levator prostatae

pubovaginalis

puboperinealis

puboanalis

25
Q

What nerves innervate the levator ani ms?

A

n to levator ani M (S4)

inferior rectal N

branches of coccygeal plexus

26
Q

What nerve innervates coccygeus M?

A

ner to the coccygeus (S4,5, branches of coccygeal plexus)

27
Q

What is the interureteric fold?

A

superior limit of the trigone

28
Q

What is vesical fascia?

A

loose connective tissue surrounding the detrusor M

29
Q

What are the contents of the spermatic cord?

A

ductus deferens

testicular A

A of ductus deferens

cremasteric A

Pampiniform plexus of veins

genital branch of genitofemoral N

30
Q

What are mural granulosa cells?

A

become highly steroidogenic

remain in the ovary after ovulation to differentiate into the corpus luteum

31
Q

What causes the breakdown of the follicle wall to release an egg during ovulation?

A

before ovulation, follicle presses against wall of ovary to form bulge = stigma

LH surge –> inflammatory cytokines and hydrolytic enzymes from theca and granulosa cells –> breakwon follicle wall, tunica albuginea, etc

32
Q

What produces angiogenic factors to increase blood supply to a corpus luteum?

A

granulosa cells

33
Q

What happens to thecal cells after follicular atresia?

A

thecal cells persist and repopulate the cellular stroma of the ovary

have LH receptors and ability to produce androgens

collectively called the interstitial gland of the ovary

34
Q

What is the diagonal conjugate diameter?

A

from inferior edge of pubic symphysis to sacral promontory

35
Q

What structure is often damaged in anterior-posterior crush injuries of the pelvis?

A

urinary bladder

36
Q

Where is the pudendal canal located in the ischiorectal fossa?

A

lateral wall

contains pudenal N and internal pudendal A

37
Q

What lobes are commonly involved in BPH?

A

middle lobes (central zone)

38
Q

Which pelvic floor muscle is likely to tear during childbirth if the perineum tears?

A

pubococcygeus

39
Q

What is a good landmark to find the left ureter?

A

anterior to left common iliac A

40
Q

What ligaments provide direct support to the uterus?

A

cardinal ligament

uterosacral ligament

41
Q

What is the most typical position for the uterus?

A

anteflexed and anteverted

42
Q

What is contained in the pubocervical L?

A

superior vesicle artery and vein

43
Q

What is contained in the male urogenital diaphragm?

A

membranous urethra

bulbourethral glands

deep transverse perineal m

external urethral sphincter

44
Q

What is contained in the female urogenital diaphragm?

A

deep tranverse perineal m

external urethral sphincter m

compressor urethrae m

sphincter urethrovaginalis m

bulb of the vestibule

greater vestibular glands

45
Q

What secretes estradiol in the developing follicle?

A

theca interna

46
Q

How many days after ovulation does the corpus albicans begin to form?

A

14

47
Q

What are the 3 layers from out to in that the sperm needs to get through to get to the oocyte?

A

corona radiata

zona pellucida

plasma membrane

48
Q

What are the 3 steps of capacitation?

A
  1. uterine and fallopian tubes wash away inhibitory factors from sperm
  2. membrane becomes permeable to Ca –> tail more powerful and ready to release stuff
  3. activated sperm
49
Q

When do sperm express ZP-3 receptors?

A

only after capacitation

50
Q

What are the 3 glycoproteins in the zona pellucida and what do they do?

A

ZP-1 = crosslinker

ZP-2 = blocks polyspermy

ZP-3 = initiates acrosome rxn (then falls off)

51
Q

What occurs to sperm immediately after it enters the egg?

A

nucleoli merge and sperm DNA condenses

52
Q

What are the steps of the cortical Rxn

A
  1. ZP-2 –> ZPf –> inhibits entrance of sperm
  2. ca released –> granules also released and egg completes meiosis II
  3. Egg activated - sperm DNA condenses, male and femal pronuclei fuse
53
Q

What are the autocrine growth factor functions of hCG?

A

stimulates trophoblast growth and development

stimulates placental growth

54
Q

What cells can secrete prolactin?

A

decidual cells

55
Q

What are the most high risk strains of HPV?

16 and 18
