Question

Quizplus · Accepted Answer

The joint between the teeth and the mandibular alveolus is a gomphosis joint. This is a specialized type of fibrous joint where a conical structure is inserted into a socket and held in place by ligaments. In this case, the tooth (conical structure) is inserted into the socket of the mandibular alveolus and held in place by periodontal ligaments. Sutures (A) are fibrous joints found only in the skull, where the bones are tightly interlocked. Syndesmosis (B) are fibrous joints where bones are connected by a ligament, and can allow for slight movement. Synostosis (D) happens when two bones fuse together, and symphysis (E) are cartilaginous joints that provide slight movement as they are connected by a pad of fibrocartilage.
