The Transverse Ridge is formed by what?

1. Movement of teeth

2. Union of two triangular ridges

3. Development of tooth enamel

4. Separation of tooth roots

The correct answer is: Union of two triangular ridges

The Transverse Ridge is formed by the union of two triangular ridges, which are raised areas on the occlusal surfaces of posterior teeth. These triangular ridges extend from the cusp tips toward the central part of the tooth and converge to create a ridge that runs transversely across the tooth. This feature is significant in dental anatomy because the transverse ridge plays a crucial role in the function of the tooth during mastication, as it aids in the grinding and crushing of food. Understanding the structure and formation of the Transverse Ridge can help dental professionals assess tooth wear, occlusal relationships, and overall dental health. The other options do not accurately describe the formation of the Transverse Ridge, as they pertain to different aspects of dental development and anatomy.
