Q

ovary oocyte production: Oogenesis

A
  1. begins from oogonia (oocyte stem cells)

2. oogonia undergo mitosis to produce oocytes before birth

Q

A
  • contained in ovaries from birth until puberty

- composed of simple squamous epithelium surrounding the oocyte

Q

primary follicle

A

each month, in response to FSH, primordial follicles mature into primary follicles
-epithelial cells now called granulosa cells enlarge, divide to form stratified epithelium, and begin to produce estrogen

Q

secondary follicle

A

matured primary follicles

-epithelial cels continue to produce estrogen and begin to secrete fluid that creates a space around oocyte

Q

tertiary follicle

A

1 mature secondary follicle

  • small spaces fuse to create larger cavity (antrum)
  • oocyte:
    1. bulges into antrum
    2. separates from follicle
    3. floats freely in antrum
  • epithelial cells produce a lot of estrogen, leading to an estrogen surge

Q

steps of ovulation

A
  1. estrogen surge from tertiary follicle leads to LH surge
  2. LH surge leads to ovulation: release of oocyte from tertiary follicle
  3. empty follicle develops into corpus luteum

Q

function of corpus luteum

A

its epithelial cells start to produce progesterone in order to prepare the uterine lining for pregnancy

Q

if fertilization does not occur…

A

the corpus luteum degenerates and fills with scar tissue to become the corpus albicans

Q

review of hormonal regulation of ovary (FELP)

A 
(F)- FSH causes follicles to mature
(E)- estrogen is produced by follicles
(L)- LH is produced
        -ovulation occurs
(P)- progesterone is produced by corpus luteum

Q

follicular phase of ovarian cycle

A
  • primordial thru tertiary follicles
  • stimulated by FSH
  • primary sex hormone produced is estrogen

16
Q

luteal phase of ovarian cycle

A
  • corpus lutuem and albicans are formed
  • LH production
  • primary sex hormone produced is progesterone
17
Q

uterine tubes

A

aka fallopian tubes

  • hollow, muscular tubes
  • transport oocyte from ovary to uterus
  • where fertilization occurs
18
Q

components of uterus

A
  1. body

2. cervix (neck)

19
Q

function of uterus

A

provides protection, nutrition, and waste removal for a developing fetus

20
Q

perimetrium

A
  • outer layer of uterine wall
  • made of epithelium and CT
  • continuation of broad ligament
21
Q

myometrium

A
  • middle layer of uterine wall
  • very thick, smooth muscle
  • provides force to move fetus out of uterus into vagina
22
Q

endometrium

A
  • inner layer of uterine wall
  • glandular and vascular
  • supports growing fetus
  • growth of this layer is stimulated by estrogen and progesterone each month
23
Q

uterine cycle

aka menstrual cycle period

A

a repeating series of changes in the endometrium

  • lasts 21 to 35 days
  • responds to hormones of the ovarian cycle
  • consists of 3 phases
24
Q

menses

A
  • 1st phase of uterine cycle
  • consists of destruction of outer layer of endometrium
  • results in release of blood and tissues
  • stimulated by decr. in progesterone
25
Q

proliferative phase

A
  • 2nd phase of uterine cycle
  • results in repair and regeneration of endometrium
  • stimulated by estrogen secretion by follicles
26
Q

secretory phase

A
  • 3rd phase of uterine cycle
  • begins at ovulation
  • results in secretion by glands in the endometrium and rapid growth of arteries
  • stimulated by progesterone secretion by corpus luteum
27
Q

relationship between menstrual and proliferative phases of uterine cycle and follicular phase of ovarian cycle

A

both phases of uterine cycle occur during follicular phase

28
Q

relationship between secretory phase of uterine cycle and luteal phase of ovarian cycle

A

secretory occurs during luteal

29
Q

vagina

A
  • elastic, muscular tube
  • extends from cervix to vestibule
  • functions as a passageway for menstrual fluids, spermatozoa, and birth canal
30
Q

clitoris

A

erectile tissue

equivalent to penis in males

31
Q

labia majora

A
  • adipose tissue
  • protects inner structures
  • covered with pubic hair
32
Q

labia minora

A
  • medial to labia majora

- not covered with pubic hair

33
Q

vestibule

A

space between the flaps of the labia minora

-contains openings for urethra and vagina

34
Q

mammary glands

A
  • lie in pectoral fat of boobs
  • composed of lobes
    • each contains secretory lobules
      • which drain milk into lactiferous ducts
  • nipple contains openings of lactiferous ducts
  • areola is skin around nipple
  • milk secretion is controlled by oxytocin
35
Q

female sexual arousal

A
  • parasympathetic activation leads to
    • engorgement of clitoris
    • incr. secretion of mucus in cervix and vestibule
  • orgasm is accompanied by:
    • sympathetic activation
      • contractions of uterus
    • somatomotor activation
      • contractions of skeletal muscles surrounding clitoris
