Repro vesicles Flashcards
What two branches of the aorta provide the main blood supply to the reproductive organs

- internal iliac artery
Arterial supply of the Bladder, (inferior also-seminal gland, and prostate in males)
Superior & inferior vesical artery
-> branch of the internal iliac artery
Arterial supply of the Cervix, vagina, uterine tube & round ligament
Uterine artery (branch of the internal iliac artery)
(also vaginal artery for vagina; branch of internal iliac)
Arterial supply of the testes, perirenal fat, ureter & iliac lymph nodes
Testicular artery (L2)- branch of the abdominal aorta
Arterial supply of the uterus, ovaries, ureter, skin of labia & inguinal region
Ovarian artery (L2)- branch of the abdominal aorta
The arterial blood supply of the uterus comes from three arteries: the uterine branch of the ovarian artery, the uterine artery of the external iliac artery, and the uterine branch of the urogenital artery. All arteries enter the uterus at its mesometrial border and divide into smaller ones.
Arterial supply of the sigmoid colon, rectum & anal canal
Superior rectal artery
What is the superior rectal artery a branch of
Inferior mesenteric artery
Arterial supply of the anal skin & musculature and skin of buttock
Middle and inferior rectal artery
What is the arterial supply to the Vagina, fundus of bladder, bulb of vestibule, part of rectum
Vaginal artery
What is the vaginal artery a branch of
Internal iliac artery
What is the main arterial supply to the perineum?
Internal pudendal artery
What is the internal pudendal artery a branch of?
Internal iliac artery
What is the arterial supply to the pelvic muscles and hip joint?
Obturator artery
What is the obturator artery a branch of?
Internal iliac artery
What is the venous drainaige of the upper 1/3 of the rectum?
Superior rectal vein, draining into the inferior mesenteric and portal vein
What is the venous drainage of the lower 2/3 of the rectum?
Into the systemic venous system
At what vertebral level does the common iliac artery split?
L5-S1
Where does the internal iliac artery split & what does it split into?
Situated medially to the external iliac vein and obturator nerve.
At the superior border of the greater sciatic foramen, it divides into anterior and posterior trunks.
In which ligament is the ovarian artery contained?
Suspensory ligament of the ovary
In which ligament is the uterine artery and vein contained?
Cardinal/transverse cervical ligament
What artery does the ovarian artery anastomose with
Uterine artery
At what level does the uterine artery cross the ureter
The level of the ischial spine, junction of cervix and lateral part of fornix of vagina.
WHat is testicular torsion?
Testicular torsion is a surgical emergency, where the spermatic cord twists upon itself. This can lead to strangulation of the testicular artery, resulting in necrosis of the testis.
What arteries are found in the spermatic cord
Testicular artery
Cremasteric artery and vein
Artery to ductus deferens
What does the genital branch of the genitofemoral nerve supply?
The genital branch of the genitofemoral nerve enters the inguinal canal via the deep inguinal ring.
Males - scrotal skin and cremaster muscle. **
Females (accompanied by the round ligament of the uterus) supplies sensation to the labia majora and mons pubis**
What nerve is found in the spermatic cord?
Genital branch of the genitofemoral nerve
What is the arteriel supply to the vulva?
(inc: 1. Mons pubis 2. Labia majora 3. Labia minora
- Vestibule 5. Bartholin’s glands 6. Clitoris)
Internal peudendal artery
Where do the veins surrounding the prostate drain?
Veins surrounding prostate form the prostatic venous plexus which drains into the internal iliac vein
What is the inferior rectal artery a branch of
Internal peudendal artery
What is the superior rectal artery a branch of?
Inferior mesenteric artery
What is the middle rectal artery a branch of?
Internal iliac artery (anterior division)
With which venous plexus does the prostatic venous plexus communicate with on its posterior side?
Internal vertebral venous plexus
What veins drain into the external iliac vein?
Femoral vein
Inferior epigastric
Deep circumflex iliac veins
What veins drain into the internal iliac vein?
Superior and inferior gluteal vein
Internal pudendal vein
Obturator, lateral sacral, middle rectal, vesical, uterine, and vaginal veins
What structure (ligament) does the umbilical vein persist as in adult?
Round ligament
What is the function of umbilical veins in the foetal circulation?
Carries newly oxygenated and nutrient rich blood back to the fetus
into which vessels do the ovarian veins drain?
Left: left renal vein
Right: inferior vena cava
What vein is contained in the…
1. suspensory ligament
2. cardinal ligament
- ovarian vein
- Uterine vein
What vein is contained in the spermatic cord
cremasteric vein & papniform plexus of testicular veins
What is the venous drainage of the testes
Papmniform plexus
What is the function of the papniform plexus
venous return and temperature regulation of the testes..
Into which vein does the testicular vein drain?
The right testicular vein drains into ..inferior vena cava..
The left testicular vein drains into …left renal vein..
A varicocele is a pathology specifically to the venous drainage of the testis
What is varicocele?
When the pampiniform plexus of veins become dilated
Name the main cause of a varicocele
… Varicoceles may result from defective valves in the testicular vein, but kidney or renal vein problems can also result in distension of the pampiniform veins
WHat is testicular torsion?
Testicular torsion is a surgical emergency, where the spermatic cord twists upon itself. This can lead to strangulation of the testicular artery, resulting in necrosis of the testis.
What artery does the ovarian artery anastomose with?
The uterine artery
What is the venous drainage of the breast?
Corresponds with the arteries
- drains into the axillary, internal thoracic veins, lateral thoracic veins and second to fourth intercostal veins
Arterial supply of the lateral breast
- lateral thoracic artery
- intercostal arteries
- both branches of the axillary artery
Lateral thoracic artery
serves lateral chest wall
- branch of axillary artery
Intercostal arteries
Supplies blood to the rib muscles in the chest wall; consists of ten pairs.
- branches of internal thoracic arteries
Venous drainage & arterial supply of the penis
Deep dorsal penile veins and arteries
Venous drainage of testes
Papniform plexus
