Q

Female Reproductive System - Seven steps (1)

A

1) An immature follicle is composed of a primary oocyte and its granulosa cells
2) Development begins stimulated by FSH; granulosa cells begin to divide
3) A fluid-filled antrum develops; follicles begin to develop estrogen
4) The follicle matures; estrogen secretion continues
5) Ovulation occurs; stimulated by LH, the follicle ruptures realising the secondary oocyte
6) The corpus lutuem produces estrogen
7) The corpus lutuem degenerates if pregnancy does not occur

27
Female Reproductive System - Uterus
Opening to uterus
28
Female Reproductive System - Vagina
Birth Canal
29
Mammary glands (2)
1) Modified sweat glands | 2) Hormonal control of lactation
30
Mammary glands - What do the modified sweat glands provide?
1) MILK
31
Mammary glands - Hormononal control of lactation - what two hormones regulate the control of lactation
1) Prolactin - stimulates production | 2) Oxytocin stimulates milk ejection
32
Menstrual Cycles (4)

33
Menstrual Cycles - Duration?
1) 28 days
34
Menstrual Cycles - Ovarian cycle
Prepares Ova
35
Menstrual Cycles - Uterine Cycle
Prepares endometrium
36
Menstrual Cycles - Hormone control (4)
1) FSH, LH - pituitary | 2) Estrogen and progesterone - ovaries
37
Ovarian Cycle (3)
1) Follicular phase (1-14) 2) Ovulation (14) 3) Luteal Phase (14-28)
38
Ovarian Cycle - Follicular phase (2)
1) Maturing follicles (eggs) | 2) Follicular cells secrete estrogen
39
Ovarian Cycle - Ovulation day?
Ovulation occurs in day 14
40
Ovarian Cycle - Luteal Phase (3) day? remaining follicular cells? what is been secreted during this time?
1) 14-28 2) Corpus Luteum 3) Secrets estrogen and progesterone
41
Uterine Cycle (3)
1) Menstrual phase 2) Proliferative Phase 3) Secretory phase
42
Uterine Cycle - Menstrual phase? days? What is it? Hormones levels and which one
1) 1-6 days 2) Menstruation - the shedding of layer 3) Triggered by a drop in estrogen and progesterone
43
Uterine Cycle - Proliferative Phase days? What is it? Estrogen levels?
1) 6-14 2) Repairs Uterine walls 3) High estrogen
44
Uterine Cycle - Secretory phase days what is it estrogen levels

What is an endometrium?
The endometrium is the innermost lining layer of the uterus
46

55
Enhancing Fertility - Vitro Fertilization
Fertilization outside body in a test tube. After several cell divisions, the embryo is inserted into endometrium uterus) via vagina a.k.a pussy
