Q

Testis

A

Gland in scrotum that produces sperm and male hormones

22
Q

Tunica albuginea

A

Dense connective tissue covering testis; divide it into lobes; support penis rigidity and length, erectile tissue, and temperature regulation

23
Q

Seminiferous tubules

A

Where sperm are produced in testis, coiled in the lobes

24
Q

Rete Testis

A

Tubules converge here, help move sperm from testicle to epididymis

25
Q

Interstitial cells

A

Responsible for production and secretion of testosterone

26
Q

Mons pubis

A

Cushioning and protection

27
Q

Labia Majora

A

Contain glands and adipose tissue; homologous to scrotum (protect urethra and vagina)

28
Q

Labia minora

A

Contains glands; protect urethra and vagina

29
Q

Vestibule

A

B/w labia minora
Contains clitoris, external urethral orifice, vaginal orifice

30
Q

Clitoris

A

Erectile tissue; homologous to penis

31
Q

Perineum

A

Between anterior end of vaginal fold, ischial tuberosity and anus

32
Q

Prepuce (of clitoris)

A

Hood of clitoris, protection

33
Q

Vagina

A

Extends from vestibule to uterus; receive penis and semen during sex

34
Q

Uterus

A

Muscular organ; fertilized egg implants and houses fetus during development
Body (major part)
Fundus (top part near tube entry)

35
Q

Cervix

A

Narrow end of uterus; allow flow in/out of uterus

36
Q

Endometrium

A

Mucosal lining of uterus
Made of functional layer (stratum functionalis)
This is the layer that gets shed
And deep basal layer (Stratum basalis) forms new functional layer after menstruation

37
Q

Uterine (Fallopian) tubes

A

Transport of egg and fertilization site

38
Q

Fimbriae

A

distal end of fallopian tube; “connect” the gonad (ovary) with uterine tube; catch egg when released by ovaries and move it through the tube

39
Q

Broad ligament

A

Drapes over superior uterus; anchors uterus and tubes to lateral body walls

40
Q

Mesometrium

A

part of broad ligament that supports uterus laterally

41
Q

Supporting ligaments

A

Helps maintain position and shape of uterus during pregnancy

42
Q

Myometrium

A

Smooth muscle of the uterus that expands and contracts during labor

43
Q

Nipple

A

Where milk flows to the outside

44
Q

Lobes/lobules of mammary glands

A

Gland and location that makes milk
Lobules make up lobes

45
Q

Alveoli

A

Produce milk during lactation
Located in lobules

46
Q

Lactiferous ducts

A

Ducts that converge and form branched system connecting nipple to lobules; alveoli drain here

47
Q

Menstrual cycle

A

Learn/diagram the whole thing
Video
Etc.

48
Q

3 stages of menstration

A

Menstrual, proliferative, secretory

49
Q

Menstrual

A

Functional layer of endometrium shed
Before ovulation- follicular phase

50
Q

Proliferative

A

Functional layer of endometrium is rebuilt due to estrogen influence
Estrogen also causes spike in LH and FSH in this phase
Before ovulation- follicular phase

51
Q

Secretory

A

Immediately after ovulation under influence of progesterone, enrichment of blood supply and glandular secretion of nutrients prepare endometrium to receive embryo
Luteal phase
