Female Reproduc6ve System
• Gonads = ovaries – almond shaped – flank the uterus on either side
– a?ached to the uterus and body wall by ligaments
• Gametes = oocytes – released from the ovary during ovula6on
– Develop within ovarian follicles

Ligaments
• Broad ligament – A?aches to walls and floor of
pelvic cavity
– Con6nuous with parietal peritoneum
• Round ligament – Perpendicular to broad ligament
• Ovarian ligament – Lateral surface of uterus ‐ ‐>
medial surface of ovary
• Suspensory ligament – Lateral surface of ovary ‐ ‐> pelvic
wall

Ovarian Follicles
• Layers of epithelial cells surrounding ova • Primordial follicle
– most immature of follicles
• Primary follicle – single layer of follicular (granulosa) cells
• Secondary – more than one layer and growing cavi6es
• Graafian – Fluid filled antrum – ovum supported by many layers of follicular cells
– Ovum surrounded by corona radiata

Ovarian Follicles
![Page 6: FEMALE REPRODUCTIVE SYSTEMfaculty.mtsac.edu/mpresch/35_lecture_files_unit_3/13 Anat...Female Reproducve System • Gonads = ovaries – almond shaped – flank the uterus on either](https://reader033.vdocuments.us/reader033/viewer/2022042601/5fb026909adc931afc6d5fda/html5/thumbnails/6.jpg)
Corpus Luteum
• Ovula6on releases the oocyte with the corona radiata
• Leaves behind the rest of the Graafian follicle • Follicle becomes corpus luteum
• Con6nues to secrete hormones to support possible pregnancy un6l placenta becomes secretory or no implanta6on
• Becomes corpus albicans when no longer func6onal

Corpus Luteum and Corpus Albicans

Uterine (Fallopian) Tubes
• Ciliated tubes – Passage of the ovum to the uterus and
– Passage of sperm toward the ovum
• Fimbriae – finger like projec6ons that cover the ovary and sway, drawing the ovum inside aRer ovula6on

The Uterus
• Muscular, hollow organ – supports the embryo/fetus during pregnancy
• Three layers – Endometrium
• inner lining of columnar epithelium
• highly modified during pregnancy
– Myometrium • smooth muscle layer
– Perimetrium • adven66a of the uterus

The Uterus
• Fundus – superior most area
• Body – longest part of the uterus
• Cervix – necklike region of the uterus that extends into the vagina
– internal and external os are the openings of the cervix

The Vagina
• Birth canal – thin walled expandable tube
– posterior to the urethra and anterior to the rectum
– folded with rugae • Hymen
– vascular covering to the vagina

External Genitalia • Labia – Folds that protect the ves6bule
• Major – dry skin with hair
• Minor – moist mucus membrane
• Clitoris – homolog to the glans penis
• contains erec6le 6ssue, a glans, body and prepuce • Perineum – diamond shaped region containing the urethral orifice, external genitalia, and anus.
