Posterior fornix

18
Q

What can be felt in the digital examination through the vagina?

A 
Ischial spine 
Ovaries 
Uterine artery pulse 
Cervix 
Sacral Promontory
19
Q

What are the main branches of the internal iliac artery that supply the pelvic viscera?

A

Superior Vesical Artery
Uterine Artery
Middle Rectal Artery

20
Q

Which branches supply the walls of the pelvis?

A

Sacral, Gluteal and Obturator Branches

21
Q

What artery supplies the perineum and the recto-anal region?

A

Pudendal Artery

22
Q

Where is there an arterial anastomosis in the pelvic region?

A

Ovarian artery and the uterine artery both supply the ovaries and they anastomose.

23
Q

What are the two divisions of the uterine artery?

A

Ascending Branch - supplies the uterus and ovary (along with the ovarian artery)
Descending Branch - Vaginal Artery (equivalent of inferior vesical in men) - supplies the vagina

24
Q

Where are eggs from the ovary initially released into?

A

Into the peritoneal cavity because the ovary is on the posterior surface of the broad ligament

25
Q

How is the bulbospongiosus different in women?

A

It splits into two around the vestibule of the vagina

26
Q

What makes up the body and glans of the clitoris?

A

Body - corpora cavernosae

Glans - corpus spongiosum

27
Q

Describe the arrangement of sphincters in the deep perineal pouch.

A

Part of the pelvic floor muscles form compressor urethrae (compresses the urethra)
Parts of the fibres from here combine with the external urethral sphincter to for sphincter urethrovaginalis.
It wraps around the urethra and keeps it closed.

31
Q

Para-aortic lymph nodes

32
Q

Where do the perineum and external genitalia drain to?

A
