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 medial pterygoid nerve supplies the medial pterygoid muscle, tensor tympani muscle, and tensor veli palatini muscle (via the nerve to tensor veli palatini). [1]The tensor veli palati muscle is the only of the five paired skeletal muscles to the soft palate not innervated by the pharyngeal plexus.
It is the superior origin of the pterygomandibular raphe, and the levator veli palatini muscle. ... The tendon of tensor veli palatini muscle glides around it. [1]
It serves as the insertion for the tensor veli palatini and levator veli palatini, and the origin for the musculus uvulae, palatopharyngeus, and palatoglossus. [4] The palatine aponeurosis is attached to the posterior margin of the hard palate. [2] [5] It is thicker anteriorly and thiner posteriorly. Posteriorly, it blends with the posterior ...
The nerve to tensor veli palatini is a small nerve which is unique in that it is the only branch of the mandibular nerve providing motor innervation to the palate.
The mandibular nerve immediately passes between tensor veli palatini, which is medial, and lateral pterygoid, which is lateral, and gives off a meningeal branch (nervus spinosus) and the nerve to medial pterygoid from its medial side. The nerve then divides into a small anterior division and a large posterior division.
A tensor muscle has the function of tensing (stretching or tightening) a part and may refer to: Tensor fasciae latae muscle; Tensor tympani muscle; Tensor vastus intermedius muscle; Tensor veli palatini muscle
