Please help fill out the following illustration 

### Educational Content on Fetal Skull Sutures

**Text Explanation:**
The diagram illustrates the anatomy of a fetal skull, highlighting the locations of various fontanels and future sutures. It mentions the anterolateral fontanel located behind the eye orbit, between the anterior and anterolateral fontanels. A membranous line is visible at these joint areas, which indicates the future development of the coronal suture.

**Diagrams:**

#### Left Diagram:
- **Labels:**
  1. Anterior Fontanel
  2. Anterolateral Fontanel
  3. Future Coronal Suture
  4. Posterolateral Fontanel

This diagram displays a lateral view of the fetal skull. The anterior fontanel is shown at the top, highlighted in yellow, indicating a membranous gap that allows for brain growth and skull flexibility during birth. The anterolateral fontanel is positioned near the side, and the future coronal suture is illustrated as a line extending across the skull's top. The posterolateral fontanel, towards the base of the skull, is similarly highlighted.

#### Right Diagram:
- **Labels:**
  5. Future Sagittal Suture
  6. Future Squamosal Suture
  7. Posterior Fontanel

This diagram presents a superior view of the fetal skull. The future sagittal suture runs along the midline of the skull. The future squamosal suture, visible on the side, will develop laterally. The posterior fontanel, also highlighted in yellow, indicates a membranous area at the back of the skull.

**Assignments:**
- Students are tasked with labeling the structures in Figure 12.7.
- They should examine a fetal skull to identify all fontanels and future sutures.
- Completion of a Laboratory Report for the findings is required.
