palatine aponeurosis

Attached to the posterior border of the hard palate is a thin, firm fibrous lamella called the palatine aponeurosis, which supports the muscles and gives strength to the soft palate. It is thicker above than below, where it becomes very thin and difficult to define. Laterally it is continuous with the pharyngeal aponeurosis. It serves as the insertion for the Tensor veli palatini and Levator veli palatini, and the origin for the Musculus uvulae, Palatopharyngeus, and Palatoglossus. It provides support for the soft palate.
