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.
MASTICATION
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.
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.
Deglutition, or swallowing, consists of three stages: oral, pharyngeal, and esophageal. During the oral stage, the food is chewed and formed into a bolus before being voluntarily pushed to the back of the mouth. In the pharyngeal stage, the swallow reflex is triggered to move the bolus through the pharynx and into the esophagus. Finally, in the esophageal stage, peristalsis helps transport the food down the esophagus and into the stomach.
The larynx
Thyrohyoid is a suprahyoid muscle and it depresses the larynx , it also helps in swallowing and deglutition , some Indian books state that is an elevator of the larynx , but most literature that i have read states it to be a depressor , other depressors of the larynx are omohyoid , sternohyoid and sternothyrohyoid.
The process of swallowing is called deglutition. It involves voluntary and involuntary muscles working together to move food or liquid from the mouth to the stomach.
MASTICATION
The Pharyngeal stage of deglutition - 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

Yes, deglutition is the medical term for swallowing.
No, deglutition and mastication are not synonyms. Mastication refers to the process of chewing food to break it down into smaller pieces, while deglutition refers to the process of swallowing food after it has been chewed.
