Which muscle is NOT attached to the ramus of the mandible?

  1. Medial pterygoid (medial surface of ramus/angle)
  2. Masseter (lateral surface of ramus)
  3. Lateral pterygoid (attaches to the condylar neck and pterygoid fovea — NOT the ramus body)
  4. Temporalis (inserts on coronoid process, part of ramus)
Show answer and explanation

Correct answer: C. Lateral pterygoid (attaches to the condylar neck and pterygoid fovea — NOT the ramus body)

  • A. Medial pterygoid attaches to the MEDIAL SURFACE of the ramus and angle — on the ramus.
  • B. Masseter attaches to the LATERAL SURFACE of the ramus (from the zygomatic arch above to the lateral ramus/angle below) — on the ramus.
  • C. Correct. The LATERAL PTERYGOID does NOT attach to the ramus proper — it inserts into the PTERYGOID FOVEA on the anteromedial aspect of the condylar neck (and into the articular disc). The ramus body itself is not the attachment site.
  • D. Temporalis inserts on the coronoid process AND anterior border of the ramus — on the ramus.
