Nerve To Tensor Veli Palatini
The nerve to tensor veli palatini is a small nerve which is unique in that it is the only branch of the mandibular nerve In neuroanatomy, the mandibular nerve (V) is the largest of the three divisions of the trigeminal nerve, the fifth cranial nerve (CN V). Unlike the other divisions of the trigeminal nerve (ophthalmic nerve, maxillary nerve) which contain only aff ... providing motor innervation to the palate. Mandibular nerve {{neuroanatomy-stub ...

Tensor Veli Palatini
The tensor veli palatini muscle (tensor palati or tensor muscle of the velum palatinum) is a broad, thin, ribbon-like muscle in the head that tenses the soft palate. Structure The tensor veli palatini is found anterior-lateral to the levator veli palatini muscle. It arises by a flat lamella from the scaphoid fossa at the base of the medial pterygoid plate, from the spina angularis of the sphenoid and from the lateral wall of the cartilage of the auditory tube. Descending vertically between the medial pterygoid plate and the medial pterygoid muscle, it ends in a tendon which winds around the pterygoid hamulus, being retained in this situation by some of the fibers of origin of the medial pterygoid muscle. Between the tendon and the hamulus is a small bursa. The tendon then passes medially and is inserted into the palatine aponeurosis and into the surface behind the transverse ridge on the horizontal part of the palatine bone. Nerve supply The tensor veli palatini muscle is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medial Pterygoid Nerve
The medial pterygoid nerve (or internal pterygoid nerve) is a nerve of the head. It is a branch of the mandibular nerve (CN V3). It supplies the medial pterygoid muscle, the tensor veli palatini muscle, and the tensor tympani muscle. Structure The medial pterygoid nerve is a slender branch of the mandibular nerve (CN V3), itself a branch of the trigeminal nerve (CN V). It is the first branch of the mandibular nerve. It enters the deep surface of the medial pterygoid muscle. It passes through the otic ganglion without synapsing, so is neurologically distinct. However, it provides physical support. The medial pterygoid nerve receives some motor fibres from the otic ganglion. Function The medial pterygoid nerve supplies the medial pterygoid muscle. It also supplies tensor veli palatini muscle, through the nerve to tensor veli palatini, one of its branches. Of the five paired skeletal muscles to the soft palate, tensor veli palati muscle is the only muscle not innervated by the ...

Mandibular Nerve
In neuroanatomy, the mandibular nerve (V) is the largest of the three divisions of the trigeminal nerve, the fifth cranial nerve (CN V). Unlike the other divisions of the trigeminal nerve (ophthalmic nerve, maxillary nerve) which contain only afferent fibers, the mandibular nerve contains both afferent and efferent fibers. These nerve fibers innervate structures of the lower jaw and face, such as the tongue, lower lip, and chin. The mandibular nerve also innervates the muscles of mastication. Structure The large sensory root emerges from the lateral part of the trigeminal ganglion and exits the cranial cavity through the foramen ovale. Portio minor, the small motor root of the trigeminal nerve, passes under the trigeminal ganglion and through the foramen ovale to unite with the sensory root just outside the skull. The mandibular nerve immediately passes between tensor veli palatini, which is medial, and lateral pterygoid, which is lateral, and gives off a meningeal branch (n ...
