SDR L7 - Anatomy of the Pelvis II Flashcards
1) Internal Iliac
2) Internal Iliac
For both male and female bladders the arterial supply is from the vesicular branches of the (1) arteries and lymphatic drainage travels to the (2) nodes
T
(T/F) The bladder is an abdominal organ for infants, but for adults it has descended into the pelvis
1) Peritoneum/Body of Cervix
2) Pubic Bone
3) Cervix/Vagina
4) Urethra
The female bladder is bounded superiorly by the (1) and (1), anteriorly by the (2), posteriorly by the (3), and interiorly by the (4)
F (partially perineal and partially a pelvic structure)
(T/F) The urethra is partially a completely pelvic structure
1) Peritoneum/Sigmoid Colon
2) Pubic Bone
3) Rectum/Vas Deferens/Seminiferous Vessels
4) Prostate/Urethra
The male bladder is bounded superiorly by the (1) and (1), anteriorly by the (2), posteriorly by the (3), (3), and (3), and inferiorly by the (4) and (4)
1) Prostatic Urethra (~1.25 in)
2) Membranous urethra (~0.75 in)
3) Spong urethra (~6 in)
3 parts of the male urethra (proximal –> distal)
Spong
This part of the urethra passes beneath the pubic bone and is particularly susceptible to injury
Internal Sphincter Muscle
This structure prevents retrograde ejaculation of semen into the bladder, and there is no equivalent muscle in females
Prostatic Urethra
The 2 ejaculatory ducts and 15-20 prostatic ducts enter into this portion of the male urethra
TURP (Transurethral Resection of the Prostate)
This procedure is commonly performed to remove blockages in the male urethra near the prostate
Cystocele
Hernia of the urinary bladder
T
(T/F) During a TURP procedure the prostatic urethra gets resected and a new urethra forms around the inserted catheter
Suprapubic Cystotomy
If a patient cannot empty his or her bladder and catheterization is not an option, a (1) can be performed
F (Expansion of bladder lifts the perineum out of the way)
(T/F) Suprapubic Cystotomies can be performed with a low risk of peritoneal infection because the double fold in the perineum drains directly to aortic lymph nodes
T
(T/F) The vagina is considered both a pelvic organ and a perineal organ
Anterior, posterior, and two lateral
fornices
These are recesses that continuously surround the
cervix
Urethra
In females, this structure is considered embedded in the anterior vaginal wall
Uterus
Prolapse of this structure is common if the loose connective tissue between the rectum and vagina is
damaged
Pouch of Douglas
This peritoneal area is adajent to the upper ¼ of the posterior vaginal wall and it can be accessed via the posterior fornix
