Which of the following sutures connects the greatest number of bones in the human skull?

• A. Coronal suture
• B. Squamous suture
• C. Sagittal suture
• D. Lambdoid suture

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the concept of sutures in the human skull. Sutures are immovable joints that connect the bones of the skull. They are made of dense fibrous connective tissue and play a crucial role in protecting the brain and providing structural integrity to the skull.
2. Step 2: Review the names and locations of the major sutures in the human skull. The coronal suture connects the frontal bone to the parietal bones. The sagittal suture connects the two parietal bones. The lambdoid suture connects the parietal bones to the occipital bone. The squamous suture connects the parietal bone to the temporal bone.
3. Step 3: Analyze the number of bones connected by each suture. For example, the coronal suture connects two bones (frontal and parietal), the sagittal suture connects two bones (parietal and parietal), the lambdoid suture connects three bones (parietal and occipital), and the squamous suture connects multiple bones (parietal, temporal, and parts of the sphenoid).
4. Step 4: Compare the sutures based on the number of bones they connect. The squamous suture connects the greatest number of bones, as it involves the parietal, temporal, and parts of the sphenoid bone.
5. Step 5: Conclude that the squamous suture is the correct answer because it connects the greatest number of bones in the human skull compared to the other sutures listed.
