Question

multiple choice question

the intermaxillary suture in the roof of the mouth is an example of what type of suture?

plane
serrate
lap

Explanation:

Identify suture types

Using the Sutures and Skull Sutures knowledge points, sutures are fibrous joints classified by their articulating edge shapes: serrate, lap (squamous), and plane (butt).

Analyze intermaxillary suture

The intermaxillary suture joins the two maxillae at the hard palate. The bone edges are straight, non-overlapping, and meet end-to-end.

Match with definitions

Using the Serrate Suture and Lap Suture knowledge points:

• Serrate sutures have interlocking, wavy edges.
• Lap sutures have overlapping, beveled edges.
• Plane sutures have straight, non-overlapping borders.

Thus, the intermaxillary suture is a plane suture.

Answer:

• (A) Plane (Correct answer)
• (B) Serrate
• (C) Lap
