Q

Bladder

A

One way flap valve where ureters pass.

Ureteric orifices & internal urethral orifice are at angles to trigone

Ureteric orifices have detrusor m. around them

Neck of bladder prevents retrograde ejaculation of semen into bladder

Apex= attach by median umbilical lig

Base= seminal vesicles & rectum; uterus & vagina. Receives ureters.

Q

Female Internal

A

Uterus

  • hollow & muscular organ
  • pear shpaed
  • in lesser perlivs
  • perimetrium, myometirum & endometrium

Ovaries

  • almond shaped female endocrine glands
  • suspended by mesovarium
  • covered w/ tunica albuginea not w/ peritoneum
  • oocyte released into peritoneal cavity

Uterine Tubes

  • lie in narrow mesentery- mesosalpinx
  • has 4 parts: infundibulum; ampulla; isthmus; intramural

Vagina

  • sup end surrounds cervix
  • canal

Q

Procedures of Vagina

A

culdoscopy- inserted through vagina post to examine ovaries/uterine tubes

Couldocentesis- to remove pelvic abscess, fluid or blood in retrouterine pouch

20
Q

Pelvic Ligaments

A
21
Q

Pelvis Ligaments

A

Broad lig- double layer of peritoneaum extends from sides of uterus to lat walls

  • mesovarium (ovary)
  • messalpinx (covers uterine tube)
  • mesometrium (part of broad lig)

Ovarian lig- medial pole of ovary to uterus

Transverse cervical- pelvic fascia from cervix & vagina to pelvic walls. Mackenrodt’s

Also suspensory lig & round lig!

22
Q

Important Uteral structures

A
  • lig teres- attach to uterus & below fallopian tube
  • plica rectouterina- fold of peritoneaum w/ rectouterine m. pass from sacrum to base of broad ligament!
  • Parametrium- of cervis to braod ligaments. Contains uterine a. & ovarian lig.
