Origin

The palatopharyngeus muscle consists of two muscular bundles that originate from the horizontal plate of palatine bone and the upper portion of the palatine aponeurosis. The muscular bundles are separated by the levator veli palatini muscle (Standring, 2016).

Insertion

The two muscular bands of the palatopharyngeus muscle merge at the posterolateral border of the soft palate, where they also blend with the salpingopharyngeus muscle. It inserts into the lateral aspect of the pharynx and the posterior aspect of the thyroid cartilage (Standring, 2016).

Key Features & Anatomical Relations

The palatopharyngeus muscle and its overlying mucosal layer form the palatopharyngeal arches (palatopharyngeal fold or posterior pillar/column of fauces) on either side of the oropharynx.

Actions

The palatopharyngeus muscle pulls the pharynx in superior, anterior and medial directions. This action is used when swallowing. The palatopharyngeus muscle tenses the soft palate by drawing the palatopharyngeal arches anteriorly (Standring, 2016).

The longitudinal muscles are the stylopharyngeus, salpingopharyngeus, and palatopharyngeus muscles, and they elevate and shorten the pharynx during swallowing.
