2. Ovary
Overview:
Superficial epi.
Tunica albuginea
Cortex: ovarian follicles
Medulla: CT, vessels

3. Primordial follicle（原始卵泡）:
primary oocyte + flattened follicular cells

4. Primary follicle（初级卵泡）
Primary oocyte
Mutiple cuboidal follicular cells
Zona pellucida

5. Early
Secondary follicle（次级卵泡）
Follicular antrum
Granulosa cells
Theca folliculi

6. Late secondary follicle2 1. 3
1.Stratum granulosum（颗粒层）
2.Cumulus oophorus（卵丘）
3.Corona radiata（放射冠）

7. Follicular atresia
（闭锁卵泡）
Residual refractile zona pellucide

8. Follicular atresia
Developed thecal interna cells interstitial cells（间质细胞）

9. Uterus in the proliferative phase
endometrium
myometrium
perimetrium

10. endometrium
myometrium

11. Endometrium
Epithelium: simple columnar epi.
Lamina propria: C.T+ tubular glands

12. Tubular glands

13. Coiled arteries （螺旋动脉）of the endometrium
Tubular gland
Coiled arteries （螺旋动脉）of the endometrium

14. Objectives of the uterus (proliferative phase)
Identify this organ
3 layers: endometrium, myometrium and perimetrium
Tubular glands
Coiled arteries

15. Endometrium of uterus in the secretory phase
Dilated glands with numerous secretion
Coiled arteries

16. Coiled arteries

17. Uterus

body
Endometrium
Myometrium
Perimetrium
cervix

18. Cervix
Endometrium
Myometrium
Perimetrium

19. Endometrium:epi+lamina propria
Epi:simple columnar epi stratified squamous epi.
Lamina propria: CT + cervical glands

20. Mammary glands Inactive Active Tubular-alveolar gland
DCT, adipose tissue

21. Inactive mammary gland
Fewer glands and ducts
Much CT and adipose tissue

22. Active mammary gland Relatively more glands and ducts
Less CT and adipose tissue

23. Active mammary gland
