bounded by the bones of the pelvis. Its oblique
roof is the pelvic inlet (the superior opening of the
pelvis). Its lower boundary is the pelvic floor.
Location:
The pelvic cavity is a bowl-like structure that sits
below the abdominal cavity.

5. Types of Pelvis
1. Gynecoid
2. Android
3. Anthropoid
4. platypelloid

7. Organs in Pelvic cavity
• Urinary Bladder
• Prostate in male
• Ovaries in female
• Cervix in female
• Testes in male
• Penis in male
• Colon and anus
• Distal end of large intestine

8. URINARY BLADDER
It is located within the pelvis in back of symphsis
pubi .
FEMALES
Vaginal artery supplies the posterio inferior
portion of the Bladder.
MALES
Inferior vesicular artery supplies the posterio
inferior portion of Bladder

10. RECTUM
• It begins superior to level of third sacral vertebrae
and extend from sigmoid colon to puborectalis
muscle.
• It consists of coverings of peritoneal and flexures .

12. ANAL CANAL
• It starts from puborectalis.
• Ends at anus.
• There is a transition from simple columnar epithelium
of the gut to stratified squamous epithelium of the
epidermis.
• Two sphincters.
• Intenal involuntary.
• External voluntary.

14. REPRODUCTIVE ORGANS EMBRIOLOGY
Males
• Testes are primary sex organs.
• Vas deferens and epididymis are formed.
• From the mesonephric ducts.
Females
• Ovaries are primary sex organs
• Uterine tubes and uterus are derived.
• From paramesonephric ducts.

15. OVARIES
• Almond shaped and oval bodies which produce ova.
• Three ligaments of the ovary .
• Suspensory.
• Ligament of the ovary .
• Mesovarium.

17. UTERUS
• Pear shaped muscular organ between bladder
and rectum.
• Uterus consists of:
Fundus
Body
Isthmus
cervix

18. UTERINE TUBES
• Consists of oviducts and there is no direct connection to ovary.
• Oviducts open into peritoneal cavity and medially into the
uterus.
• It consists of:
Isthmus
 ampulla
infundibulum

20. UTERINE TUBES
• Consists of oviducts and there is no direct connection to ovary.
• Oviducts open into peritoneal cavity and medially into the
uterus.
• It consists of:
Isthmus
 ampulla
infundibulum

21. VAGINA
• It is formed from urogential sinus.
• Extend from cervix of uterus to the vestibule of the vagina
• This organ passes through the urogential diaphragm and the
pelvic diaphragm.

22. DUCTUS DEFRENS
• It conducts sperms from epididymis through inguinal ligament
to posterior surface of the bladder.
• Seminal vesicles are present at posterior surface of bladder
superior to prostate
• , does not store sperm but contribute to semen.

24. PROSTATE
• Largest accessory gland of the reproductive system.
• The function of prostate is to secrete an appearance ,which
constitute 50-75% of volume of semen along with semen and
seminal vesicle fluid.
