The soft palate (also known as the velum, palatal velum, or muscular palate) is, in mammals, the soft tissue constituting the back of the roof of the mouth. The soft palate is part of the palate of the mouth; the other part is the hard palate .
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 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.
The plexus provides motor innervation to most muscles of the soft palate (all but the tensor veli palatini muscle) and most muscles of the pharynx (all but the stylopharyngeus muscle). [1] The larynx meanwhile receives motor innervation from the vagus nerve (CN X) via its external branch of the superior laryngeal nerve and its recurrent ...
Veau-IV cleft palate: A cleft of the velum (soft palate), extending in the midline through the secondary hard palate up to the incisive foramen and then bilaterally through the primary hard palate and alveolus on each side. The vomer (the bony part of the nasal septum) remains in the midline and is attached to the premaxilla.
It is a narrow passage between the velum and the base of the tongue. [2] The fauces is a part of the oropharynx directly behind the oral cavity as a subdivision, bounded superiorly by the soft palate, laterally by the palatoglossal and palatopharyngeal arches, and inferiorly by the tongue. The arches form the pillars of the fauces.
