where are langerhans cells found

A

spinous layer

28
Q

leukocytes

A

found in epithelium

lymphocytes and neutrofils

29
Q

Langerhans cell histiocytosis

A

rare cancer
proliferation of langerhams cells
- bone has largely gone, teeth essentially floating

30
Q

types of oral muscoa

A

masticatory
lining
gustatory
specilaised

31
Q

masticatory muscosa

A

areas of high abration

e.g. hard palate and gingica

32
Q

lining muscos

A

areas nit subject to high abration i.e. floor of mouth./vertral tongue

33
Q

gustatory lining muscsa

A

specliased for resistance by papillae and cast buds e.g. dorsal tongue

34
Q

specialised mucsoa

A

does not fit into other catagoies

i.e. vermillion border, junctional epithelium

35
Q

what is the muscle liken the palatal vault

A

pale

no submuscoa so bound to underlying bone

36
Q

where can you get minor glands which can become tumourised

A

lateral palate

37
Q

histology of masticatory epithelium

A

parakeratinised stratifised squamous eptuehlium
deep rate ridges o allow anchoring with CT
dense lamina propria

38
Q

where is the mucogingical junction

A

transition masticatory to the lining mucosa

39
Q

free gingival groove

A

junction between attached and free gingivae

40
Q

what is the marginal gingiva also known as

A

free ginigva

41
Q

what is attached gingiva attached to

A

attached to bone

42
Q

junctional epithelium

A

2 basal lamina/basment membrane
- once on deep and other on superficial side
adjacent to enamel or cementum
wide intracellular spaces

43
Q

what is at junctional epithelim

A

crevicular fluid

44
Q

crevicular fluid

A

may contain leukocytes
contains secretory IgA
clears out and neutralises bacteria
Serum exudate through junctional epithelial cells

45
Q

lining on the buccal mucosa

A

lining mucosa
stratified squamous
non keratinesed
- may be along occlusal plane due to biting or grinding
dense lamina proproa
sub mucosa - loose and minor salivary glands
may contain sebaceous glands on occlusal plane

46
Q

soft palate oral side

A

lining muscosa no keratinsed
minor mucous salivary glands
submucosa blends with underling muscles

47
Q

vermillion border

A

where skin meets the lip
transitional zone between hairy skin and lining oral mucosa
no appendages
thin lamina propria bound to underlain muscle

48
