HOSA Dental Terminology Practice

Which anatomical structure is associated with the term "frenum"?

1. Tooth enamel

2. Tissue that controls the movement of the tongue and lips

3. The center of the tooth

4. A cavity in the gums

The correct answer is: Tissue that controls the movement of the tongue and lips

The term "frenum" refers to a fold of tissue that helps to control the movement of the tongue and lips, thus playing a significant role in oral functions such as speech and swallowing. There are specific frenula in the mouth, including the labial frenulum, which connects the inner lip to the gums, and the lingual frenulum, which extends from the floor of the mouth to the underside of the tongue. This tissue allows for a certain degree of mobility and stabilization of these oral structures, making it crucial for proper oral function and development. Understanding the role of frenula is essential in dentistry, particularly when assessing issues related to tongue ties and other conditions that might affect oral health and communication.
