The incisive foramen is a funnel-shaped opening in the bone of the oral hard palate representing the inferior termination of the incisive canal. [citation needed] An oral prominence - the incisive papilla - overlies the incisive fossa. [1] The incisive foramen is situated immediately behind the incisor teeth, and in between the two premaxillae.
Anaesthetic injected near the mandibular foramen to block the inferior alveolar nerve and the nearby lingual nerve (supplying the tongue). This causes loss of sensation on the same side as the block to: the teeth (inferior alveolar nerve block) the lower lip and chin (mental nerve block) front two-thirds of the tongue (lingual nerve block).
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.
The nasopalatine nerve (also long sphenopalatine nerve [1]: 496 ) is a nerve of the head. It is a sensory branch of the maxillary nerve (CN V 2) that passes through the pterygopalatine ganglion (without synapsing) and then through the sphenopalatine foramen to enter the nasal cavity, and finally out of the nasal cavity through the incisive canal and then the incisive fossa to enter the hard ...
When the two maxillae are articulated, a funnel-shaped opening, the incisive foramen, is seen in the middle line, immediately behind the incisor teeth. In this opening the orifices of two lateral canals are visible; they are named the incisive canals or foramina of Stenson ; through each of them passes the terminal branch of the descending ...
When Teresa Regula arrived at Auschwitz as a 16-year-old, the first real pain she experienced was of her ears burning. "They shaved us down to bare skin, and it was a scorching hot day, August 4 ...
Radwah Oda was diagnosed with colon cancer at 30. She shares five symptoms she dismissed, including narrow stools, blood in the stool, pain and fatigue.
Historically, the cause of nasopalatine duct cysts has been somewhat of an enigma. Although it was originally postulated that the cyst formed from trapped epithelial cells during embryonic fusion of the palatal bones, [3] it is now thought that it forms from oronasal ducts present within the incisive canals.
