A
- Normal anatomy informs pathology
- Microscopic changes in cells and tissues are translated into clinical disease
- Neoplasms originate from cellular components of tissues

Q
Vulva and Vagina
- L Majora skin with … follicles and … glands
- L minora and vagina - Mucosa with … … epithelium
A
- L Majora skin w hair follicles and sweat glands
- L minora and vagina Mucosa with stratified squamous epithelium

Q
Vagina at puberty
- … secreted by the ovary stimulates maturation of … epithelial cells
- Glycogen is formed within … … epithelial cells
- Glycogen in cells shed from the surface is a substrate for vaginal anaerobic organisms (dominated by …)
- … produce lactic acid keeping vaginal pH below …
A
- Oestrogen secreted by the ovary stimulates maturation of squamous epithelial cells
- Glycogen is formed within mature squamous epithelial cells
- Glycogen in cells shed from the surface is a substrate for vaginal anaerobic organisms (dominated by lactobacilli)
- Lactobacilli produce lactic acid keeping vaginal pH below 4.5

A
- Covered by stratified squamous epithelium
7
Q
Endocervix
- Single layer of tall, … producing … cells
A
- Single layer of tall, mucin producing columnar cells
8
Q
The endocervix has a deceptively large surface area
- … epithelium lines tiny blind ending channels (‘…’)
- These radiate out from the endocervical canal into the surrounding …
A
- Columnar epithelium lines tiny blind ending channels (‘clefts’)
- These radiate out from the endocervical canal into the surrounding stroma
9
Q
Cervix
- __The ectocervix is covered by … … epithelium
- The endocervix is lined by … epithelium
- The junction between the two is called the ‘…-… junction
A
- The ectocervix is covered by stratified squamous epithelium
- The endocervix is lined by columnar epithelium
- The junction between the two is called the ‘squamo-columnar junction
10
Q
Formation of the transformation zone
- During puberty the cervix changes …
- The … of the cervix grow
- The … end of the endocervix opens
- Endocervical … becomes exposed to the vaginal environment
A
- During puberty the cervix changes shape
- The lips of the cervix grow
- The distal end of the endocervix opens
- Endocervical mucosa becomes exposed to the vaginal environment

A
- The distal endocervical columnar epithelium is exposed to the acidic vaginal environment
- It is not suited to this, so undergoes an adaptive change called metaplasia
- Reserve cells in this area proliferate and mature to form squamous epithelium: This process is called squamous metaplasia
13
Q
Metaplasia =
A
a transformation of cell type from one kind of mature differentiated cell type to another kind of mature differentiated cell type

Q
Squamous Metaplasia - Cervix
- At first, the metaplastic squamous epithelium is … and … (lots of … & maturation is incomplete)
- With time, the metaplastic epithelium comes to be as strong and well formed as that on the …
A
- At first, the metaplastic squamous epithelium is thin and delicate (lots of proliferation & maturation is incomplete)
- With time, the metaplastic epithelium comes to be as strong and well formed as that on the ectocervix
