Histology Female Repro

Question 1

What are the six external organs of the female repro system?

Answer 1

mons pubis, labia majora, labia minora, clitoris, external urethral orifice, vaginal orifice

Question 2

What are the two endocrine products of the ovaries

Answer 2

estrogen, progesterone

Question 3

What is the role of the estrogen produced in the ovary?

Answer 3

it promotes the growth and maturation of internal and external sex organs; promotes cyclic changes in uterine mucosa; development of secondary female sex characteristics such as breast development

Question 4

What is the role of progesterone produced in the ovary?

Answer 4

progesterone prepares the internal sex organs (primarily the uterus) for pregnancy by promoting changes in endometrium; preparing mammary glands for function

Question 5

What is the exocrine product of the ovary?

Answer 5

oocyte

Question 6

Ovarian follicles are found within the _____ of the ovaries

Answer 6

cortex

Question 7

An ovarian follicle is composed of what?

Answer 7

an oocyte surrounded by one or more layers of epithelial cells

Question 8

What are the three basic types of ovarian follicles?

Answer 8

1) primordial, 2) growing (further divided into primary and secondary), 3) mature (Graafian)

Question 9

How many ovarian follicles are present in the fetus?

Answer 9

5 million

Question 10

How many ovarian follicles are present in a female at birth?

Answer 10

600,000 to 800,000

Question 11

How many ovarian follicles are present at the beginning of puberty?

Answer 11

300,000

Question 12

How many ovarian follicles are ovulated?

Answer 12

400

Question 13

Theca folliculi (follicular theca) is the sheath of _____ _____ cells that develop from what?

Answer 13

connective tissue, stromal cells surrounding the developing follicle

Question 14

Theca folliculi are found where?

Answer 14

just external to the basal lamina

Question 15

The theca folliculi differentiates into two parts:

Answer 15

theca interna (cuboidal secretory cells, in response to LH, synthesize and secrete androgens, endocrine function), theca externa (fibrous outer portion, smooth muscle cells, fibronlast, bundles of collagen)

Question 16

What are the two cells of the corpus luteum?

Answer 16

Granulosa lutein cells and theca lutein cells

Question 17

Briefly describe the properties of granulosa lutein cells

Answer 17

they are 30um in diameter, are centrall located, derived from granulosa cells, and begin to produce progesterone

Question 18

Briefly describe theca lutein cells

Answer 18

15um in diameter, perpherally located cells, derived from cells of the theca internal, are slightly darker staining than granulosa lutein cells, and continue to produce entrogen

Question 19

What are the 6 steps of follicular development?

Answer 19

1) primordial 2) primary 3) secondary 4) vescicular 5) corpus luteum 6) corpus albicans

Question 20

Approx how long are fallopian tubes?

Answer 20

12 cm

Question 21

Where does fertilization of the egg take place?

Answer 21

in the uterine/fallopian tubes

Question 22

The wall of the uterine tubes of comprised of:

Answer 22

folded mucosa with simple columnar epithelium, a thick muscularis, and serosa

Question 23

The two types of cells of the uterine tubes include:

Answer 23

ciliated cells (move oocyte) and secretory cells (darker staining, produce nutrive fluid covering epithelium)

Question 24

What are the three layers of the uterus from inside to outside?

Answer 24

endometrium (simple columnar with both ciliated and secretory cells containing uterine glands), myometrium (middle, thickest layer containnig bundles of smooth muscle separated by connective tissue containing many blood vessels and 4 layes of smooth muscle), perimetrium (outer connective layer, either adventita or serosa)

Question 25

What three types of tissue are present in the vagina?

Answer 25

mucosa, muscle, and adventitia

Question 26

What types of cells line the vagina?

Answer 26

nonkeratinized stratified squamous epithelium

Question 27

What types of muscular layers line the vagina?

Answer 27

inner circular and outer longitudinal
