Q

The secondary follicle - differentiate from primary follicle
Follicular fluid increase to force the oocyte and some follicular cells move to one side to form a hillock-like structure

A

Cumulus oophorus

17
Q

The theca of follicle is divided into 2 layers

A
  1. Theca interna
  2. Theca externa
18
Q

The Theca interna is

A
  • rich in Theca cells which are the hormone secreting cells
  • spindle shaped, polyhedral
  • steroid hormone cell features
19
Q

The Theca externa is

A
  • connective tissue (CT)
  • fiber
20
Q

The wall of the follicular cavity composed of

A

Stratum granulosum

21
Q

Theca cells and granulosa cells together will produce and secrete

A

Estrogen (main source of sex organ in females)

22
Q

Maximally developed follicle which extends through the full thickness of the cortex and bulges from the surface of the ovary

A

Mature follicle

23
Q

Compared with the secondary follicle, the mature follicle

A
  • increased follicular fluid
  • enlarged follicular cavity
  • thinner stratum granulosa
24
Q

The first meiosis division is completed _______ hours before ovulation

A

36-48

25
Q

During the first meiosis division, the primary oocyte divides into secondary oocyte and the first polar body will

A

Disappear

26
Q

The ______ begins the second meiosis

A

Secondary oocyte

27
Q

After the secondary oocyte begins the second meiosis, it rests at the second stage of division, if fertilized, it becomes an ______, if not fertilized, it perishes.

A

Ovum

28
Q

During the fourteenth day of menstruation, ovum maintain the capacity of fertilization for

A

12-24 hours

29
Q

After ovulation, follicle collapse, CT and blood vessels enter the follicle to form a yellow-colored, gland-like structure

A

Corpus Luteum

30
Q

Corpus luteum of menstruation

A
  • not fertilized
  • exist for 12-14 days, then become corpus albicans
31
Q

Corpus luteum of pregnancy

A
  • fertilization occur
  • exists for 6 months, then becomes corpus albicans
32

Only _____ follicles reach maturity and release oocyte

A

450

33
Q

The degeneration and perishing of follicle at any stage of development and maturation

A

Atretic follicle

34
Q

Originate from Theca interna and surrounding stromal elements of degenerating follicles and are simultaneously vascularized and hypertrophied (or luteinized)

A

Interstitial gland

35
Q

During pregnancy, embryo is embedded in the

A

Functional layer

36
Q
