Types of Suture Joints & Their Examples

Sutures are fibrous type of joint  found between skull bones. They are classified based on the shape of articulating edges.

1. Serrate Suture (Strongest, Interlocking Edges)

• Example:
  • Sagittal suture (between two parietal bones)
  • 
    
  • Coronal suture (between frontal and parietal bones)

2. Denticulate Suture (Tooth-Like Interlocking)

• Example:
  • Lambdoid suture (between occipital and parietal bones)

3. Squamous Suture (Overlapping Edges)

• Example:
  • Squamous suture (between temporal and parietal bones)

4. Plane Suture (Flat, Smooth Edges)

• Example:
  • Internasal suture (between two nasal bones)
  • Intermaxillary suture (between two maxillae)
  • Interpalatine suture (between two palatine bones)

5. Schindylesis (Wedge and Groove)

• Example:
  • Spheno-vomerine joint (between sphenoid and vomer bones)
