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 cranial region includes the upper part of the head while the; facial region includes the lower half of the head beginning below the ears.; The forehead is referred to as the frontal region.
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.
This is a category for the collection of subcategories of muscles by where they rest in various body locations. Subcategories This category has the following 4 subcategories, out of 4 total.
The palatoglossus elevates the root of the tongue (i.e. the posterior attached portion of the tongue [citation needed]).It approximates the ipsilateral (same side) palatoglossal arch to the contralateral (opposite side) one, thus separating the oral cavity and the oropharynx.
The frenulum veli, or frenulum of superior medullary velum, also known as the frenulum veli medullaris superioris, cerebellar frenulum, or frenulum cerebelli, is a slightly raised white band passing from the inferior end of the medial longitudinal fissure, through the groove between the quadrigeminal bodies, and down to the superior medullary velum.
