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.
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. [citation needed]
Muscles of mastication, anterior belly of the digastric, mylohyoid, tensor tympani, tensor veli palatini: Premaxilla, maxilla, mandible (only as a model for mandible not actual formation of mandible), zygomatic bone, part of the temporal bone, [19] the incus, and the malleus of the middle ear, also Meckel's cartilage and the sphenomandibular ...
They are vasomotor in function. The sensory root comes from the auriculotemporal nerve and is sensory to the parotid gland . The motor fibers supplying the medial pterygoid and the tensor veli palatini and the tensor tympani pass through the ganglion without relay.
The tensor tympani is a muscle within the middle ear, located in the bony canal above the bony part of the auditory tube, and connects to the malleus bone. Its role is to dampen loud sounds, such as those produced from chewing , shouting, or thunder .
Tensor veli palatini, which is involved in swallowing; Palatoglossus, involved in swallowing; Palatopharyngeus, involved in breathing; Levator veli palatini, involved in swallowing; Musculus uvulae, which moves the uvula; These muscles are innervated by the pharyngeal plexus via the vagus nerve, with the exception of the tensor veli palatini.
The sensory function of the trigeminal nerve is to provide tactile, proprioceptive, and nociceptive afference to the face and mouth. Its motor function activates the muscles of mastication, the tensor tympani, tensor veli palatini, mylohyoid and the anterior belly of the digastric.
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.
