Ovary Anatomy And Oogenisis

Question 1

Answer 1

Outer cortex and inner medulla

Question 2

The outer cortex holds what

Answer 2

Oocyte said

Question 3

Oocytes are held in what tiny sacs

Answer 3

Follicles

Question 4

Inner medulla contain what

Answer 4

Nerves and blood vessels

Question 5

Blood vessels in medulla assist in what

Answer 5

Delivery of hormones that regulate oogenesis

Question 6

Initial diploid stem cells that will become oocytes are called what

Answer 6

Oogonia

Question 7

The Oogonia, after mitosis becomes a what

Answer 7

Primary oocyte

Question 8

Primary oocyte is contained in what

Answer 8

Primordial follicle

Question 9

The primary oocyte is formed when and arrested at what phase

Answer 9

Before birth, arrested in prophase 1

Question 10

The ovary is functionally inactive when

Answer 10

Infancy and childhood

Question 11

From puberty to menopause, the primary follicle develops into what each month in terms of follicles

Answer 11

Primary > secondary > vesicular (antral)

Question 12

In terms of follicle development, after vesicular/antral follicle, what phase is it in and what happens to the secondary oocyte

Answer 12

Metaphase 2, secondary oocyte is ovulated. Follicle is ruptured and degenerates

Question 13

How many primary oocytes complete meiosis 1 each month

Answer 13

One

Question 14

Meiosis 2 will only be completed if what occurs

Answer 14

Fertilisation

Question 15

After completion of meiosis 1, how many daughter cells are formed and how many can go on to develop

Answer 15

2 daughter cells and one can develop

Question 16

The daughter cell that can develop produces what and what happens to the non viable polar body

Answer 16

Viable daughter cell turns into secondary oocyte. Non viable may undergo 2nd meiotic division

Question 17

What is the polar body

Answer 17

Non viable daughter cells with no cytoplasm

Question 18

What is the Antrum

Answer 18

The space filled with clear fluid between the oocyte and surrounding follicles

Question 19

Ovulation is what

Answer 19

The bursting of the Antrum causing the secondary oocyte to release

Question 20

What is mittelschmerz

Answer 20

The pain felt by some in lower abdomen when ovulation occurs. Stretching and rupturing of ovarian wall

Question 21

The remnants of the follicle after ovulation develops into what structure known as

Answer 21

Temporary hormone producing structure known as corpus let rum

Question 22

Corpus letuem produces what

Answer 22

Progesterone

Question 23

Another word for puberty

Answer 23

Menarche

Question 24

Menstrual cycles stimulate maturation of what

Answer 24

Primordial follicles

Question 25

What 3 things happens during development of follicle cells

Answer 25

Cells become stratified
Deposit clear jelly like layer of glycoprotein around oocyte called zone pellucida
Produce oestrogen

Question 26

What 2 purposes does the ovaries serve

Answer 26

Producing ova and oestrogen + progesterone
