GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -The muscle has its origin from the inferior surface of the palatine aponeurosis. It descends along with the muscle of the contralateral side in an inferior, forward, and lateral direction anterior to the palatine tonsil and gets inserted into the posterolateral surface of the tongue.

Detailed explanation-3: -The incisive foramen is located in the anterior midline of the hard palate. This structure is located just below the incisive papilla, a fleshy convexity on the palatal mucosa. The incisive foramen transmits the terminal branches of the nasopalatine nerve and the sphenopalatine arteries and veins.
