Pathology Of The Reproductive Tract Flashcards
What type of epithelium in labia minors and majora?
Stratified squamous
What does oestrogen do?
Stimulates maturation of squamous epithelial cells
Where is glycogen formed?
Squamous epithelial cells
Which vaginal anaerobic organisms are present?
Lactobacillus
What do lactobacillus do?
Produce lactic acid keeping vaginal pH below 4.5, glycogen formed by squamous epithelial cells is a substrate
White areas in picture are?
Where glycogen is being processed
Where are the blood vessels?
Within the stroma, none past bm in epithelium
Endocervix cells?
Single layer of tall mucin producing columnar cells, oval nuclei, with clefts protruding into stroma
How does cervix change in puberty?
Lips of cervix grow,
Distal end of endocervix opens , endocervical mucosa becomes exposed to acidic vaginal environment and then undergoes metaplasia
Disease, cancer starts where?
Transformation zone
What happens at distal endocervical columnar epithelium?
Squamous metaplasia by progenitor cells (reserve cells)
Metaplasia?
Transformation of cell type from one kind of mature differentiated cells type to another kind of mature differentiated cell type
Pathological metaplasia?
Barrett’s oesophagus
Metaplasia stages?
Begins thin and delicate (proliferation and incomplete maturation)
Then stronger and well formed such as ectocervix
What is myometrium made of?
Bundles of smooth muscle, vasculature and nerves
