Detailed explanation-1: -The medulla oblongata is a part of the hindbrain and controls the involuntary activities of the body like coughing, sneezing and swallowing.
Detailed explanation-2: -Manages heart, circulation and breathing. Your medulla is where your cardiovascular and respiratory systems link together into a united system that controls your heart rate, breathing, blood pressure and more. Manages other automatic processes.
Detailed explanation-3: -The sneezing reflex may be divided in two phases. The first is a nasal or sensitive phase, following stimulation of the nasal mucosa by chemical or physical irritants. The afferent pathways are through the olfactory and ethmoidal nerves, which converge in the putative “sneezing centre” in the medulla.
Detailed explanation-4: -The area postrema (AP) has been implicated as a chemoreceptor trigger zone for vomiting (emesis) for over 40 years. The AP is located on the dorsal surface of the medulla oblongata at the caudal end of the fourth ventricle.
