Female

Question 1

-Why is the ovaries BOTH exocrine and Endocrine

Answer 1

Because it produces and secretes oocytes (gametes)- exocrine

Produce hormones- endocrine !

Question 2

What ae the primary and seconday female sex organs

Answer 2

Primary sex organs: the Gonads (ovaries)

Secondary sex organs 2 groups

1. Interal genitial- oviduct , uterus , vagiina
2. External -vestibule , labia minora, labia major , clitoris

Question 3

What type of epithelium is on the surface of the ovary?

Answer 3

germinal epithelium = simple cuboidal

Question 4

What are the parts of the ovary and what are their fxn?

Answer 4

Surface = germinal epithelium -> simple cuboidal epithelium

• Cortex = ovarian follicles in different stages of development
• Medulla - connective tissue and blood vessels

Question 5

What are the primordial follicles and what stage of meiosis does it occur?

what is outside of the follicular cells?

Answer 5

• oocyte, stromal cells, follicular cell
• Arrested in prophase I (dictyotene) - starts in uterus of baby

stromal cells

Question 6

When do the granulosa cells form?

Answer 6

At puberty FSH is produced causing flat follicular cells to become cuboidal = granulosa cells

Question 7

What are the unilaminar primary follicles?

Answer 7

Have one layer of granulosa cells

Question 8

What are the multilaminar primary follicles and what structure is present?

Answer 8

• Has more than one layer of granulosa cells and has theca interna

Question 9

Stromal cell differentiate to form?

why is this important

Answer 9

differentiate to form theca INTERNA this is important because theca interna produces ANDROSTENEDIONE which diffuses into the primary follicle and metabolizes estrogen!

Question 10

What is the secondary (antral) follicle, what new structure is present? What stage of meiosis does it first appear?

Answer 10

• Has antral space
• Theca externa (connective tissue)
• Prophase II (dictyate)

Question 11

What causes the secondary antral follicle to become arrested in prophase II?

Answer 11

Oocyte Meiosis Inhibitory (OMI)

inhibitory protein

Question 12

What is the graafian or tertiary follicle?

Answer 12

the 1 follicle out of 10 follicles that enters differentiation process and ovulates mid cycle

Question 13

What is the cumulus oophorus and when does it become prominent?

Answer 13

What is the cumulus oophorus and when does it become prominent?

• accumulations of granulosa cells continuous with the pedicle (region where the culmulus oophorus attaches to the other granulosa cells)
• Mature (graafian) follicle

Question 14

What happens during ovulation?

Answer 14

Oocyte Meiosis Inhibitory substance in antral space is disperses so mature follicle (oocyte) is released into fallopian tubes and can now progress from Prophase II to Metaphase II

Question 15

What is the tunica albuginea?

Answer 15

Connective tissue in the reproductive system

Question 16

What is the zona pellucida?

Answer 16

thick layer of proteins (Connective tissue layer) that surrounds oocyte unless fertilization occurs

granulosa cells and oocyte together depositextracellular coat on primary oocyte

Question 17

What is the corona radiata and when does it first appear?

Answer 17

• Tightly packed layer of granulosa cells around zona pellucida
• Mature
  (graafian) follicle

Question 18

At what stage is the oocyte in prohase 1?

Answer 18

primordial , primary oocyte is arrested in prophase one

Question 19

1/10 secondary follicle become ____. The granulosa around this oocyte is called

Answer 19

Mature (graafian follicle) granulosa around mature follicle is call culmulus ophorus!

Question 20

When the graafian follicle ovulates what happens to OMI ? what phase will the oocyte progress to?

Answer 20

OMI is the antral space, when ovulation of mature follicle occurs the OMI disperses so it can no longer arrest the oocyte( which has to leave since ovulating is occurring!)

OOcytes progresses to METHAPHASE II in fallopian tube and remains there unless fertilization occurs

Question 21

Meiosis is complete when

Answer 21

fertilization occurs , when ferilization doesnt occur that is when the oocyte goes into oviduct , FALLOPIAN TUBE!( metaphase II)
