HISTOLOGY

Question 1

what is the outer layer of epithelium of ovarian cortex (outer)

Answer 1

cuboidal epithelium (germinal epithelium)

Question 2

what is internal to cuboidal epithelium in the ovarian cortex (outer)

Answer 2

tunica albuginea

Question 3

what is in the medulla (inner) of the ovaries

Answer 3

arteries, veins, lymphatics, loose connective tissue

Question 4

folliculogenesis definition

Answer 4

growth of a follicle

Question 5

what is a follicle made of

Answer 5

oocyte and support cells (pregranulosa cells)

Question 6

by what movement does oocytes travel down the fallopian tubes
which type of epithelium allows this to happen

Answer 6

peristalsis

ciliated epithelium (think hairy)

Question 7

which layer of the uterus contains glands

why are they here

Answer 7

endometrium (the layer that is shed)

to secrete mucosa into uterus

Question 8

which part of the endometrium is the part that sheds and grows each month

which part remains

Answer 8

stratum functionalis sheds (its the functional bit)

stratum basalis stays (= its the base)

Question 9

what happens to arterioles to allow the shedding of stratum functionalis

Answer 9

they become constricted = ischaemia of tissue = breaks down

Question 10

what is the myometrium made of

Answer 10

smooth muscle, cartilage, elastic

Question 11

what is the perimetrium made of

Answer 11

loose connective tissue, mesothelium (on outside)

Question 12

what are the 2 histologically defined areas of the cervix

what is between them

Answer 12

ectocervix
endocervix

separated by the squamocoloumnar junction (transition zone TZ)

Question 13

where is the ectocervix

what type of cells are there

Answer 13

closer to vagina

stratified squamous epithelium

Question 14

where is the endocervix

what type of cells are there

Answer 14

closer to uterus (en = further IN)

simple columnar epithelium

Question 15

in the cervix, are the cervical glands in the ectocervix or the endocervix

Answer 15

endocervix (next to uterus - uterus also has glands)

Question 16

over time what is a normal metaplasia in the cervix
why

what does this cause

Answer 16

in the endocervix (closer to uterus)
simple columnar epithelium changes to squamous epithelium

bc of exposure to acid from vagina

causes a change in the transition zone

Question 17

where is the transitional zone (squamocolumnar junction) of the cervix

Answer 17

between the endocervix (simple columnar epithelium) and ectocervix (stratified squamous epithelium)

Question 18

clinical significance of transition zone (squamocolumnar epithelium) of cervix

why

Answer 18

most susceptible to dysplasia

bc the transition zone changes over time anyway

Question 19

are there glands in the vaginal epithelium

Answer 19

no - lubrication only comes from cervical glands in endocervix

Question 20

type of epithelium in vagina

Answer 20

non keratinized squamous epithelium (like inside of cheek)

Question 21

differencesbetween labia major and labia minor (2)

Answer 21

minor - no hair follicles, non keratinsed squamous epithelium (major is keratinized)

Question 22

what type of cells produce IgA, hence there are lots of in the breast

Answer 22

plasma cells

Question 23

in the breast, what are the acini/glands lined with

Answer 23

secretory epithelium (columnar or cuboidal)

Question 24

in the breast what are the ducts lined with (2)

Answer 24

stratified columnar epithelium at the start

thin stratified squamous epithelium near the nipple

Question 25

what type of epithelium is in the nipple

Answer 25

highly pigmented keratinized stratified squamous epithelium

Question 26

in the breast, where do sebaceous glands exit the skin (usually via hair follicles)

they produce sebum

Answer 26

via the nipple
