Q

menarche

A

first period bleeding

18
Q

male accessory glands =

3 exocrine glands

A
  • seminal vesicles
  • prostate gland
  • bulbourethral glands
19
Q

ovarian cycle

A
  1. follicular phase
  2. ovulation
  3. luteal phase
20
Q

maturation and transformation of ovarian follicle

A
  1. primordial follicle
  2. primary follicle
  3. secondary follicle
  4. mature follicle
  5. corpus lute
  6. corpus albicans
21
Q

menstrual

A
  • spiral glands become necrotic, sloth into the uterine lumen
  • necrosis of functional layer: necrotic endometrium, mucous secretions, small amount of blood released from spiral arteries make up the fluid
  • constriction of spinal arteries
  • contraction of uterine smooth muscle
22
Q

hormone secretion in female

A
  1. hypothalamus
  2. pituitary gland
  3. ovaries
  4. uterus
23
Q

oogonia

A

female stem cells gives rise to oocytes

24
Q

acetylcholine

nitric oxide

A

(neurotransmitters) cause smooth muscle relaxation in the erectile tissue during erection

25
Q

layer surround a primary oocyte:

A

zona pellucida

26
Q

spermiogenesis = late spermatogenesis

A

differentiation of spermatid into a single, mature spermatozoon

27
Q

spermatic cord includes:

A
  • blood vessels/testicular artery and vein
  • testicular nerves (autonomic nerve fibers)
  • ductus (vas) deferens
  • cremaster muscle
28
Q

mammary glands

A
  • organs of milk production
  • located within breasts
  • are modified sweat glands
29
Q

interstitial cells / Leydig produce:

A

testosterone

30
Q

what is hymen

A

membrane stretches across the vaginal outlet

31
Q

single-celled fertilized egg:

A

zygote

32
Q

eggs develop within encircling structure within ovary is:

A

follicles

33
Q

events prior to birth,

A
  • formation of oogonia
  • formation of primary oocytes
  • beginning of prophase 1 i oogonia
34
Q

corpus luteum secretes

A

estrogen and progesterone

35
Q

ejaculatory duct is a convergence of:

A

seminal vesicle and the ductus deferens

36
Q

What hormone is highest level during the luteal phase?

A

progesterone

37
Q

placenta: function

A
  • removes fetal wastes
  • provides nutrients
  • secretes hormones
38
Q

uterine tube consists of (3 layer):

A

superficial to deep

  1. serosa
  2. muscular layer
  3. mucosa
39
Q

inhibin in male

A
  • inhibin = protein hormone that inhibits secretion of FSH from anterior pituitary, GnRH from hypothalamus.
  • when the sperm count falls, secretion declines steeply.
40
Q

greater vestibular glands

A

release mucus into the vestibule and keep it moist to lubricate, facilitate intercourse
