Internal Genital Organs
Ovary
– Inner Structures
○ Tunica Albuginea (tunica albuginea ovarii)
○ Ovarian Cortex (cortex ovarii)
○ Ovarian medulla (medulla ovarii)
○ Follicules
– External Structures
○ Mesovarian border (margo mesovaricus)
○ Free Border (margo liber)
○ Tubal Extremity (extremitas tubaria)
○ Uterine extremity (extremitas uterina)
○ Medial Surface (facies medialis)
○ Lateral Surface (facies lateralis)
– Fixation of the Ovary
○ Ligament of Ovary (ligamentum ovarii proprium)
○ Suspensory ligament of ovary (ligamentum suspensorium ovarii)
○ Mesovarium
Growth and Maturation of Follicules:
– Primordial Follicule
○ Contain primary oocyte
○ Single layer of follicular cells
– Primary Follicules (after puberty, FSH)
○ Granulosa Cells
– Secondary Follicle
○ Primary Oocyte
○ Zona Pellicida
○ Granulosa Cells
○ Follicular Fluid
○ Produce Estrogen
○ Antrum
○ Theca Folliculi
– Graafian Follicle / Tertiary Follicle
– Secondary oocyte. Ovulation
– Corpus Luteum
– Corpus Albicans
Uterine Tube (tuba uterina)
– Parts of uterine tube:
○ Infundibulum (infundibulum tubae uterinae)
§ Abdominal Ostium (ostium abdominale)
§ Fimbriae (fimbriae tubae uterina)
§ Ovarian Fimbria (fimbria ovarica)
○ Ampulla (ampulla tubae uterinae)
○ Isthmus (isthmus tubae uterinae)
○ Uterine Part (pars uterina)
§ Uterine ostium (ostium uterinum)
– Walls of Uterine tube:
○ Tunica Mucosa
○ Tunica Muscularis
○ Tunica Serosa
○ Mesosalpinx
Uterus
– Parts:
○ Positioned in anteflexion
○ Fundus of uterus (fundus uteri)
○ Body of Uterus (corpus uteri)
○ Intestinal (posterior) surface (facies intestinalis)
○ Vesical (anterior) surface
○ Border of uterus (margo uteri)
○ Cervix of uterus
Supravaginal part (portio supravaginalis cervicis)
Vaginal Part
○ Uterine horn
○ Uterine cavity
○ The uterine opening of the oviduct (ostium uterinum tubae uternae)
○ Cervical Canal (canalis cervicis
○ External os of uterus (ostium uteri)
§ Anterior lip of cervix (labium anterius)
§ Posterior lip of cervix (labium posterius)
§ Nullipara: small and round opening
§ Primipara/multipara: narrow fissure
– Internal Structures (histology):
○ Endometrium
§ Functional Layer (stratum functionalis)
□ Simple columnar epithelium
□ Endometrium Stroma
□ Uterine Glands
§ Basal Layer (stratum basalis)
○ Myometrium
§ Longitudinal bundles of smooth muscle
§ Middle layer (stratum vasculare)
§ Arcuate Arteries
§ Radial Arteries
§ Straight arteries and Spiral arteries
○ Perimetrium
– Fixation of the Uterus
○ Peritoneal Folds
§ Broad Ligament of Uterus (ligamentum latum uteri) formed by peritoneum
– Mesovarium
– Mesosalpinx
– Mesometrium
○ Parametrial Ligments
§ Cardinal ligament of uterus (ligamentum cardinale uteri)
§ Vesico-uterine ligament (ligamentum vesicouterinum)
§ Pubocervical ligament (ligamentum pubocervicale)
§ Uterosacral ligaments (ligamenta sacrouterina)
§ Recto-uterine ligament (ligamentum rectouterinum)
§ Round ligament of uterus (ligamentum teres uteri)
○ Supporting apparatus of uterus
§ Perineal Muscles
§ Levator Ani Muscle (musculus levator anii)
Vagina (vagina)
– Vagina Orifice (ostium vaginae)
– Vestibule (vestibulum vaginae)
– Vaginal Canal (canalis vaginalis)
– Anterior wall (paries anterior)
– Posterior wall (paries posterior)
– Vaginal Fornix (fornix vaginae)
○ Anterior part (pars anterior)
○ Posterior aprt (pars posterior)
○ Lateral parts
– Hymen
○ Clinical significance: imperforated hymen may require medical intervention
– Urethrovaginal septum (Septum Urethrovaginale)
– Rectovaginal septum (septum rectovaginale)
– Recto-uterine pouch / Pouch of douglas (excavatio rectouterina douglasi)
Vaginal Wall (histology):
– Mucosa
○ Forms transverse folds
○ Estrogen promotes storage of glycogen
– Muscularis
External Genital Organs:
– Vestibule
○ Lesser vestibular glands (glandulae vestibulares minores)
○ Greater vestibular glands / Bartolin’s glands (glandula vestibularis major bartholini). May form barthlin’s cyst
– Labia Minora (labia minora pudendi)
– Clitoris
○ Glans of clitoris (glans clitoridis)
○ Body of clitoris (corpus clitoridis)
○ Crura of clitoris (crura clitoridis)
○ Prepuce of clitoris (preputium of clitoridis)
– Bulb of vestibule (bulbus vestibuli)
– Labia Majora / outer lips (labio majora pudendi)
– Mons Pubis
