Incisive canals
Encyclopedia
In the opening of the incisive foramen
, the orifices of two lateral canals are visible; they are named the incisive canals or foramina of Stensen
.
Through each of them passes the terminal branch of the descending palatine artery
and the nasopalatine nerve
, to communicate with posterior septal branch
of sphenopalatine artery
and greater palatine nerve
respectively.

Descending palatine artery
-Course:It descends through the pterygopalatine canal with the anterior palatine branch of the sphenopalatine ganglion, and, emerging from the greater palatine foramen, runs forward in a groove on the medial side of the alveolar border of the hard palate to the incisive canal; the terminal branch...

Posterior septal branches of sphenopalatine artery
Crossing the under surface of the sphenoid the sphenopalatine artery ends on the nasal septum as the posterior septal branches; these anastomose with the ethmoidal arteries and the septal branch of the superior labial; one branch descends in a groove on the vomer to the incisive canal and...
