Q

What are the positions of the uterus

A

1: anteflexion:
- Bends forwards between the cervix and body
- Most common

2: Antevertion
- Anterior inclination of the whole uterus on vagina
- i.e. bent beween vagina and cervix
- no problems but uncomfortable

3: Retrovertion
- Posterior inclination of whole uterus on vagina
- Disturbs sigmoid colon

A

Ovarian Fossa

Attached to broad ligament by mesovarium

Attached to lateral pelvic wall by suspensory ligament

30
Q

What are the boundaries of the Ovarian Fossa

A

superiorly:
- external iliac artery and vein

anteriorly and inferiorly:
- broad ligament of the uterus

posteriorly:
- ureter,
- internal iliac artery and vein

inferiorly:
- obturator nerve, artery and vein

31
Q

What is the arterial supply of the ovaries

A

Ovarian and Tubal branches of:

-Ovarian A (br. of Abdominal Aorta)

32
Q

What is the venous drainage of the ovaries

A

Pampiniform plexus:

  • drains into IVC on Right
  • drains into Lt. renal vein on Left
33
Q

What are the sites of ectopic pregancies

A 
Uterine Tube (most common)
Ovarian (rare)
Abdominal wall (peritoneal - very rare)
34
Q

What does the vagina communicate with both superiorly and inferiorly

A

Superiorly - uterus

Inferiorly - vestibule

35
Q

Where are the fornices

A

Area around the cervix has anterior, deep, posterior and lateral fornices

36
Q

What are the relations of the vagina?

A

Upper Portion:

  • Anterior:
  • –Cervix
  • –Base of bladder
  • –Ureters
  • –Urethra
  • Posterior
  • –Rectovaginal septum
  • –Rectouterine pouch
  • –Ampulla of rectum
  • Lateral
  • –Lateral fornices
  • –Ureters
  • –Uterine vessels

Lower Portion:

  • Levator ani
  • Greater vestibular glands
  • Bulb of vestibule
37
Q

What is the arterial supply of the vagina

A

Superior Part:
-uterine arteries

Middle part:
-vaginal arteries

Lower part:

  • Middle rectal arteries
  • Internal pudendal arteries
38
Q

What is the venous drainage of the vagina

A

Uterine venous plexus (drains to Internal Iliac vein)

39
Q

What is the innervation of the vagina

A

Upper portion is the same as the uterus :::
Inferior Hypogastric Plexus (Uterovaginal Plexus

Sympathetic:
-Lower lumbar segments (Lumbar Splanchnic Nerves)

Parasympathetic:
- S2-S4

See Diagram

Lower Portion:
-Only Somatic innervation. Therefore, -pudendal nerve
No parasympathetic supply

40
Q

What are the possible clinical associations with the uterus

A

Uterine prolapse:

pelvic floor muscles and ligaments stretch and weaken and no longer provide enough support for the uterus. As a result, the uterus slips down into or protrudes out of the vagina.

Fecal incontinence:

Fecal incontinence is one of the symptoms that may occur with pelvic organ prolapse
