Q

-tube walls have smooth m & folded ciliated mucosa
-tubes are sites of fertilization/ passage way of fertilized egg (zygote) to uterus
-beating of cilia & m contraction propel non-motile egg toward uterus
-end that opens to peritoneal cavity has ciliated fimbriae (direct egg into mouth of tubes)

16
Q

-hollow thick-walled organ anterior to rectum & posterosuperior to bladder
-Fxn: receive, retain & nourish fertilized ovum

A

Uterus ( womb)

17
Q

2 parts of uterus

A

-body (larger part): fondus (top segment lying b/w entrance to Fallopian tubes & isthmus (narrow segment)

-cervix (neck or outlet): narrow outlet; projects into vagina

18
Q

3 layers of the uterus wall

A

-perimetrium: thin, outer serous layer (continuous w/visceral peritonieum)
-myometrium: thick muscular middle layer (made up of smooth mm & contracts during menstruation, labour & organisms)
-endometrium: mucosal lining (site of embryo implantation consists of 2 layers: fxnal (cyclic changes) & basal: replenishes fxnal layer cells)

19
Q

-thin-walled tube, 8-10 cm long b/w rectum & bladder
-distal opening may be closed by the hymen (flexible, vascular membrane)
(Has opening for menstrual flow & hymen rupture may result in bleeding)

A

Vagina (birth canal)

20
Q

-adipose tissue + mammary glands + CT
Both male & female have them
-female are functional for lactation

A

Breasts

21
Q

Anatomical feature of breasts

A

-areola: central ring of pigmented skin with large sebaceous glands that produce sebum to prevent charting
-nipple: contains the opening of milk ducts & smooth mm fibers-controlled by ANS, erection of nipple & large sebaceous glands that secrete sebum

22
Q

Mammary glands develop during which trimester or pregnancy?

A

3rd

23
Q

-contain 15-25 lobes per breasts; open at nipple
-separate by fat & CT
-consist of smaller lobular sizes that have glandular alveoli (produce milk)
-milk passes from alveolar glans to lactiferous ducts & sinuses (opens at nipple)
-milk is stored in lactiferous sinus

A

Mammary glands

24
Q

-stimulate development of reproductive organs
-affect metabolism and neural activity

A

Sex hormones

25
Q

Tropic hormones (gonadotropins)
Ovarian follicles development, ovum maturation (estrogen production)?

Triggers ovulation (somatic), stimulates hormone production (tropic)?

A

-FSH
-LH

26
Q

Somatic hormones secreted by ant pituitary?

A

Prolactin: promotes mil production in mammary glands

27
Q

Somatic hormones produced by specialized cells in the ovary?

A

-estrogen
-progesterone

28
Q

-at puberty, stimulates growth/ maturation of genitalia & breasts
-promotes follicle growth in ovary & maturation of eggs
-stimulates myometrium during pregnancy
-growth spurt during adolescence 11-12
-enhances skeletal maturity 15-17
-promotes 2* sex characteristics development (breasts, widening pelvis, hair, fat)

A

Estrogen

29
Q

-secretory changes in endometrium in 2nd 1/2 of monthly cycle prepares uterus wall for implantation
-decrease uterine contraction
-w/estrogen- establishes+ regulates uterine cycle & breast growth
-prepares breasts for lactation
-promotes diuresis (urine formation)

A

Progesterone

30
Q

-process in which 1* oocytes (immure egg cells) undergo mitosis
-produces 2* oocytes
-females thought to be born w/life supply of egg cells
-at birth 2 million 2* oocytes in ovaries

A

Oogenesis

31
Q

2 month cycles:
Ovarian?
Uterine (menstrual)?

A

Ovarian: maturation of egg cell
Uterine (menstrual): cyclical hyperplasia of endometrium

32
Q

Uterine cycle

A

-menstrual phase (uterine endometrium sheds)
-proliferation (endometrium regenerates)
-secretory (preparing endometrium to accept fertilized egg)

33
Q

Ovarian cycle

A

-follicular phase
-ovulation
-literal phase

34
Q

-follicle= cluster of cells around occytes; responsible for its development
Follicle grows & matures
-meiosis & production of 2* occyte
-increase estrogen

A

Follicular phase (days 1-14)

35
Q

-follicle bursts & release oocyte
-1-2% of population will release more than one egg at a time= fraternal twins

A

Ovulation

36
Q

-conversion of follicle to corpus luteum
-increase progesterone

A

Literal phase ( 14 days)

37
Q

Produce and secrete releasing hormones and gonadotropins

A

Hypothalamus and pituitary glands

38
Q

Produce and secrete estrogen and progesterone

A

Ovaries
