Female Reproduction Flashcards
List the primary organs of the female repro system
ovaries
List the accessory organs of the female repro system
uterine tubes, uterus, vagina, vulva
Describe where the broad ligament is attached to
supports the uterus, fallopian tubes, and ovaries
Describe where the ovarian ligament is attached to
connects ovaries to later part of the uterus
Describe where the suspensory ligament is attached to
anchors for the ovaries
Which of the ligaments of the female repro system is the largest?
broad ligament
What is found in the cortex of the ovary?
primordial follicles
What is contained within the medulla of the ovary
blood vessels
What is meant by primordial follicle and what is within the primordial follicle?
primordial follicles are single large cells surrounded by epithelial cells, contain the primary oocyte
How many primary oocytes does a female have at the time of birth? Puberty?
About one million; 400,000
How many primary oocytes are released from puberty throughout?
fewer than 400-500
What is FSH and where does it come from?
follicle stimulating hormone, anterior pituitary
What does FSH stimulate concerning female reproduction?
maturation of follicles
What are granulosa cells?
primordial follicle become the primary follicle with zona pellucida surrounding oocyte
What is the zona pellucida?
Layer of glycoprotein that gradually separates primary oocyte from granulosa cells
When does a primordial follicle become a primary follicle?
when the zona pellucida separates the primary oocyte from the granulosa cells
What is the antrum?
Fluid filled cavity that lies behind the ooctye; helps push it out of follicle
When does a primary follicle become a secondary follicle?
after meiosis I
What is the theca interna?
inner vascular layer with steroid-secreting cells, loose connective tissue and blood vessels
What is the theca externa?
tightly packed connective tissue
When does the secondary follicle become the Graafian or pre-ovulatory follicle?
at about 10-14 days maturation
How is oogenesis different from spermatogenesis?
there is an unequal division of cytoplasm after meiosis I creating a large cell (secondary oocyte) and a small cell (first polar body) in the female
Which oocyte can become the future egg?
the secondary oocyte
How long does it take for maturation of the follicle?
10-14 days
What is inside the Graafian follicle?
secondary oocyte, thick zona pellucida, corona radiata
What is the corona radiata and what is the function?
supply nutrients to secondary oocyte
