Answer: (D)

Verified step by step guidance

1. Understand the types of fibrous joints: Fibrous joints are connections between bones that are held together by dense connective tissue. The main types of fibrous joints are sutures, syndesmoses, and gomphoses.
2. Define each type of fibrous joint: Sutures are immovable joints found between the bones of the skull. Syndesmoses are slightly movable joints where bones are connected by a ligament, such as the distal connection between the tibia and fibula. Gomphoses are peg-in-socket fibrous joints, such as the connection between a tooth and its socket.
3. Identify the term 'synchondrosis': Synchondrosis is a type of cartilaginous joint where bones are joined by hyaline cartilage. An example is the epiphyseal plate in growing bones.
4. Compare the characteristics: Note that fibrous joints are characterized by the presence of fibrous connective tissue, while synchondroses involve cartilage.
5. Determine the correct answer: Since synchondrosis is a cartilaginous joint and not a fibrous joint, it is the correct answer to the question of which is not an example of a fibrous joint.
