The coronoid process serves as an attachment site for which muscles?

• A. Temporalis
• B. Masseter
• C. Medial Pterygoid
• D. Lateral Pterygoid

Answer: (A)

The coronoid process is the insertion point for the temporalis muscle. The temporalis originates in the temporal fossa and its tendon runs downward to attach to the coronoid process of the mandible (near the anterior border of the ramus). This placement allows the temporalis to elevate the mandible and aid in jaw closure, with the posterior fibers also helping retract the mandible. The other muscles attach to different parts of the mandible: masseter to the lateral surface of the ramus and angle, medial pterygoid to the medial surface near the angle, and lateral pterygoid to the neck of the mandible and the articular disc. So the coronoid process specifically serves as the attachment for the temporalis.
