31
Male Sex Hormones
Testosterones
32
Two pituitary gonadotropins
luteinizing hormone (LH) stimulating hormone (FSH)
33
The testicular target cells of LH are what cell?
Leydig Cell
34
The testicular target cells of FSH are what cell?
Sertoli Cells
35
The internal genitalia include a three-part system of ducts:
the uterine tubes, the uterus, and the vagina.
36
The ovaries produce
egg cells and release them for fertilization
37
The ripe egg travels along the fallopian tube to the uterus, the____________ in which it develops into an embryo and then fetus.
Muscular sac
38
Germ cells from yolk sac migrate to ovary and become potential egg cells called
oogonia
39
In fetus, ________ of oögonia produced by mitosis but most of them degenerate (atresia)
millions
40
develop into immature egg cells called
oöcytes
41
Each month about how many primary oöcytes become secondary oöcytes
20
42
Contain oöcytes (egg cells) and Secrete estrogens (granulosa cells)
Ovarian Follicles
43
Estrogen Functions
~ Growth and repair of uterine lining ~ Regulation of monthly female cycle ~ Female sexual characteristics ~ Maintenance of bone and muscle
44
After ovulation, empty follicle becomes
corpus luteum
45
completes the preparation of uterine lining
Progesterone
46
work with progesterone
Estrogens
47
decreases secretion of FSH and LH
Inhibin
48
relaxes uterine muscles and pubic symphysis
Relaxin
49
A white scar tissue left after the corpus luteum dies
Corpus albicans
50
A cycle that is complex and controlled by many different glands.
Menstrual Cycle
51
The four phases of the menstrual cycle are
menstruation follicular phase ovulation luteal phase
52
The average length of the menstrual cycle is
28–29 days
53
The elimination of the thickened lining of the uterus (endometrium) from the body through the vagina
Menstruation
54
It contains blood, cells from the lining of the uterus (endometrial cells) and mucus.
Menstrual fluid
55
It is a phase that starts on the first day of menstruation and ends with ovulation
Follicular phase
56
This hormone stimulates the ovary to produce around five to 20 follicles.
follicle stimulating hormone (FSH)
57
The growth of the follicles stimulates the?
lining of the uterus
58
The release of a mature egg from the ovary
Ovulation
59
Ovulation is triggered by the high levels of what hormones
LH. Luteinizing Hormones
60
The life span of the typical egg is only around?
24 hour
61
A phase where ruptured follicle stays on the surface of the ovary
Luteal Phase
62
It cause the lining of the uterus to fall away
Drop of progesterone levels. Known as Menstruations
63
Cessation of menstrual cycle - ages 40-50
Menopause
64
What happens during Menopause?
Menstrual cycle become less regular Ovulation is inconsistent
65
Female sex hormones are
estrogens and progesterone
