Final answer:
The hollow bits of the bone in the mandible are known as alveolar sockets, which anchor the lower teeth.
Step-by-step explanation:
The hollow bits of the bone in the mandible show as alveolar sockets. In the anatomy of a tooth, the teeth are secured in these alveolar sockets of the mandible. Alveolar processes are the parts of the jaws where the sockets for the teeth are located. The alveolar process of the mandible serves to anchor the lower teeth. In contrast to a mandibular fossa, which is part of the temporomandibular joint, the alveolar sockets are specific depressions within the jawbone that house the teeth.These sockets are part of the alveolar processes of the mandible that hold the teeth in place. The dental sockets, or alveolar sockets, are lined with soft tissues called gingivae and held in place by the periodontal ligament.
