Both the attached gingiva and buccal mucosa are mainly pinkish in color and not reddish due to the:

Select the correct answer(s).

(0/0)

Explanation

The nonkeratinized stratified squamous epithelium of the labial mucosa and buccal mucosa is extremely thick and overlies and obscures a lamina propria with an extensive vascular supply, giving the overall mucosa an opaque and pinkish appearance. The attac

The basal layer of oral mucosa in the oral cavity generally has:

Select the correct answer(s).

(0/0)

Explanation

The basal layer for both nonkeratinized and keratinized stratified squamous epithelium is a single layer of cuboidal epithelial cells overlying the basement membrane, which, in turn, is situated superior to the lamina propria

In the oral cavity, masticatory mucosa always contains a(n):

Select the correct answer(s).

(0/0)

Explanation

Histologically, masticatory mucosa is associated with orthokeratinized stratified squamous epithelium as well as parakeratinized stratified squamous epithelium. Superficial to the basal layer is the prickle layer for both types of keratinization.

When viewing the oral mucosa of the floor of the mouth through a microscope, which of the following can be noted?

Select the correct answer(s).

(0/0)

Explanation

The floor of the mouth has an extremely thin, nonkeratinized stratified squamous epithelium overlying, but not obscuring, a lamina propria with an extensive vascular supply. The connective tissue papillae of the lamina propria are broad in the floor of th

Which of the following areas of the oral cavity is categorized as a lining mucosa?

Select the correct answer(s).

(0/0)

Explanation

Lining mucosa includes the buccal mucosa, labial mucosa, and alveolar mucosa, as well as the mucosa lining the ventral surface of the tongue, floor of the mouth, and soft palate. Histologically, lining mucosa is a type that is associated with nonkeratiniz

Which of the following statements concerning pigmentation in the oral cavity is correct?

Select the correct answer(s).

(0/0)

Explanation

Melanin is a pigment formed by melanocytes, which are epidermal cells derived from the neural crest cells. Because melanocytes are evenly distributed throughout the oral mucosa, clinical levels of pigmentation are based on the degree of melanin-producing

What type of tissue makes up the bulk of the lamina propria of the oral mucosa?

Select the correct answer(s).

(0/0)

Explanation

The entire oral cavity has an epithelial covering with connective tissue making up the bulk of lamina propria

In a young adult, the buccal mucosa may contain Fordyce spots, which refer to:

Select the correct answer(s).

(0/0)

Explanation

A variable number of Fordyce spots are scattered throughout the tissue. These are a normal variant, visible as small, yellowish bumps on the surface of the mucosa. They correspond to deposits of sebum from misplaced sebaceous glands in the submucosa.

none

The attached gingiva of the oral cavity consists of which type of oral mucosa?

Select the correct answer(s).

(0/0)

Explanation

The oral mucosa of the attached gingiva that covers the alveolar process of the dental arches is classified as a masticatory mucosa. Alveolar mucosa is a type of lining mucosa.

none

Melanin pigment for the oral cavity is synthesized in which of the following cells?

Select the correct answer(s).

(0/0)

Explanation

The melanocytes have small cytoplasmic granules as inclusions called melanosomes, which store the melanin pigment that they have formed. They inject these granules into the neighboring, newly formed epithelial cells of the basal layer.

none

The mucogingival junction is absent from which of the following oral surfaces?

Select the correct answer(s).

(0/0)

Explanation

There are three areas where the anatomic feature of the mucogingival junction can be noted: on the facial of the maxillary arch and on both the facial and lingual of the mandibular arch but not on the palate.

none

Keratohyalin granules are located in which of the following epithelial layers in the oral cavity?

Select the correct answer(s).

(0/0)

Explanation

Superficial to the prickle layer is the granular layer, or stratum granulosum. The epithelial cells in this layer are flat and stacked in a layer three to five cells thick. In the cytoplasm, each of the cells has a nucleus with prominent keratohyaline gra

Which of the following layers make up the bulk of nonkeratinized epithelium in the oral cavity?

Select the correct answer(s).

(0/0)

Explanation

The intermediate layer makes up the bulk of nonkeratinized stratified squamous epithelium. Each area of lining mucosa has at least three layers within the epithelium: basal, intermediate, and superficial. The prickle cell layer is found instead in both or

Which of the following layers of nonkeratinized stratified squamous epithelium produces the basal lamina of the basement membrane within the oral mucosa?

Select the correct answer(s).

(0/0)

Explanation

The basal layer produces the basal lamina of the basement membrane. Each area of lining mucosa has at least three layers within the epithelium: basal, intermediate, and superficial. The prickle cell layer is found instead in both orthokeratinized stratifi

Which is the most superficial layer of the lamina propria of oral mucosa?

Select the correct answer(s).

(0/0)

Explanation

The lamina propria, like all forms of connective tissue proper, has two layers: papillary and dense. The lamina propria, like all forms of connective tissue proper, has two layers: papillary and dense. Between the papillary layer and the deeper layers of
