A
Periodontal ligament
B

C
Hyoid bone
D
Styloid process
Verified step by step guidance1
Understand the definition of a gomphosis joint: A gomphosis is a type of fibrous joint where a conical process fits into a socket, such as the connection between teeth and their sockets in the jawbone.
Identify the anatomical structures involved in a gomphosis joint: The gomphosis joint in the head and neck region specifically refers to the connection between the teeth and the alveolar sockets of the maxilla or mandible.
Recognize the role of the periodontal ligament: The periodontal ligament is a specialized connective tissue that anchors the tooth to the alveolar bone, forming the gomphosis joint.
Evaluate the other options: The sphenoid sinus, hyoid bone, and styloid process are not involved in forming a gomphosis joint. These structures serve different functions in the head and neck region.
Conclude that the correct structure directly involved in forming a gomphosis joint is the periodontal ligament, as it provides the fibrous connection between the tooth and its socket.
