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 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 ...
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 (medial and lateral) posterior superior nasal nerves are branches of the maxillary nerve (CN V2) [3]: 496 that arise in the pterygopalatine fossa from pterygopalatine ganglion [3]: 369–370 and pass through the sphenopalatine foramen into the nasal cavity [3]: 496 to innervate the nasal septum (the medial nerves), and the posterosuperior portion of the lateral wall of the nasal cavity ...
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.
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 maxillary nerve (CN V 2, the second division of the trigeminal nerve), with which is the nerve of the pterygoid canal, a combination of the greater petrosal nerve (preganglionic parasympathetic) and the deep petrosal nerve (postganglionic sympathetic). To obtain block anesthesia of the entire second division of the trigeminal nerve, an ...
