CAMRT Radiography Practice Exam

Where is the coronoid process located?

1. Proximal ulna and mandible

2. Sternum and clavicle

3. Radius and tibia

4. Femur and fibula

The correct answer is: Proximal ulna and mandible

The coronoid process is a distinctly shaped bony structure found at two different locations in the body. It is located on the proximal ulna, which is part of the forearm, and on the mandible, which is the lower jawbone. In the case of the ulna, the coronoid process serves as an important landmark for articulating with the humerus at the elbow joint, contributing to the stability and movement of the elbow. On the mandible, the coronoid process provides an attachment point for the temporalis muscle, playing a significant role in jaw movement, especially in elevation during chewing. Understanding the anatomy and functionality of these processes is crucial for radiographers, as they frequently assess and interpret imaging of the upper limb and face. Recognizing the location and significance of the coronoid process aids in conducting thorough evaluations for potential fractures or other injuries in these areas.
