Female reproducve system & utrine tube posion of uterus [email protected] v Rectouterine (Douglas) pouch: Reflecon of from rectum to upper part of posterior surface of v Uterovesical (vesicouterine) pouch: Reflecon of peritoneum from uterus to upper surface of urinary bladder v Broad of uterus: Extension of peritoneum from lateral wall of uterus to lateral wall of , encloses the uterine tubes Ø It is an almond-shaped organ. Ø It is aached to the back of the broad ligament by a peritoneal fold () Ø Its medial end is aached to uterus by ligament of . Ø Its lateral end is related to the fimbriae of the uterine tube.

² It is 10 cm long. ² It is enclosed in the broad ligament of uterus.

It is divided into: Intramural part opening into the uterine wall Isthmus narrowest part Ampulla widest part (site of ferlizaon) Infundibulum funnel-shaped end, has finger-like processes (fimbriae), related to ovary A hollow, pear-shaped muscular organ ,Divided into: Fundus - no cavity - The part of uterus above the level of uterine tubes. Body - cavity is triangular - The part of uterus from the level of uterine tube to the level of the isthmus of uterus. * Cervix - cavity is fusiform ** divided into: - The part of uterus below the level of the *Supravaginal isthmus of the uterus. **Vaginal

RELATIONS OF UTERUS FUNDUS + BODY + Anterior: superior surface of SUPRAVAGINAL PART urinary bladder OF CERVIX Posterior: sigmoid colon Lateral: uterine VAGINAL PART OF Anterior: anterior fornix of CERVIX vagina (surrounded by vaginal Posterior: posterior fornix of fornices) vagina Lateral: lateral fornices of vagina • INTERNAL OS: opening between cavity of body of uterus & cavity of cervix ()

• EXTERNAL OS: opening between cervical canal & cavity of vagina • In a nulliparous woman: external os appears circular. • In a mulparous woman: external os appears as a transverse slit with an anterior & a posterior lip.

Nulliparous: Never having given birth to a child. Mulparous: having borne more than one child. Nulliparous Mulparous u OVARIES: PRIMARY SEX ORGANS IN FEMALE 1) Producon of female germ cells 2) Secreon of female sex hormones u UTERINE TUBES: 1) Site of ferlizaon 2) Transport of ferlized ovum into the uterus

u Funcon of The Uterus it is responsible for the development of the embryo and fetus during .

Long axis of whole uterus is bent ANTEVERTED UTERUS forward on long axis of vagina

Long axis of body of uterus is bent ANTEFLEXED UTERUS forward on long axis of cervix

RETROVERTED UTERUS Fundus & body of uterus are bent backward on the vagina and lie in recto - uterine pouch.

Long axis of body of uterus is bent RETROFLEXED UTERUS backward on long axis of cervix

ANTEVERTED ANTEFLEXED UTERUS USUAL POSITION OF UTERUS 1) at juncon between fundus & body of uterus 2)Ligaments of cervix : (At the level of uterine tube) (1) Round ligament of uterus: Extend from cervix to: Extends through • anterior (pubocervical) . to labium majus (external genitalia). • lateral (transverse cervical or (lies anterior to the uterine tube) cardinal) . (2) Ligament of ovary: • posterior (uterosacral or B/t ovary & uterus (lies posterior to the uterine tube) sacrocervical) . • pelvic walls
