Detailed explanation-1: -Your medulla oblongata is the bottom-most part of your brain. Its location means it’s where your brain and spinal cord connect, making it a key conduit for nerve signals to and from your body. It also helps control vital processes like your heartbeat, breathing and blood pressure.
Detailed explanation-2: -The medulla oblongata controls breathing, blood pressure, heart rhythms and swallowing. Messages from the cortex to the spinal cord and nerves that branch from the spinal cord are sent through the pons and the brainstem.
Detailed explanation-3: -The medulla oblongata is responsible for regulating several basic functions of the autonomic nervous system, including respiration, cardiac function, vasodilation, and reflexes like vomiting, coughing, sneezing, and swallowing.
Detailed explanation-4: -The medulla oblongata connects directly to the heart through two different pathways: the vagus nerve and the accelerator nerve. The vagus nerve is part of the parasympathetic nervous system and it releases acetylcholine into the heart making it decrease the heart rate.
Detailed explanation-5: -The respiratory center is located in the medulla oblongata and is involved in the minute-to-minute control of breathing. Unlike the cardiac system, respiratory rhythm is not produced by a homogeneous population of pacemaker cells.
