GENERAL HISTOLOGY

Detailed explanation-1: -The palatoglossus and palatopharyngeus muscles extend from the palate down the sides of the airway (palatoglossus in front and palatopharyngeus behind the tonsil) to the base of the tongue and alter the position of the soft palate relative to the tongue and pharynx, respectively (Fig. 1).

Detailed explanation-2: -The space between the tongue and palatoglossal and palatopharyngeal arches is called the tonsillar fossa (sinus), and it is where the palatine tonsils are located.

Detailed explanation-3: -Palatopharyngeus muscle originates from the posterior border of hard palate and palatine aponeurosis. The originating fibers are divided by the levator veli palatini muscle into anterior and posterior fascicles or layers, which converge into a compact muscle belly at the posterolateral border of soft palate.

Detailed explanation-4: -The palatoglossus muscle, also known as musculus palatoglossus, is among the four extrinsic muscles of the tongue and the paired muscles of the soft palate. The right and left palatoglossus muscles create ridges in the lateral pharyngeal wall, referred to as the palatoglossal arches (anterior faucial pillars).
