Document Summary
A patterned motor response" that moves material through the digestive tract - from mouth to esophagus. Highly stereotyped motor behaviour, that can be modified by sensory feedback. Once it gets into the throat, this is here the pattern happens for motor pathway. When it gets to the throat or pharynx, large changes are happening to the larynx (voice box) Salivary amylase begins the breakdown of starch in the mouth. Buccal phase is the first phase, it is voluntary. Supportive function: transports ingested material from mouth to stomach. Protective function: protects respiratory system from entry of foreign material. Need a change in anatomy to protect our airway. In the adult human, the upper respiratory and digestive paths are crossed. Crossroads is called the upper aerodigestive tract . Tongue, teeth, mandible all responsible for getting food ready to swallow. They work together to prepare food so that it is ready to be swallowed.
