Q

the epithelial cells at the ____ of the injury will lose their desmosomal intercellular junctions and ___ to form a new epithelial surface layer beneath the clot

A

periphery

desmosomal

18
Q

turnover of ct proper in skin or oral mucosa occurs as a result of the production of____ and _____ by _____

A

fibers
intercellular substance
fibroblasts

19
Q

when injured, the ct proper in the skin or oral mucosa goes through stages of repair that are ____ to the events in the more superficial epithelium

A

related

20
Q

after a clot forms and a inflammatory response is triggered with WBC, ____ migrate to produce an immature ct deep to the clot and newly forming epithelial surface

A

fibroblasts

21
Q

the immature connective tissue is considered_____ and has few fibers and an increased number of blood vessels

A

granulation tissue

22
Q

appears as a redder, soft tissue that bleeds easily

A

granulation tissue

23
Q

may become abundant and can interfere with the repair process. surgical removal of excess granulation tissue may be necessary to allow for optimum repair. sometimes occurs after the extraction of teeth or with periodontal disease

A

granulation tissue

24
Q

later, during the repair process, this temporary granulation tissue is replaced by paler and firmer ______ in the area

A

scar tissue

25
Q

contains an increased number of fibers and fewer blood vessels

A

scar tissue

26
Q

what shows more scar tissue both clinically and microscopically after repair than does the oral mucosa

A

skin

27
Q

unlike skin and lips, the oral mucosa is ____ from changes due to ultraviolet radiation

A

protected

28
Q

it is sometimes_____ to distinguish oral mucosa changes caused by aging from changes caused by chronic disease

A

difficult

29
Q

in some regions of oral mucosa, there is a slight ____ of the epithelium with a concomitant flattening of the epithelial-connective tissue interface

A

thinning

30
Q

aging of oral mucosa:there is a reduction of ___ on the attached gingiva

A

stippling

31
Q

aging of oral mucosa: an increase in _____ in the labial and buccal mucosa

A

fordyce’s spots

32
Q

aging of oral mucosa: enlargement of ____ veins to form lingual varicosities on the ventral surface of tongue

A

lingual

33
Q

aging of oral mucosa: the _____ decrease in quantity, appear smaller, and are less active in older oral mucosa

A

fibroblasts

34
Q

aging of oral mucosa: the ____ has a slower collagen turnover time

A

entire lamina propria

35
Q

aging of oral mucosa: the ability of the oral mucosa to repair itself is____ and the length of the repair time is _____ just as turnover time

A

reduced

increased

36
Q

the number of lingual papillae, especially the ___ lingual papillae, and associated taste buds is also reduced and may be related to changes in taste perception

A

foliate

37
Q

changes in the salivary glands that result in less production of saliva

A

hyposalivation

38
Q

less production of saliva, which makes the oral mucosa drier and less protective

A

xerostomia

39
Q

less defined division between the ___ and dense layers of lamina propria with age

A

papillary

40
Q

in older oral mucosa, collagen fibers appear ____ and arranged into dense bundles resembling those found in tendons or ligaments

A

thickened

41
Q

elastic fibers in older oral mucosa, if present in lamina propria, appear ____ even though more of them are present; loss of resiliency found in aged oral mucosa

A

changed
