Female reproductive

Question 1

primordial follicle

Answer 1

• earliest stages of follicular devel

* single layer of squamous follicle cells with stretched out nucleus’s surround oocyte

Question 2

balbiani body

Answer 2

localized accumulation of golgi bodies, ER, centrioles, mitochondria

Question 3

primary follicle

Answer 3

• 1st growing stage of follicle
• CUBOID cells surrounding follicle
• zona pellucida - secreted pertinacious coat

Question 4

follicle cells become?

Answer 4

granulosa cells after rapid replication as primary follicle

Question 5

theca folliculi cells differentiate into two layers outside of granulosa cells

Answer 5

1) theca interna -highly vascularized cuboid STEROID producing secretory cells, fibroblasts and collagen
- -responds to LH by producing estrogen and androgen precursors
2) theca externa- outer layer of connective tissue; mainly smooth muscle cells and bundles of collagen fibers

Question 6

boundary betwen theca interna and externa is?

Answer 6

indistinct; but the basal lamina and theca folliculi cells is distint

Question 7

late primary follicle

Answer 7

• thick layer of granulosa cells, then basement membrane, then theca cells
• balbiani organelles disperse and multiply in cell
• have cortical granules

Question 8

cortical granule

Answer 8

where sperm gains entry! closest to zone pellucida

Question 9

oolema

Answer 9

oocyte plasma membrane

Question 10

secondary follicles

Answer 10

*characterized by antrum

Question 11

atrum

Answer 11

a bunch of hyaluronan (liquir folliculi) fluid filled spaces coalesce to form antrum

Question 12

cumulus oophorus

Answer 12

thickened area of stratum granulosum in secondary follicles

Question 13

corona radiate cells

Answer 13

cells incumulus oophorus that are in direct contact with oocyte and STAY IN CONTACT withreleased oocyte

Question 14

cell-exner bodies

Answer 14

hyaluronan and proteoglycan aggregates between granulosa cells

Question 15

mature or graafian follicles

Answer 15

spans entire thickness of ovarian cortex

*thecal layers more prominent

Question 16

corpus luteum cells

Answer 16

1) granulosa cells (80%) central=estrogen, progesterone and inhibin (small dark)
2) theca lutein cells= periphery; androgens and progesterone (larger,paler)

Question 17

corpus luteum becomes what if fertilization doesn’t occur?

Answer 17

corpus albicans

Question 18

uterine tube parts

Answer 18

1) infundibulum
2) ampulla- fertilization
3) isthmus
4) uterine part

Question 19

uterine tube layers

Answer 19

1) serosa or peritoneum- outer, mesothelium and CT
2) muscularis- inner thick and circular layer and outer thinner longitudinal layer
3) mucosa- thick folds projectin ginto lumen, most numerous in ampulla

Question 20

lumen of uterine tubes is lined by?

Answer 20

1) ciliated columar cells- numerous in infundibulum and ampulla
2) nonciliated columnar cells- secretory and produce fluid providing nutreients to ovum
* depending on hormonal respinse the SAME cell can become ciliated or not

Question 21

3 layers of uterus

Answer 21

1) endometrium- mucosallayer
2) myometrium- thick, continuous with muscle of uterine tube, smooth mucles extends into ligaments to connect uterus
3) perimetrium- out serous layer, loose CT, elastic tissue

Question 22

proliferation phase

Answer 22

estrogen; follicular maturation, 10 days

Question 23

secretory phase

Answer 23

progesterone secretion; corpus luteum activity (14 days), ENLARGED glands and lengthened arteries, glycogen rich

Question 24

menstrual phase

Answer 24

hormone production by ovary declines with degradation of corpus luteum, 3-5 days, desquamation/sloughing, blood flor ceases to basal layer (but not functional)

Question 25

mentrual cycle is ultimatly controlled by?

Answer 25

gonadotropins secreted by the par distalis of pituitary

Question 26

lining of lactiferous duct, lactiferous sinus, and rest of ducts

Answer 26

duct= stratified squamous sinus= two cuboidal cells rest of ducts= single layer of cuboidal
