Deglutition, or swallowing, can be divided into three stages. The oral, pharyngeal and oesophageal stages.
Oral stage - the bolus of food is prepared --> the apex of the tongue presses on the palate --> rapid contraction of mylohyoideus and extrinsic muscles of the tongue propel the food (bolus) to the pharynx.
Pharyngeal stage - the bolus hits the pharynx and triggers reflexes (from this point it is no longer voluntary) --> the soft palate is raised, the glottis closed and the pharynx shortened --> pharyngeal constrictors move bolus into the oesophagus
Oesophageal stage - peristalsis moves the bolus to the stomach
