Female reproductive system 1. Genital organs 2. Functions 3. Ovary 4. Uterine tube 5. Uterus 6. Vagina 7. Mammary glands 8. Embryogenesis 9. Menstrual cycle

1. Internal genitalia (ovaries, uterine tube, uterus, vagina) 2. External genitalia (labia majora and minora, mons pubis, clitoris, vestibular bulbs) 3. Accessory organs (vestibular glands) 4. Mammary glands

Functions 1. Generative 2. Endocrine 3. Fertilization 4. Embryo and fetus development 5. Newborn nourishment

Ovary ( ovogenesis+endocrine)

Ovarial cortex (maturing follicles +atretic bodies+ corpora lutea+ corpora albicans)

Types of follicles

Primordial follicles

Primary follicle

Secondary follicle

Graafian follicle theca

Corpus luteum 1. Proliferation and vascularisation 2. Glandular metamorphosis 3. Secretion 4. Involution 5. Corpus albicans

Luteocytes

Types of luteocytes 1. Theca luteocytes 2. Granulosa luteocytes Function – synthesis of progesteron which regulates uterinal mucosa

Uterine tube mucosa ( epithelium+lamina propr.) muscular (O II sm. m.) serosa

Uterine tube (conveys oocytes, place of fertilization)

Uterine tube 1. Mucosa (ciliated epithelium+lamina propria) 2. Muscularis (O and II layers) 3. Serosa (peritoneum duplication) Secretory (peg) cells

Uterine tube epithelium

Uterus 1. Endometrium 2. Myometrium 3. Perimetrium 4. Parametrium Myometrium Endometrium Glands Space Epithelium Lamina propria Myometrium

Uterine glands

Endometrium layers: 1) functional (spongy and compact); 2) basal Uterine glands (crypts) - are simple tubular nonbranched glands Have neck, body and fundus Cambial cells lie in the bottom

Vagina

Mammary gland

Lactating mammary gland

Secretory process of lactating mammary gland

Embryonic development 1. Indifferent stage 3-6 th weeks 2-3 weeks-gonocytoblasts in yolk sack 4 week-migration to embryo 2. Different stage 8-10 w testes inhibin I 20 w rete testis inhibin II 40 w inhibin III Androgen masculinization

Endocrine regulation Higher center (preoptic zone)

Menstrual cycle Cyclic structural modifications in endometrium and other organs Menstrual 1-4 days Postmenstrual 5-14 days Premenstrual days

Uterine glands

Vagina and endomethrium
