Question

multiple choice question

which describes the edges of a serrate suture?

interlocking
overlapping
non-overlapping

Explanation:

Define suture types

Using the Skull Sutures and Sutures knowledge points
Sutures are fibrous joints found only in the skull. Based on the structure of their margins, they are classified into three main types:

• Serrate sutures: Have interlocking, wavy lines resembling the teeth of a saw.
• Lap (squamous) sutures: Have overlapping, beveled edges.
• Plane (butt) sutures: Have straight, non-overlapping edges.

Analyze serrate suture edges

Using the Sutures knowledge point
The term "serrate" comes from the Latin serratus, meaning "toothed like a saw." The interlocking nature of these wavy margins provides a highly secure connection between adjacent cranial bones, such as the sagittal suture between the parietal bones. Therefore, the edges of a serrate suture are described as interlocking.

Answer:

• Interlocking (Correct answer)
• Overlapping
• Non-overlapping
