For 3rd year dental students

ORAL MUCOUS MEMBRANE

(ORAL MUCOSA)


Non-Keratinization in oral epithelium in human gingiva..

Superficial layer

Intermediate layer

Basal layer

Prickle cell layer


Parakeratinization of oral epithelium..


Musticatory mucosa-Orthokeratinization of oral epithelium..

Keratinized layer (stratum corneum)

Basal cell layer(startum basale)

Stratum germinativum

Granular cell layer (stratum granulosum)

Prickle cell layer(stratum spinosum)


The intercellular bridges or prikles are desmosomes..


Basal cell layer of oral epithelium..

Silver stain

Clear haloes around nucli

H&E

PAS stain


Sebaceous glands (Fordyce spots) in lamina propria of human buccal mucosa


STIPPLING ON THE EPITHELIUM..

Sites of stippling

Surface epithelium(keratinized layer)

Laminapropria


Circumvallate papilla


FILLIFORM PAPILLAE

  • Orthokeratinized surface epithelium..
