FEMALE REPRODUCTIVE SYSTEM

HISTOLOGY

Female Reproductive System Consists of

Paired ovaries
Uterine tubes
Uterus
Vagina
External Genitalia

Female Reproductive Organs

Cortex

Medulla

Female Reproductive Organs

Ovary
Almond shaped (3 x 1.5 x 1 cm)
Produce Oocytes
Produce Hormones

Coverings of Ovary

Menarche & Menopause

Menarche
Menopause period
Postmenopausal period

Follicular Growth & Development

Follicular Growth & Development
Beginning in Puberty with the release of FSH
Group of Primordial Follicles each month begins a process of follicular growth

Follicular Growth & Development

This involves Growth of the oocyte
Proliferation & changes in the Follicular cells
Proliferation & differentiation of the Stromal Fibroblasts

Primordial Follicle

Unilaminar Primary Follicle

Microvilli of Oocyte & Filopodia of Granluosa cells

Microvilli

Filopodia
Granluosa cell

Microvilli of Oocyte & Filopodia of Granluosa cells

Primordial Follicle

Unilaminar Follicle
Multilayered Follicle
Primary Follicle

Multilaminar Primary Follicle

Antral Follicle

Antrum

Granulosa
Theca interna & Externa
Antral Follicle
Preovulatory Follicle

Follicular Development

Graafian Follicle

Stages of Ovarian Follicle

Zona Pellucida

Granluosa Cell
Ultrastructure of Primary Follicle & Zona Pellucida

Follicular Fluid

Large GAG hyaluronic acid
Growth factors
Plasminogen
Fibrinogen
Anticoagulant heparan sulfate proteoglycan
High concentrations of steroids

Wall of Antral Follicle

Antrum
Granulosa
Theca I
Theca E
Stroma

Apoptosis of G. cells

Atresia of Follicle(Apoptosis & Autolysis)

Hormonal Regulation of Ovarian Function

Corpus Luteum (yellowish body)

Granlosa lutein cell

Theca lutein cell
Corpus LuteumGranulosa cells Granulosa lutein cells Theca interna cells Theca lutein cells

Remnants of corpus luteum are phagocytosed by macrophages, after which fibroblasts invade the area and produce a scar of dense connective tissue called a corpus albicans (L., white body).

Corpus Albicans (white body)

Uterine Tubes & Uterus

Uterine Tubes

Ampulla
Isthmus
infundibulum
Intramural

Wall of the Oviduct:

Mucosa
Muscularis
Serosa

Cross Section in Oviduct (Ampulla)

Mucosa of the Uterine Tube Wall

Ciliated Cell& Secretory (Peg Cell)

The Epithelium Cell Types:
Ciliated Cells in which ciliary movements sweep fluid toward the uterus
Secretory Peg Cells, nonciliated & often darker staining, often with an apical bulge into the lumen, which secrete glycoproteins of a nutritive mucus film that covers the epithelium
