Step 1: Break Down the Problem

We need to identify the specific suture formed between the parietal bones and the frontal bone.

Step 2: Relevant Concepts

• Sutures are fibrous joints that connect the bones of the skull.
• The frontal bone is at the front of the skull, while the parietal bones are located behind it.

Step 3: Analysis and Detail

Among the given options:

1. Fontanel: This refers to the soft spots between an infant's skull bones, not a suture.
2. Lambdoidal: This suture is located between the parietal bones and the occipital bone, not with the frontal bone.
3. Squamous: This suture is found between the parietal and temporal bones.
4. Coronal: This suture connects the frontal bone to the parietal bones.

Step 4: Verify and Summarize

The Coronal suture is the one that connects the frontal bone to the parietal bones, making it the correct answer.

Final Answer

The parietal bones form the Coronal suture with the frontal bone.
