Bone: Incisive canals

The bony palate and alveolar arch. (Incisive canals labeled at upper left.)
Latin	canales incisivi
Gray's	subject #38 162
Dorlands / Elsevier	c_04/12208639

In the opening of the incisive foramen, the orifices of two lateral canals are visible; they are named the incisive canals or foramina of Stenson.

Through each of them passes the terminal branch of the descending palatine artery and the nasopalatine nerve.
