palatoglossal การใช้

The anterior one is known as the palatoglossal arch, and the posterior one is known as the palatopharyngeal arch.
Each palatoglossal arch runs downwards, laterally and forwards, from the soft palate to the side of the tongue.
Once the bolus reaches the palatoglossal arch of the oropharynx, the pharyngeal phase, which is reflex and involuntary, then begins.
They are scattered over the base of the tongue, the palatoglossal and palatopharyngeal arches, the tonsillar fossa, uvula and posterior pharyngeal wall.
The approximation of the arches due to the contraction of the palatoglossal muscles constricts the isthmus, and is essential to swallowing ( deglutition ).
