The levator veli palatini is the primary elevator of the palate.
Clefts of the secondary palate are due to lack of fusion of the palatal shelves, and always occur posterior to the incisive foramen.
In palatal clefts, the muscles of the softpalate are hypoplastic and insert in the posterior margin of the remaining hard palate rather than the midline raphe.
Palate, roof of the mouth, consisting of two portions, the hard palate in front and the softpalate behind.
The softpalate is a movable fold of mucous membrane enclosing muscular fibres; its sides blend with the pharynx, but its lower border is free.
It is suspended from the rear of the hard palate so as to form an incomplete wall or division between the mouth and the pharynx that, in swallowing, is raised to close the entrance to the nasal passages.
