Where is the incisive fossa located in the mouth?
The sphenopalatine nerve (a branch of the maxillary nerve V2) carries post ganglionic parasympathetic fibres from the sphenopalatine ganglion via the foramen into the nasal cavity. It passes down the lateral wall of the septum to reach the upper opening of the incisive foramen. View chapter Purchase book.
What passes through the palatine foramen?
Feb 11, 2022 · URL of Article. The incisive foramen (also known as nasopalatine foramen or anterior palatine foramen) is the oral opening of the nasopalatine canal.

What cranial nerve passes through the incisive foramen?
A terminal branch of the maxillary nerve (CN V3), the nasopalatine nerve, runs from the nasal cavity, through the incisive canal and supplies the tissues of the anterior part of the hard palate.
What runs through the incisive canal?
The maxillary incisive canal runs through the maxilla in the midline. It connects the inferior nasal cavity with the superior oral cavity, opening at the incisive foramen posterior to the central maxillary incisor teeth. It contains the descending palatine artery and the nasopalatine nerve.Oct 5, 2021
What is the function of incisive papilla?
The incisive papilla is a landmark within the edentulous maxilla that is used for arranging maxillary anterior teeth in denture prostheses, and can be best described by being lingual to and between the natural central incisors.
Where is the location of incisive foramen?
bony palateThe incisive foramen (IF) lies in the bony palate, directly behind the first two incisors, in the incisive fossa (Fig. 11.3). It carries the sphenopalatine artery and the nasopalatine nerve from the nasal cavity through the bony palate via the incisive canal (IC) (Fig. 11.4).Jan 24, 2019
What is the nasopalatine foramen?
Anatomical terms of bone. In the human mouth, the incisive foramen, also called anterior palatine foramen, or nasopalatine foramen is a funnel-shaped opening in the bone of the oral hard palate immediately behind the incisor teeth where blood vessels and nerves pass.
What is the incisive foramen?
Incisive foramen. The bony palate and alveolar arch. In the human mouth, the incisive foramen, also called anterior palatine foramen, or nasopalatine foramen is a funnel-shaped opening in the bone of the oral hard palate immediately behind the incisor teeth where blood vessels and nerves pass. The incisive foramen is continuous with ...
Which nerves are sent to the incisive foramen?
The incisive foramen receives the nasopalatine nerves from the floor of the nasal cavity along with the sphenopalatine artery supplying the mucous membrane covering the hard palate of the mouth. In many other species, the incisive foramina allow for passage of ducts to the vomeronasal organ .
Overview
In the human mouth, the incisive foramen, also called anterior palatine foramen, or nasopalatine foramen, is a funnel-shaped opening in the bone of the oral hard palate. It is immediately behind the incisor teeth. The incisive foramen is continuous with the incisive canal, located behind the central incisor teeth in the incisive fossa of the maxilla. It allows for blood vessels and nerves to pass. It i…
Structure
The incisive foramen is a funnel-shaped opening in the bone of the oral hard palate. It is immediately behind the incisor teeth. It is also between the premaxillae on each side. It is continuous with the incisive canal, located behind the central incisor teeth in the incisive fossa of the maxilla.
Function
The incisive foramen allows for blood vessels and nerves to pass. These include:
• the pterygoopalatine nerves to the hard palate.
• the nasopalatine nerves from the floor of the nasal cavity.
• the sopalatine branches of the infratrochlear nerve, a branch of the ophthalmic nerve (V1), itself a branch of the trigeminal nerve.
Clinical significance
As many nerves exit the incisive canal at the incisive foramen, it may be used for injection of local anaesthetic.
When plain radiographs are taken of the mouth, the incisive foramen may be mistaken for a periapical lesion.
The incisive foramen can be used as a landmark when describing cleft lip and cleft palate, whic…
History
The incisive foramen is also known as the anterior palatine foramen, the nasopalatine foramen, and the incisive fossa.
Other animals
In many other species, the incisive foramina allow for passage of ducts to the vomeronasal organ. It can be found in cats, and alligators.
