22
Q

Describe featuresof isthmus of cervix

A

It is the upper 1/3 of cervix, it resembles uterine body in structure. In non-pregnant women it undergoes menstrual changes, during pregnancy it is taken up into body & called lower uterine segment.

23

A

Uterovesical fold
Rectovaginal fold

24
Q

Describe feature of ant border & sup layer of broad ligament

A

-Ant border medial 4/5 contains uterine tube, lateral 1/5 forms suspensory ligament of ovary
-Sup border is connected to Ovary by mesovarium &cis pierced by infundibulum of uterine tube

25
Q

Uterine artery crosses ureter at…….

A

A point about 2 cm from cervix

26
Q

List the fibromuscular ligaments of uterus

A

Transverse cervical, uterosacral, pubocervical, round ligaments of uterus

27
Q

The mesosalpinx in found between………., it contains……..

A

Uterine tube, mesovarium, ovary & ligament of ovary

28
Q

List contents of the broad ligament

A
  1. One tube uterine tube
  2. Two ligaments: round ligament of uterus, ligament of ovary
  3. Two vessels: uterine & ovrian
  4. 2 nerve plexues: uterovaginal & ovarian
  5. 2 embryological remnants, epoophoron& Gartner’s duct + paroophoron
  6. Other: lymphatics & parametrium
29
Q

The ligament supporting uterus is…..

A

Transvrse cervical (cardinal)

30
Q

The ligament which keeps uterus in AVF position is…..

A

Uterosacral

31
Q

The round ligament if uterus hooks around…..

A

Inferior epigastric vessels

32
Q

Describe blood supply of uterus

A

Art: uterine artery gives cervical & vaginal branches then ascends in tortuous course giving uterine branches & passes laterally dividing into tubal & ovarian branches within broad ligament
Ven: uterine venous plexus extends along side of uterus plexus drains into uterine, vaginal & ovarian veins

33
Q

List supporting mechanisms of uterus

A
  1. Fibromuscular ligaments
  2. Muscular factors
  3. Perineal body
  4. Surrounding viscera
34
Q

Describe nerve supply & LD of uterus

A

-uterovaginal autonomic plexus from inferior hypogastric plexus
LD: Cervix drains into external & internal iliac & sacral lymph nodes, body to external iliac LNs, uterotubal junction to superficial inguinal LNs, fundus to para-aortic LNs

35
Q

The vaginal fornix covered by peritoneum is

A

Posterior

36
Q

Lateral vaginal fornices recieve attachment of……

A

Mackenrodt’s ligament

37
Q

Describe posterior relations of vagina

A
  1. Lower 1/4 related to anal canal with perineal body in-between
  2. Middle 2/4 is related to rectum with loose fibroareolat tissue in-between
  3. Upper 1/4 is related to rectum with rectovaginal pouch in-between
38
Q

Describe lateral relations of vagina

A

Lower part: related to Greater vestibular glands with perineal body in-between & muscles of urogenital diaphragm
Middle part related to sphincter vaginae (part of levator ani)
Upper part gives attachment to Mackenrodt’s ligament

39
Q

Describe blood supply of vagina

A

-Vaginal branches of uterine artery & branches of vaginal artery (both form azygos artery) + middle rectal & internal pudendal artery
-Drains into vaginal venous plexus which drains into vaginal veins then to internal iliac vein

40
Q

Describe LD & nerve supply of vagina

A

-LD: below hymen superficial inguinal LNs, above it external & internal iliac LNs
-NS: Lower inch is pain sensitive supplied by pudendal nerve through inferior rectal & posterior labial nerves. Remaining upper part of vagina is pain insensitive supplied by uterovaginal plexus from inferior hypogastric plexus.

41
Q

List stages of oogenesis & their outcome

A
  1. Proliferation: primordial germ cells from endoderm of yolk sac, migrate to cortex of ovary & develop into oogonia that proliferate by mitosis giving daughter oogonia early in fetal life.
  2. Growth: 3rd month of prenatal life, oogonia enlarge in size giving 1ry oocyte which enter prophase of 1st meiotic divison & remain arrested in diplotene phase of prophase (46 d-ch, 4N). They are surrounded by single layer of flat epithelial cells giving primordial follicles
  3. Maturation:
    a) Completion of 1st meiotic divison to give 2ry oocyte & 1st polar body (23 d-ch)
    b) Second meiotic divison completed only at fertilization gives ovum & 2nd polar body (23 s-ch)
42
Q

GR: Incidence of Down syndrome inc with mother age

A

As 2ry oocyte remain arrested in 1st meiotic divison for 12-50 yrs. This long period of meiotic arrest exposes 1ry oocyte to adverse environmental influences & may contribute to errors in meiotic divison as nondisjuction.

43
Q

Tunica albuginea is covered from outside by…..

A

Germinal epithelium which simple cubical in yound overy & simple squamous in adults

44
Q

Spiral artery is found in……

A

Stroma of the medulla

45
Q

Medulla of ovary has epithelioid cells called……., their func is…..

A

Hilus cells
Androgen secretion

46
Q

Primordial follicles consists of……., they are found in……

A

1ry oocyte surrounded by single layer of follicular cells
Superficial cortex under tunica albuginea

47
Q

Describe structure of follicular cells in primordial follicle

A

Flat squamous cells joined together by desmosomes & are separted from the vascular CT stroma by basal lamina acts as blood-follicle barrier

48
Q

What is fate of primordial follicle?

A

A group of them is recruited to begin a process of follicular growth, as they grow, they move deeper into ovarian cortex

49
Q

Primordial follicle under effect of…….from…….

A

FSH
1ry follicles

50
Q

Describe EM features of 1ry follicles

A

Numerous mitochondria, more extensive rER & enlarged golgi complex. Formation of secretory granules called cortical granules containing various proteases which undergo exocytosis early in fertilization.
