The structure indicated is the mandibular notch.
The ramus of the mandible
forms the lateral portion of the mandible. It has two processes:
- Coronoid process
- Condyloid process
These processes extend superiorly from the ramus of the mandible. The coronoid process
is located anteriorly, and the condyloid process
is located posteriorly. In between these two processes is a concave notch, known as the mandibular notch. Passing through this notch are the following structures:
- Masseteric nerve
- Masseteric artery
- Masseteric vein
