomic Nervous System and their functions and differences, and then explain how they are regulated in the brain.The Autonomic Nervous System(ANS) is a division derived from the PNS and plays a role in conducting nerve impulses and in transmitting information to the CNS. It focuses more on the involuntary actions one 's body may experience(breathing is an example of this). Like most aspects of one 's body, these systems are not exempt from damage or disease.The Autonomic Nervous System consists of both sensory and motor neurons the travel between the CNS. The internal organs that are associated with the nervous system are the heart, the lungs, the viscera and the glands. This system is responsible for the monitoring conditions of the internal environment.


The autonomic nervous system is automatic, and in control of voluntary bodily functions. It is separated into two parts; the sympathetic and parasympathetic nervous system. It regulates the function of the glands, the adrenal medulla, smooth muscle tissue, organs and the heart. 1.2 Explain the functions of each part of the nervous system.Autonomic nervous system, in vertebrates, the part of the nervous system that controls and regulates the internal organs without any conscious recognition or effort by the organism.
