Which of the following joints is categorized as a symphysis?

• A. Gomphosis
• B. Pubic symphysis
• C. Shoulder joint
• D. Suture of the skull

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the definition of a symphysis joint. A symphysis is a type of cartilaginous joint where bones are joined by fibrocartilage, allowing limited movement. Examples include the pubic symphysis and intervertebral discs.
2. Step 2: Review the characteristics of the other options provided in the question. For example, a gomphosis is a fibrous joint that anchors teeth to their sockets, a suture is a fibrous joint found in the skull, and the shoulder joint is a synovial joint that allows free movement.
3. Step 3: Compare the structural and functional properties of each joint type to the definition of a symphysis. Only the pubic symphysis fits the criteria of being a cartilaginous joint joined by fibrocartilage.
4. Step 4: Recall anatomical examples of symphysis joints in the human body, such as the pubic symphysis and intervertebral discs, to confirm the correct answer.
5. Step 5: Conclude that the pubic symphysis is the correct answer based on its structural classification as a symphysis joint.
