Question

Collectively, the roots, the dental alveoli, and the periodontal ligaments that bind the roots to the alveolar processes form a ______ joint.

Answer 1

The roots, dental alveoli, and periodontal ligaments that bind the teeth to the jaws form a gomphosis joint, which is a stable, immobile fibrous joint also known as a peg-and-socket joint.

Step-by-step explanation:

Collectively, the roots, the dental alveoli, and the periodontal ligaments that bind the roots to the alveolar processes form a gomphosis joint. A gomphosis, recognized as a peg-and-socket type of joint, is a fibrous connection between the tooth root and its bony socket in the upper or lower jaw. It is characterized by the presence of periodontal ligaments which consist of numerous short bands of dense connective tissue. Functionally, gomphosis joints are classified as synarthroses because they offer stability and virtually no mobility, with the teeth firmly anchored into the alveolar processes of the maxilla and mandible, providing structure and support for oral activities.
