Lesser Palatine Foramen
Behind the greater palatine foramen is the pyramidal process of the palatine bone, perforated by one or more lesser palatine foramina which carry the lesser palatine nerve, and marked by the commencement of a transverse ridge, for the attachment of the tendinous expansion of the tensor veli palatini. See also * Greater palatine foramen At either posterior angle of the hard palate is the greater palatine foramen, for the transmission of the descending palatine vessels and greater palatine nerve; and running anteriorly (forward) and medially (towards the center-line) from it is a g ...

Greater Palatine Foramen
At either posterior angle of the hard palate is the greater palatine foramen, for the transmission of the descending palatine vessels and greater palatine nerve; and running anteriorly (forward) and medially (towards the center-line) from it is a groove, for the same vessels and nerve. Variations The greater palatine foramen (GPF) is related to the upper 3rd molar tooth in most of the skulls (55%), 2nd molar in (12%), between the 2nd and 3rd molar in (19%) and retromolar in (14%). The shape of the foramen is elongated antero-posteriorly; however, an unusually crescent shaped foramen is rare.

Pyramidal Process Of Palatine Bone
The pyramidal process of the palatine bone projects backward and lateralward from the junction of the horizontal and vertical parts, and is received into the angular interval between the lower extremities of the pterygoid plates. On its posterior surface is a smooth, grooved, triangular area, limited on either side by a rough articular furrow. The furrows articulate with the pterygoid plates, while the grooved intermediate area completes the lower part of the pterygoid fossa and gives origin to a few fibers of the Pterygoideus internus The medial pterygoid muscle (or internal pterygoid muscle), is a thick, quadrilateral muscle of the face. It is supplied by the mandibular branch of the trigeminal nerve (V). It is important in mastication (chewing). Structure The medial pter .... The anterior part of the lateral surface is rough, for articulation with the tuberosity of the maxilla; its posterior part consists of a smooth triangular area which appears, in the articulated skul ...

Lesser Palatine Nerve
The lesser palatine nerves (posterior palatine nerve) are branches of the maxillary nerve (CN V2). They descends through the greater palatine canal alongside the greater palatine nerve, and emerge (separately) through the lesser palatine foramen to pass posteriorward. They supply the soft palate, tonsil, and uvula. See also *Greater palatine nerve The greater palatine nerve is a branch of the pterygopalatine ganglion. This nerve is also referred to as the anterior palatine nerve, due to its location anterior to the lesser palatine nerve. It carries both general sensory fibres from the maxi ...

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] |
