Verified step by step guidance

Step 1: Understand the definition of a fibrous joint. Fibrous joints are connections between bones where the bones are held together by dense connective tissue, allowing little to no movement.
Step 2: Learn about the specific types of fibrous joints. These include sutures (found in the skull), syndesmoses (bones connected by ligaments), and gomphoses (peg-in-socket joints).
Step 3: Focus on the term 'peg-in-socket.' This describes a joint where one bone fits into a socket-like structure of another bone, such as the connection between teeth and their sockets in the jawbone.
Step 4: Match the description 'peg-in-socket' to the correct type of fibrous joint. Gomphosis is the term used for this type of joint, specifically referring to the tooth and its alveolar socket.
Step 5: Review the other options provided (syndesmosis, suture, synchondrosis) to ensure they do not fit the 'peg-in-socket' description. Syndesmosis involves ligaments, suture involves interlocking bones in the skull, and synchondrosis is a cartilaginous joint, not fibrous.
