general- oral and genital mucosa Flashcards
type of epithelium in oral mucosa
stratified squamous epithelium aka oral epithelium
calsfication of oral mucosal epithelieum
3
masticatory - keratinized - hard palate and dorsal tongue lining - buccal, labial, alveolar specialized - tastebuds
structure of oral mucosa
2 layers
- surface stratified squamous epithelieum
- lamina propia
structure of keratinized oral mucosa
1.Stratum basale (basal layer)2.Stratum spinosum (prickle layer)3.Stratum granulosum (granular layer)4.Stratum corneum (keratinized layer
(same as skin)
plus lamina propria
structure of non keratinized oral mucosa
stratum basale and spinosum are the same
granulosum and corneum replaced by imdt and superficial layers w/o keratin
what is keratinization
differentions of skin cells from stratum basale to stratum corneum as they migrate outwards and accumulate keratin
what is hyperkeratnization
transformation of non K
into K epithelium in response to friction/ trauma
what is the linea alba
line of white hyperkeratinization on the buccal surfaces whwere the madibullar and maxillary teeth occlude
what causes excess linea alba formation
bruxism (grinding of teeth)
what is the lamina propria
fibrous connective tissue consisting of collagen type 1 and 3 made by fibroblasts
layers of lamina propria
1) PAPILLARY LAYER
2) DENSE LAYER
a capillary plexus between for nutrition
what is a fordyce spot
small yellow bumps in non K epithelium d/2 misplaced sebaceous glands in submucosa
what epithelium covers the skin
stratified squamous
3 erectile tissues of the penis
2 corpora cavernosum either side of
corpopra spongiosum that the urethrea passes through
what lines the prostatic penis
transitional epithelium
