The incisive foramen allows for blood vessels and nerves to pass. These include: the pterygopalatine nerves to the hard palate. [2] the nasopalatine nerves from the floor of the nasal cavity. [3] the sopalatine branches of the infratrochlear nerve, a branch of the ophthalmic nerve (V1), itself a branch of the trigeminal nerve. [4]
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 ...
In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest. It is the most important bone in the midface. It provides structural support for the ...

The sphenopalatine foramen is the opening between the sphenoid bone and orbital processes of the palatine bone; it opens into the nasal cavity and gives passage to branches from the pterygopalatine ganglion and the sphenopalatine artery from the maxillary artery.
In the maxilla, occasionally two additional canals are present in the middle line of the palatine process; they are termed the foramina of Scarpa, and when present transmit the nasopalatine nerves, the left passing through the anterior, and the right through the posterior canal.
It emerges upon the hard palate through the greater palatine foramen. It then passes forward in a groove in the hard palate, nearly as far as the incisor teeth. While in the pterygopalatine canal , it gives off lateral posterior inferior nasal branches , which enter the nasal cavity through openings in the palatine bone , and ramify over the ...
