The Female Reproductive System Ovary (No.41) Uterus in the proliferative phase (No.43) Uterus in the secretory phase (No.44) Cervix (No.45) Mammary gland (No.46) Jun Zhou School of Medicine, Zhejiang University

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

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

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

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

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

Follicular atresia （闭锁卵泡） Residual refractile zona pellucide

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

Uterus in the proliferative phase endometrium myometrium perimetrium

endometrium myometrium

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

Tubular glands

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

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

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

Coiled arteries

Uterus fundus body Endometrium Myometrium Perimetrium cervix

Cervix Endometrium Myometrium Perimetrium

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

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

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

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

Active mammary gland
