Which structure is NOT involved in the description of the frenulum of the lip?

The frenulum of the lip, specifically the labial frenulum, is a thin fold of tissue that connects the inner surface of the lip to the alveolar mucosa, the underlying gum tissue. It helps to stabilize the position of the lip and allows for movement during speech and eating.

The alveolar mucosa plays a significant role in the structure of the frenulum, as it is the area where the frenulum attaches, enabling the lip to have proper function and mobility. The description of the frenulum often includes its position through the middle of the lip, as it typically runs centrally from the lip to the gums.

Additionally, when discussing the frenulum, the inner surface of the lip is also considered, as this is where the frenulum originates. In contrast, the gums refer specifically to the tissue surrounding the teeth and do not participate in describing the frenulum's anatomy or function. Thus, while the frenulum is connected to the alveolar mucosa, the gums themselves do not have a direct role in the description of the frenulum of the lip.
