It attaches superiorly to the hard palate and palatine aponeurosis and inferiorly to the lateral wall of the pharynx. Its function is to tense the soft palate and pull the pharyngeal walls superiorly, anteriorly, and medially during swallowing, effectively closing off the nasopharynx from the oropharynx.
What is the Palatopharyngeus muscle?
The palatopharyngeus muscle is a muscle of the head and neck, and one of the inner longitudinal muscles of the pharynx. It is also referred to as one of the five paired muscles of the soft palate. The paired muscles create ridges of mucous membrane in the lateral pharyngeal wall called the palatopharyngeal arches.
What muscle makes up the uvula?
musculus uvulae muscle
The musculus uvulae muscle derives from the palatine aponeurosis and the posterior nasal spine and attaches to the mucous membrane of the uvula. The musculus uvulae muscle functions to shorten the uvula. Ipsilateral contraction of the musculus uvulae muscle draws up the uvula on the same side.
What is palatopharyngeus innervated?
Innervation. Palatopharyngeus muscle is innervated by branches of pharyngeal plexus, which in turn receives input from the vagus nerve (CN X).
What is Palatopharyngeus innervated?
What muscle depresses the velum?
Depression of the soft palate is achieved through the contraction of the palatoglossus and palatopharyngeus muscles. These muscles form the body of the faucal pillars from which the uvula hangs and were observed during the dissection of the tongue.
Where is palatopharyngeus muscle?
pharynx
The palatopharyngeus is a muscle of both the soft palate and the pharynx. Anteriorly, the muscle fibers are attached to the hard palate, and posterior fibers are attached to the palatine aponeurosis. The anterior portion of the muscle is separated by the levator veli palatini (LVP).
