Ovary Anatomy And Oogenisis Flashcards
Ovary consists of what 2 main sections
Outer cortex and inner medulla
The outer cortex holds what
Oocyte said
Oocytes are held in what tiny sacs
Follicles
Inner medulla contain what
Nerves and blood vessels
Blood vessels in medulla assist in what
Delivery of hormones that regulate oogenesis
Initial diploid stem cells that will become oocytes are called what
Oogonia
The Oogonia, after mitosis becomes a what
Primary oocyte
Primary oocyte is contained in what
Primordial follicle
The primary oocyte is formed when and arrested at what phase
Before birth, arrested in prophase 1
The ovary is functionally inactive when
Infancy and childhood
From puberty to menopause, the primary follicle develops into what each month in terms of follicles
Primary > secondary > vesicular (antral)
In terms of follicle development, after vesicular/antral follicle, what phase is it in and what happens to the secondary oocyte
Metaphase 2, secondary oocyte is ovulated. Follicle is ruptured and degenerates
How many primary oocytes complete meiosis 1 each month
One
Meiosis 2 will only be completed if what occurs
Fertilisation
After completion of meiosis 1, how many daughter cells are formed and how many can go on to develop
2 daughter cells and one can develop
The daughter cell that can develop produces what and what happens to the non viable polar body
Viable daughter cell turns into secondary oocyte. Non viable may undergo 2nd meiotic division
What is the polar body
Non viable daughter cells with no cytoplasm
What is the Antrum
The space filled with clear fluid between the oocyte and surrounding follicles
Ovulation is what
The bursting of the Antrum causing the secondary oocyte to release
What is mittelschmerz
The pain felt by some in lower abdomen when ovulation occurs. Stretching and rupturing of ovarian wall
The remnants of the follicle after ovulation develops into what structure known as
Temporary hormone producing structure known as corpus let rum
Corpus letuem produces what
Progesterone
Another word for puberty
Menarche
Menstrual cycles stimulate maturation of what
Primordial follicles
