EX3; Oral Mucosa Practical Images Flashcards
In addition to the labels, what do the red and purple arrows represent
- epithelium
- lamina propria
- submucosa
- bone/periosteum
red arrow = epithelium
purple arrow = connective tissue
Identify the labels and inidicate what type of epithelium these are found in
- superficial layer
- intermediate layer
- prickle cell layer
- basal cell layer
non-keratinized epithelium
- melanocyte
- langerhans cell
What kind of cells are indicated by the arrows
“clear” cells; like melanocytes, Langerhans, Merkel
What kind of cells are these
melanocytes
What cells are these
Langerhans
What are the differences between these two mucosas
- non-keratinized
- keratinized
identify the labels and indicate what type of epithelium this is
- keratinized layer
- granular layer
- prickle cell layer
- basal cell layer
keratinized epithelium
Which image depicts keratinized epithelium
the left
note; the dead keratinized layer
Which image depicts non-keratinized epithelium
the left
note; the superficial cell that contains its nucleus
What are these images depicting
membrane coating granules
What type of epithelium is this
keratinized
What kind of epithelium is this
keratinized
What kind of epithelium is this
keratinized
What kind of epithelium is the arrow pointing to
non-keratinized
What kind of epithelium is this
non-keratinized
What kind of epithelium is this
non-keratinized
What kind of epithelium is this
non-keratinized
What kind of epithelium are A, B, and C
A and B = keratinized
C = non-keratinized
What kind of epithelium (gingiva) is this
parakeratinized
What are the variations in these two images
A; incomplete keratinization
B; hyperkeratinization
What tissue is this
lamina propria
What so the black dots indicate
type 1 collagen
ther is more type 1 collagen in less flexible regions
What are these images depicting
epithelial/connective tissue interface
can see the rete pegs and the connective tissue papillae
What is this image depicting
long thin rete pegs and connective tissue papillae
What are the images on the left and right
left = submucosa
right = mucoperiosteum
What do the blue and purple dotted lines indicate
blue = lamina propria
purple = submucosa

What are the labels and what is this an image of
labial mucosa
- muscle
- salivary glands
- lamina propria

What do the green and yellow arrows indicate
green = alveolar (lining)
yellow = gingiva (masticatory)
- gingival margin
- sulcular epithelium
- gingival epithelium
- dentin
- connective tissue
- junctional epithelium
- enamel space
