Dissection of the muscles of the palate from behind. The five muscles of the soft palate play important roles in swallowing and breathing. The muscles are: Tensor veli palatini, which is involved in swallowing; Palatoglossus, involved in swallowing; Palatopharyngeus, involved in breathing; Levator veli palatini, involved in swallowing
The tensor veli palatini muscle receives motor innervation from the mandibular nerve (CN V 3) (a branch of the trigeminal nerve (CN V)) [2] via the nerve to medial pterygoid. [1] It is the only muscle of the palate not innervated by the pharyngeal plexus, which is formed by the vagal and glossopharyngeal nerves. [citation needed]
The levator veli palatini muscle elevates the soft palate during swallowing. This helps to prevent food from entering the nasopharynx. Its action may be slightly slower than its partner, the tensor veli palatini muscle. [1] It has little to no effect on the pharyngotympanic tube. [2]
The muscle is situated in between the two laminae of the palatine aponeurosis. From its origin, it passes posterior-ward superior to the swing that is formed by the levator veli palatini muscle . The musculus uvulae and levator veli palatini muscle form a right angle so that their contraction elevates the levator eminence to aid in separating ...
The palatine velum is slightly raised by the levator veli palatini and made tense by the tensor veli palatini; the palatopharyngeus muscles, by their contraction, pull the pharynx upward over the bolus of food and nearly come together, the uvula filling up the slight interval between them.
Veau-III cleft palate: A cleft of the velum (soft palate), extending unilaterally through the secondary hard palate, past the incisive foramen, and through the primary hard palate and alveolus. The vomer (the bony part of the nasal septum) remains attached to the palatal shelf on the greater segment (non-cleft side).

The velum—or soft palate—controls airflow through the nasal cavity. Nasals and nasalized sounds are produced by lowering the velum and allowing air to escape through the nose. Vowels are normally produced with the soft palate raised so that no air escapes through the nose.
