The mandible grows primarily at which two locations?

  1. Condyles & posterior border of ramus

  2. Chin & condyles

  3. Posterior border of ramus & anterior border of ramus

  4. Alveolar ridge & chin

The correct answer is: Condyles & posterior border of ramus

The mandible is the lower jaw and is the largest and strongest bone in the face. It is essential for speaking, chewing and breathing. The mandible primarily grows at two locations, the condyles and the posterior border of the ramus. The chin and condyles are incorrect because this is only one of the locations where the mandible grows. The same goes for the posterior border of the ramus and anterior border of the ramus, as these options do not include both locations. The alveolar ridge, which is the arch in the upper and lower jaw that holds the teeth, is incorrect because it is not one of the primary locations where the mandible grows.
