What does the tensor palatini muscle do?
Function. The tensor veli palatini tenses the soft palate and by doing so, assists the levator veli palatini in elevating the palate to occlude and prevent entry of food into the nasopharynx during swallowing.
What is the tensor veli palatini?
The tensor veli palatini is a flat, fusiform muscle that, like the levator, attaches to the petrous part of the temporal bone, the pterygoid bones, and the lateral lamina of the guttural pouch. 51. Its tendon is reflected around the hamulus of the pterygoid bone, where it is lubricated by a bursa.
What nerve Innervates tensor veli palatini muscle?
the mandibular nerve
This muscle’s innervation is by the motor part of the mandibular nerve. The mandibular nerve is CNV3 of the trigeminal nerve. [6][5] This nerve also supplies the medial pterygoid. [10] The medial pterygoid and the TVP can work together to open the Eustachian tube and play a role in mastication.
What is the action of the levator veli palatini?
action: elevates and laterally deviates the soft palate. It also aids the tensor veli palatini muscle in opening the Eustachian tube on swallowing to allow pressure equalization of pressure between the middle ear and pharynx. innervation: pharyngeal plexus (from vagus nerve (CN X))
What does Veli mean in anatomy?
Veli means veil as in a bride’s veil. palatini means “of the palate” or roof of the mouth. Musculus Tensor Veli Palatini = the muscle that stretches the veil of the palate (tenses soft palate before elevation)
Where is tensor veli palatini located?
| Levator veli palatini | |
|---|---|
| Origin | temporal bone, Eustachian tube |
| Insertion | palatine aponeurosis |
| Artery | facial artery |
| Nerve | Pharyngeal Branch of Vagus (CN X) |
Which cranial nerve is responsible for innervating the tensor veli palatini that tenses the soft palate and facilitates bolus hold?
The tensor veli palatini is innervated by the mandibular nerve.
What is the uvula innervated by?
The uvula is supplied by branches of the arteries that supply the soft palate: ascending palatine artery. palatine branch of the ascending pharyngeal artery. greater palatine branch of the internal maxillary artery.
What do you mean by Velli?
velli. Future Athlete. Born to be an athlete.
The tensor veli palatini is a flat, fusiform muscle that travels with the levator veli palatini muscle along the lateral walls of the nasopharynx and the lateral lamina of the guttural pouch ( Sisson 1975a ). Its tendon is reflected around the hamulus of the pterygoid bone, where it is lubricated by a bursa.
Which muscle is not innervated by the pharyngeal plexus?
Thereby, tensor veli palatini is the only muscle of the soft palate that is not innervated by the pharyngeal plexus, formed by the vagus nerve (CN X). Tensor veli palatini receives arterial blood supply from the greater palatine branch of the maxillary artery, as well as the ascending palatine branch of the facial artery.
What is tensor tympani syndrome?
Tensor tympani syndrome, also known as the tensor tympani myoclonus, is a rare form of objective pulsatile tinnitus, which includes tensor tympani-associated tinnitus caused by the contraction of the tensor tympani (TT) muscle.
What is the function of the tympanic membrane during contraction?
During contraction, the TT functions to open the eustachian tube and pull the malleus medially, which subsequently stiffens the tympanic membrane and decreases the propagation of sound throughout the ossicular chain. The TT muscle, tensor veli palatini, and muscles of mastication are all innervated by the trigeminal nerve.
