20
Q

Why is the vaginal vault acidic

A

because it helps protect it from infection within the vaginal vault. Alkaline helps neutralize it

21
Q

Prostate Gland

A

Chestnut size, doughnut shaped gland at the base of the urinary bladder through which the prostatic urethra passes through

Secretes alkaline fluid

13-33% of semen volume

22
Q

Bulbourethal Cowpers Gland

A

Pea sized gland located beneath prostate gland.

Secretes mucous

Pre-Ejaculation -> lubrication of the penile urethra

23
Q

Semen

A

Mixture of sperm and other secretions

Average volume - 2.5 to 6 ml

pH range - 7.35 - 7.50

24
Q

Functions of semen

A

Transport medium (nutrition) to support mitotic activity

Capacitation - enzymatic activation of sperm

Mixing occurs to help flagella move

25
Q

Seminalplasmin

A

kills bacteria destruction of the sperm

26
Q

Posterior View of Vas Deferens

A

Ureters

Ductus Deferans

Seminal Vesicles

Ejaculatory Ducts
Ductus Deferens
Seminal Vesicle Ducts

Prostate Gland

Prosthetic Urethra

Bulbourethral Glands

Penile Urethra

27
Q

Anterior Pituitary of FSH

A

Follicle Stimulating Hormone

Initiates spermatogenesis during and after puberty.

In males it increases sperm production

28
Q

ICSH

A

Interstitial Cells Stimulating Hormones aka Lutenizing Hormone

Stimulates leydig cells to produce testosterone

29
Q

DHT

A

Made from Testosterone

Dihydrotestosterone

Masculination hormone ie facial and body hair; Increase balding

Increase male libido and aggressiveness. Anabolic

30
Q

Testosterone of Testes

A

male androgenic hormone.

Anabolic.

Develop body mass and bone density

31
Q

Functions of Testes

A

Controls Growth development and maintenance of sex organs

Stimulate bone growth, protein anabolism

Involved in sexual behavior and maturation of sperm

Secondary sex characteristics which increase hair, increase mascularity and enlarged thyroid cartilage

32
Q

Female Reproductive System

A

Ovaries

Uterine or Fallopian Tubes

Uterus or womb

Vaginal

Vulva

Mammary Glands

33
Q

Ovaries

A

Produce eggs

The female gonad

Paired glands

Slightly larger than almond

34
Q

Vulva

A

external genitalia from the outside

35
Q

Location of Ovaries

A

Upper pelvic cavity on each side of uterus

36
Q

Function of Ovaries

A

produce eggs and female hormones

37
Q

Ovaries anchored by what two ligaments?

A

Ovarian Ligament

Suspensory Ligament

38
Q

Ovarian Ligament

A

attaches ovary to uterus

39
Q

Suspensory Ligament

A

attaches lateral surface of ovary to lateral pelvic wall

40
Q

Uterine or Fallopian Tube

A

Muscular tube by which eggs travel to uterus

5 inches long

41
Q

Infundibulum

A

Expanded end of the Fallopian Tube

Expanded end, closest to ovary

42
Q

Fimbria

A

finger like projections and the infundibulum end that serve to catch the ovum after expulsion from ovary

43
Q

Cilia

A

line the inside of the tube. Along with smooth muscle both propel ovum to uterus.

Peristalsis movement

Journey takes 3-4 days

Fertilization occurs in the lateral 1/3 of the fallopian tube

44
Q

Uterus

A

small pear shaped organ lying in the pelvic cavity

Normal position is anteflexed which bend anterior over the bladder.

Flexed more forward

45
Q

Uterus is anchored by what?

A

Broad ligament

Round ligament

46
Q

Broad Ligament

A

extensive mesentary that covers both uterus and ovaries

Imagine a big sheet and it is hung over the body and the sheets that come together on both sides, would be the broad ligament

47
Q

Round Ligament

A

Arises off the lateral uterus behind and below the uterine tube. They connect anteriorly to a part of the external genitalia but to lateral wall of the pelvic cavity.

48
Q

Lateral Ligament

A

connect the uterus to the lateral pelvic wall.
