Evaluation, diagnosis, and treatment of gingival and periodontal conditions require a sound understanding of the structure of the gingival unit and periodontal attachment apparatus. Match the gingival structure with its corresponding description.

Premises
Melanin
Free gingiva
Attached gingiva
Stratified squamous epithelium
Gingival papilla
Dense collagen fibers
Alveolar mucosa
Responses
Surface covering of attached gingiva
Extends from free gingival margin to base of gingival sulcus
Extends from base of gingival sulcus to mucogingival junction
Free gingiva located in triangular interdental spaces
Located apical to the mucogingival junction
Composition of underlying mucosa of gingiva
Responsible for darker-colored gingiva
