When the two maxillæ are articulated, a funnel-shaped opening, the incisive foramen, is seen in the middle line, immediately behind the incisor teeth.
Continuous with the incisive canal, this foramen or group of foramina are located posterior to the central incisor teeth in the incisive fossa of the maxilla. The incisive foramen receives the nasopalatine nerves from the floor of the nasal cavity along with the sphenopalatine arteries supplying the oral mucosa covering the hard palate of the mouth
