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 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 .
The levator veli palatini (/ l ɪ ˈ v eɪ t ər ˈ v iː l aɪ ˌ p æ l ə ˈ t aɪ n aɪ /) is a muscle of the soft palate and pharynx.It is innervated by the vagus nerve (cranial nerve X) via its pharyngeal plexus.
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 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.
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
The stapedius muscle, the smallest skeletal muscle in the body, connects to the stapes and is controlled by the facial nerve; the tensor tympani muscle is attached to the upper end of the medial surface of the handle of malleus [2] and is under the control of the medial pterygoid nerve which is a branch of the mandibular nerve of the trigeminal ...
This also supplies the tensor tympani muscle and the tensor veli palatini muscle. The medial pterygoid nerve is a main trunk from the mandibular nerve, before the division of the trigeminal nerve - this is unlike the lateral pterygoid muscle, and all other muscles of mastication which are supplied by the anterior division of the mandibular nerve.
