mandible landmark
- body (corpus) - main part of bone; forms chin
- mental symphysis - where two halves fuse together
- mental protuberance - formed at midline
- mental spine (tiny holes) - on inner surface; point of attachment for muscle
- mylohyoib line - on inner surface; muscle attachments
- ramus - posterior projection upward
- angle of the mandible - where posterior and inferior margins of ramus meet
- coronoid process - projection from anterior part of ramus; temporal muscles inserts here
- condylar process - articulates with skull allowing rotation of mandible
