The total supply of eggs is determined by the time a female is born
Ability to release eggs begins at puberty with the onset of the menstrual cycle
Reproductive ability ends at menopause
Oogenesis - process of producing ova (eggs) in a female
Oogonia - female stem cells found in a developing fetus
Oogonia undergo mitosis to produce primary oocytes that are surrounded by cells that form primary follicles in the ovary
FEMALE REPRODUCTIVE FUNCTIONS AND CYCLES
46

female stem cells found in a developing fetus
Oogonia
50
Oogonia undergo _____ to produce __________ that are surrounded by cells that form ________ in the ovary
Mitosis
Primary Oocytes
Primary Follicles
51
causes some primary follicles to mature each month
FSH (Follicle-stimulating hormone)
52
- completed after ovulation only if sperm penetrates the oocyte
- Ovum is produced
- Two additional polar bodies are produced
Meiosis
53
This is what the sperm penetrates in Meiosis
Oocyte
54
Result of Sperm penetrating the oocyte during meiosis
Ovum
55
Once ovum is formed, the 23 chromosomes can be combined with the 23 chromosomes of the sperm to form the FERTILIZED EGG called?
Zygote
56
In meiosis, males produce what?
4 functional sperm
57
In meiosis, female produces what?
Produces one functional ovum and three polar bodies
58
tiny, motile, and equipped with nutrients in seminal fluid
Sperm
59
large, is nonmotile, and has nutrient reserves to nourish the embryo until implantation
Egg
60
Appears between 11 and 13 years
Marked by menarche (1st menstruation)
Changes are the result of the increase rate of estrogen and progesterone secretion of the ovaries
Before puberty, estrogen and progesterone are secreted in very small amounts
At puberty, the cyclical adult pattern of hormone secretion is gradually established
PUBERTY
61
This hormone is produced by follicle cells
Estrogens
62
These affects secondary sex characteristics
Estrogen
63
causes reuptake of calcium ions, making bone density higher.
Estrogen
64
produced by the corpus luteum
Production continues until LH diminishes in the blood
produced by the corpus luteum
Production continues until LH diminishes in the blood
Does NOT contribute to the appearance of secondary sex characteristics
Other Major Effects (Helps maintain pregnancy by inhibiting the contraction of myometrium, Prepares the breasts for milk production)
Progesterone
65
Release of an oocyte from ovary
Ovulation
66
1. Follicular Phase
2. Ovulation Phase
3. Luteal Phase
Ovarian Cycle
67
the ovarian follicles mature and get ready to release and egg.
rise in the follicle stimulating hormone (FSH) during the first days of the cycle, a few ovarian folliclws are stimulated.
folliclws compete with each other for dominance, follicle that reaches maturity is called tertiary, or Graafian follicle, and it contains the ovum
Follicular Phase
68
follicle compete with each other for dominance, follicle that reaches maturity is calle
Graafian follicle
69
release of hormone matured the egg and weakens the wall of the follicle in the ovary, causing the fully developed follicle to release its secondary oocyte thus becomes matured ovum
LH
70
The pituitary hormones FSH and LH cause the remaining parts of rhe dominant follicle to transform into the corpus luteum, which produces progesterone/estrogen
hormones produced by the corpus outeum also suprress production of the FSH and LH that the corpus luteum needs to maintain itself.
loss of corpus luteum is prevented by fertilization of the egg.
Luteal Phase
71
The pituitary hormones _____ cause the remaining parts of rhe dominant follicle to transform into the corpus luteum, which produces ______
FSH and LH, Progesterone/Estrogen
72
Loss of corpus luteum is caused by _____
prevented by fertilization
73
Cyclic changes of the endometrium, about 28 days in length
Regulated by cyclic production of estrogens and progesterone by the ovaries
FSH and LH, from the anterior pituitary, regulate the production of estrogen and progesterone by the ovaries
Ovulation typically occurs about midway through cycle, on day 14 (day of ovulation)
Uterine (Menstrual) Cycle
74
Days of menstrual cycle
28 days
75
What day does ovulation occur?
Day 14
76
STAGES OF MENSTRUAL CYCLE
Day 1-5: Menstrual Phase
Day 6-14: proliferative stage
Days 15-28: Secretory Phase
77
Functional layer of the endometrium is detached
Bleeding occurs for 3 to 5 days
Ovarian hormones are at their lowest levels
By day 5, growing ovarian follicles are producing more estrogen
Serves as a sign that a woman has not become pregnant
Proliferative Stage
Day 1-5: Menstrual Phase
78
Regeneration of functional layer of the endometrium, increase in blood supply
Endometrium is repaired, thickens, velvety and becomes well vascularized
Estrogen levels rise
Ovulation occurs in the ovary at the end of this stage due to the sudden surge of LH in the blood
Day 6-14: proliferative stage
79
Levels of progesterone rise by the corpus luteum and increase the blood supply to the endometrium, which becomes more vascular
Endometrium increases in size and readies for implantation
If fertilization occurs: Embryo produces a hormone that causes the corpus luteum to continue producing its hormones
If fertilization does NOT occur: Corpus Luteum degenerates as LH blood levels decline, The phases are repeated about every 28 days
Days 15-28: Secretory Phase
80
Consist of mammary glands which are considered the organ of milk production
Before puberty, the breasts of males and females are similar. However, female breast begins to enlarge during puberty, under the influence of estrogen and progesterone
BREAST
81
normally functions in women due to the production of milk
modified sweat glands
increase in size during puberty due to sex hormones (estrogen)
consists of 15-25 lobes, which is separated by connective tissues and fats
each lobe contains smaller chambers “lobules” (contains clusters of alveolar glands = production of milk = lactiferous duct = nipple
Mammary Glands
82
Areola - central pigmented area
Nipple - producing central area of areola
Lobes - internal structure that radiate around nipple
Lobules - located within each lobe and contain clusters of alveolar glands
Alveolar Glands - produce milk when a woman is lactating (producing milk)
Lactiferous ducts - connect alveolar gland to nipple
Lactiferous sinus - dilated portion where milk accumulates
Parts of the Mammary Gland
83
x-ray examination that detects breast cancers to small to feel
American Cancer Society recommends mammography annually for women between 45 and 54 years old and every 2 years thereafter if the results are normal
Breast cancer is often signaled by a change in skin texture, puckering, or leakage from the nipple
Mammography
84
Cessation of menstrual cycle
Caused by age-related changes in the ovaries
Follicles are less sensitive to stimulation of the FSH & LH
Climacteric - from onset of irregular cycles up to the cessation of menstrual cycle
MENOPAUSE
85
time from fertilization until infant is born
Pregnancy
86
developing offspring
Conceptus
87
period of time from fertilization until week 8
Embryo
88
week 9 until birth
Fetus
89
from date of last period until birth (approximately 280 days)
Gestation period
90
Pregnancy - time from fertilization until infant is born
Conceptus - developing offspring
Embryo - period of time from fertilization until week 8
Fetus - week 9 until birth
Gestation period - from date of last period until birth (approximately 280 days)
PREGNANCY AND EMBRYONIC DEVELOPMENT
91
Begins when sperm cell penetrates into the cytoplasm of the secondary oocyte
FERTILIZATION
92
An oocyte is viable up to 24 hours after ovulation
Sperm are viable up to 48 hours after ejaculation
For fertilization to occur, sexual intervourse must occur no more than 2 days before ovulation and no later than 24 hours after
Sperm cells must make their way to the uterine tube for fertilization to be possible
Sperm cells are attracted to the oocyte by chemicals
