What is "mandibular canal"

In human anatomy, the mandibular canal is a canal within the mandible that contains the inferior alveolar nerve, inferior alveolar artery, and inferior alveolar vein. It runs obliquely downward and forward in the ramus, and then horizontally forward in the body, where it is placed under the alveoli and communicates with them by small openings.

On arriving at the incisor teeth, it turns back to communicate with the mental foramen, giving off a small canal known as the mandibular incisive canal, which run to the cavities containing the incisor teeth.

It carries branches of the inferior alveolar nerve and artery.

It is continuous with the mental foramen (which opens onto front of mandible) and mandibular foramen (on medial aspect of ramus).
