Exam 23: Oral Mucous Membrane

Lining mucosa that extends beyond the area of the tonsils is called the oral mucous membrane. Lining mucosa is composed of stratified squamous epithelium.

Which of the following accurately describe the gingival sulcus (select all that apply)?

Each of the following structures is covered in masticatory mucosa EXCEPT one. Which one is the EXCEPTION?

Epithelial cells are generally pink in color because they reflect the surrounding gingival tissues.

Masticatory mucosa is able to withstand trauma or compression during mastication because its surface lacks keratin, an especially vulnerable surface covering.

The length of connective tissue ridges and pegs that project into surface epithelium determines how movable the epithelium is. The connective tissue is attached to underlying bone in all areas.

In attached gingiva, the junction of the epithelium and the connective tissue are tightly bound because ridges and pegs of connective tissue project up into the epithelium.

Which gingival structure is located closest to the alveolar mucosa?

Each of the following accurately describes submucosa EXCEPT one. Which one is the EXCEPTION?

During passive eruption the attachment epithelium moves from the crown of the tooth in an apical direction. As the tooth breaks through the oral cavity the attachment epithelium is formed from the basement membrane.

The col is the part of the interdental papilla that

In which stage of passive eruption is the attached epithelium located on the cementum apical to the CEJ?

The mucosa that responds to constant trauma from chewing by becoming thick and keratinized in a line corresponding to the occlusal surfaces of the teeth is the

A mucocele is a typical sebaceous gland found in the buccal mucosa.

Sleep apnea is caused by inadequate connective tissue of the hard palate. This condition cause patients to experience deep sleep, but for very limited periods of time.

Healthy gingiva is usually

Which of the following structures is covered with lining mucosa (select all that apply)?

Healthy oral mucosa often appears white because underlying nutritive collagen fibers reflect through the thin mucosal epithelium.

As keratinization increases, which of the following tend to increase (select all that apply)?

The redness of the oral mucosa is due to pigments in hemoglobin.
