mandibular canal

The human mandible represents one of the most fascinating structures in oral anatomy, combining both functional necessity and structural complexity. This cutaway view of the mandibula reveals the intricate architecture of spongy bone (also known as cancellous or trabecular bone) that lies beneath the dense cortical layer of the mandible.

This anatomical illustration provides a unique sectional view of the permanent teeth from the right side, with the external layer of bone partially removed and the maxillary sinus exposed.
