The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone.It forms a partition between the nasal passages and the mouth.On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once ...
In the human mouth, the incisive foramen (also known as: "anterior palatine foramen", or "nasopalatine foramen") is the opening of the incisive canals on the hard palate immediately behind the incisor teeth. It gives passage to blood vessels and nerves. The incisive foramen is situated within the incisive fossa of the maxilla.
The greater palatine foramen transmits the greater palatine nerve and blood vessels. A smaller opening nearby, the lesser palatine foramen, transmits the lesser palatine nerve and blood vessels to the soft palate and tonsils. Both foramina are openings of the pterygopalatine canal that carries the descending palatine nerves and blood vessels ...
The two incisive canals usually (in 60% of individuals) have a characteristic Y-shaped or V-shaped morphology: above, each incisive canal opens into the nasal cavity on either side of the nasal septum as the nasal foramina; below, the two incisive canals converge medially to open into the oral cavity at midline at the incisive fossa [1] as several incisive foramina.
It is perforated by numerous foramina for the passage of the nutrient vessels; is channelled at the back part of its lateral border by a groove, sometimes a canal, for the transmission of the descending palatine vessels and the anterior palatine nerve from the spheno-palatine ganglion; and presents little depressions for the lodgement of the palatine glands.
Its roof is formed by the hard palate. The floor is formed by the mylohyoid muscles and is occupied mainly by the anterior two-thirds of the tongue . A mucous membrane – the oral mucosa , lines the sides and under surface of the tongue to the gums , and lines the inner aspect of the jaw ( mandible ).
In humans, the upper jaw includes the hard palate in the front of the mouth. [3] [4] The two maxillary bones are fused at the intermaxillary suture, forming the anterior nasal spine. This is similar to the mandible (lower jaw), which is also a fusion of two mandibular bones at the mandibular symphysis. The mandible is the movable part of the jaw.
It is sometimes known as the major palatine foramen. The greater palatine foramen functions primarily for the transmission of the descending palatine vessels and greater palatine nerve ; running anteriorly (forward) and medially (towards the center-line) from it is a groove, for the same vessels and nerve.
