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: -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.
