Science Biology PRIN.OF HUMAN ANATOMY (LL)

The relation between the adrenal medulla and the autonomic nervous system (ANS) in the body. Introduction: The ANS is classified as a portion of the PNS (peripheral nervous system) of the body that operates through electrical signals that move along the long chain of ganglia. It is controlled by the hypothalamus in the brain. The adrenal medulla is a part of the endocrine system, which operates in the body through hormones. Explanation: The ANS has two branched namely, the sympathetic and parasympathetic nervous systems. These are under the involuntary control of an external stimulus. The ANS is responsible for the generation of the stress response during the condition of stress. The adrenal medulla is the soft portion of the adrenal gland, which secretes hormones in response to the stress. The stressor affects the hypothalamus in the brain. The hypothalamus further sends the nerve signals to the sympathetic division of the. This division of the ANS sends the signals to the adrenal medulla. The adrenal medulla, in response to the signals, secretes the epinephrine and norepinephrine. These two hormones secreted by the adrenal medulla are responsible for the initiation of the flight-and-fight syndrome. Conclusion: Thus, the hypothalamus causes the stimulation of ANS during a stress, which in turn causes the stimulation of the adrenal medulla to produce the hormones.
