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.
anterior cranial fossa: foramen cecum: 1: emissary veins to superior sagittal sinus from the upper part of the nose [3] ethmoid: anterior cranial fossa (osama) foramina of cribriform plate ~20-olfactory nerve bundles (I) ethmoid: anterior cranial fossa: anterior ethmoidal foramen: 2: anterior ethmoidal artery anterior ethmoidal vein: anterior ...
There are two important foramina in the palatine bones that transmit nerves and blood vessels to this region: the greater and lesser palatine. The larger greater palatine foramen is located in the posterolateral region of each of the palatine bones, usually at the apex of the maxillary third molar. The greater palatine foramen transmits the ...
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.
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.
posterior: root of the pterygoid process and adjoining anterior surface of the greater wing of sphenoid bone; medial: perpendicular plate of the palatine bone and its orbital and sphenoidal processes; lateral: pterygomaxillary fissure; inferior: part of the floor is formed by the pyramidal process of the palatine bone.
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 ...
The facial skeleton comprises the facial bones that may attach to build a portion of the skull. [1] The remainder of the skull is the neurocranium.. In human anatomy and development, the facial skeleton is sometimes called the membranous viscerocranium, which comprises the mandible and dermatocranial elements that are not part of the braincase.
