What are the two oblique elevations found laterally from the lingual frenum?

The two oblique elevations located laterally from the lingual frenum are indeed referred to as the sublingual folds, also known as the plica sublingualis. These folds are part of the sublingual gland structure, which is situated beneath the tongue and plays an important role in salivary secretion. The sublingual folds help to support the tissue of the mouth and provide pathways for the ducts of the sublingual glands to release saliva into the oral cavity.

Understanding the anatomical features of the mouth, including the sublingual folds, is essential for dental hygienists and other dental professionals as they assess for health conditions and educate patients about oral anatomy. The clear definition of these folds highlights their significance in relation to saliva production and the overall function of the oral cavity, underscoring their essential role in oral health.
