Where does deglutition occur?

Deglutition, or swallowing, occurs in the oropharynx and upper esophagus. The process begins voluntarily in the mouth and is then carried out involuntarily as the food or liquid passes through the pharynx and into the esophagus on its way to the stomach.


What is the muscular organ responsible for initiating deglutition?

The tongue is the muscular organ responsible for initiating deglutition, or swallowing. It helps to move food towards the back of the mouth and into the pharynx, which then triggers the swallowing reflex.


What are the stages of deglutition?

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 oesophagusOesophageal stage - peristalsis moves the bolus to the stomach


Why do larynx move with deglutition?

The larynx moves during the swallowing process, or deglutition, to protect the airway from food and liquid entering the lungs. This movement helps to close off the entrance to the trachea (windpipe) by raising the larynx and epiglottis, preventing aspiration of food or liquid into the respiratory system.
