Exam 23: Oral Mucous Membrane

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.

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

The attached gingiva is less movable than the adjacent alveolar mucosa because the attached gingiva is loosely attached to its underlying connective tissue.

Healthy gingiva is usually

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

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

Basement membrane appears as ridges and pegs projecting from connective tissue into its surface epithelium.

Stratified squamous epithelium is keratinized.

Which gingival structure is located closest to the alveolar mucosa?

Which lesion or condition contains thickened layers of stratum spinosum and stratum corneum?

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

In the maxillary arch,the lingual gingiva changes to alveolar mucosa,as it does in the mandibular arch.Palatal mucosa is thick and keratinized.

Each of the following is an indicator of gingival or periodontal disease EXCEPT one.Which one is the EXCEPTION?

Lack of stippling in the alveolar mucosa is due to epithelium that is not attached tightly to bone.This is initially caused by increased interdigitation between connective tissue and surface epithelium.

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

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.

The interdental papilla is made up of both free and attached gingiva.

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

Which term can be used to describe the epithelium that lines the sulcus (Select all that apply. )?

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