Q

In glomerular nephritis, what might you expect to find in urine?

A

Protein or blood cells

19
Q

What does cremaster and dartos muscle do?

A

Both dartos muscle and cremaster muscle regulate temperature of testis

Cremaster muscle covers the testis, moves the testis, guard against injury.

20
Q

Where are sperm produced?

A

Seminiferous tubule in testicles

21
Q

What is the name of the thick white capsule covers testi?

A

Tunica albuginea

22
Q

Which hormone produced by testis?

A

Testosterone

23
Q

What are the Leydig / interstitial cells do?

A

Produce testosterone

24
Q

Undescended testis means what?

A

Both testis fail to move into the scrotum before birth, cause infertility, increase cancer risk
3% full term
30% premature

25
Q

What Sertoli cells do?

Locate in seminiferous tubules

A 
Nourish germ cells
Secrete hormones (androgens, estrogens, inhibin)
Form blood testis barrier  (prevent sperm from escaping into blood stream)
26
Q

What are the structures found in spermatic cord?

A 
Blood vessels (testicular veins and artery)
Nerves (testicular nerve)
Ductus deferens 
Cremaster muscle (cover)
27
Q

Arrange structure sperm pass from seminiferous tubule to end of penis

A 
Seminiferous tubule
Rete testis 
Efferent ductule 
Epididymis
Ductus deferens 
Ampulla
Seminal gland
Ejaculatory duct
Prostatic urethra
Membranous urethra
Spongy urethra
External urethra orifice
28
Q

Ovary is attach to uterus by:

A

Ovarian ligament and broad ligament

29
Q

Primary oocyte counts VS how many ovulated?

A

Primary oocytes before birth 3-5 million
At birth 2 million undergo atresia = ( passage closed or absent)
At puberty 300,000
Only 400 rise to the secondary oocytes = ovulate

30
Q

When does fertilization occur?

A

When sperm meet an egg

Egg stays in Fallopian tube for 24 hours to meet sperm

31
Q

What is zygote?

A

Fertilized egg, a diploid cell

Diploid =containing two complete sets of chromosomes, one from each parent

32
Q

What is corpus luteum?

A

Follicle that ovulated.

Produce progesterone to be ready for pregnancy

33
Q

Pathway of the egg leaves ovary to make it enter the uterus:

A 
Ovary
Peritoneal cavity
Fimbriae
Infundibulum
Ampulla
Isthmus ( where uterus receive tube)
34
Q

Pap smear?

A

Take a scrape on cervix sample to look STI, cancer

35
Q

Most superior Portion of vulva is:

A

Mons pubis

36
Q

What is episiotomy?

A

Surgical incision between vagina and anus to prevent tearing during childbirth

37
Q

What is imperforate hymen?

A

hymen covers the whole opening of the vagina.

38
Q

Fundus

A

Uterine base superior to uterine tube attachment

39
Q

Fimbria

A

Finger-like process receive an ovulated egg

40
Q

Infundibulum

A

Funnel open to peritoneal cavity

41
Q

Ampulla

A

Site for fertilization

42
Q

Corpus luteum

A

follicle after ovulation

Granulosa cells and theca = luteal cells enlarge and secrete progesterone (some estrogen)

43
Q

Ischemic phase

A

Atrophy of corpus luteum resulting menstruation

44
Q

Amenorrhea

A

Absence of menstrual cycle
