Which Structure is the MOST Vascular in Appearance

Question

Which structure is the MOST vascular in appearance?
A) Mucogingival junction
B) Alveolar mucosa
C) Labial frenum
D) Gingiva

Accepted Answer

The alveolar mucosa,a thin layer of loosely attached and movable tissue,covers a highly vascular area.The presence of blood vessels immediately under this relatively thin mucosa is responsible for the general reddish color.By contrast,the mucogingival junction that divides the attached gingiva from the alveolar mucosa appears more pink in color.The gingiva and labial frenum also appear pink in color.
