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
1) Internal Iliac
2) Uterine
Arterial supply to the vagina is supplied by the vaginal branch of the (1) artery and vaginal branch of the (2) artery
E) Urethra
Which of the following structures does not pass laterally to the vagina? A) Ovaries B) Ischial Spine C) Uterine Tubules D) Ureters E) Urethra F) Uterine A.
1) Uterine A.
2) Ovarian A.
Aterial supply to the uterus is through these two arteries
1) Para-aortic
2) Internal Iliac
3) Superficial Inguinal
Lymphatic drainage from the uterus can be to
three locations. Superiorly to the (1) nodes, but also to the (2) and (3) nodes
Uterovesicular
Anteriorly the peritoneal recess is called the (1) pouch, and posteriorly it is called the pouch of Douglas
Broad Ligament
This structure is a fold of peritoneum draped over the uterus connecting the lateral sides of the uterus to the side walls of the pelvis
Round Ligaments
These ligaments pass from the side wall of the uterus through the inguinal canal to the labia majora
1) Cardinal L. (Cervix –> Side wall of pelvis)
2) Uterosacral L. (Cervix –> Sacrum)
3) Pubocervical Fascia (Cervix –> Pubic Bone)
These 3 connective tissues support the cervix at the base of the uterus
Intramural
This portion of the uterine tubes is within the wall of the uterus
Salpingitis
Inflammation of the fallopian tubes; can result in infertility
Hysterosalpingogram
Patency of uterine tubes is determined with a
Unicornuate uterus
Congenital malformation of the uterus that results in a uterus with one horn
1) Uterine
2) Ovarian
Arterial supply for the uterine tubes comes from the (1) and (2) arteries
1) Internal Iliac
2) Para-aortic
Lymphatic drainage for the uterine tubes travels to the (1) and (2) lymph nodes.
1) Suspensory Ligament of the Ovary (infundibulo-pelvic ligament)
Arterial supply to the ovary is via the ovarian artery (duh), which travels to the ovary within the
1) IVC
2) Left Renal V.
3) Para-aortic
The right ovarian vein dumps into the (1), while
the left ovarian vein dumps into the (2). Lymphatic drainage travels to the para-aortic nodes
T
(T/F) Ovaries shrink in size after menopause and are irreversibly carried superiorly in the broad ligament during pregnancies
1) upper 2/3 of vagina
2) most of uterus
3) bladder
4) urethra
These 4 parts of the female anatomy drain to the Iliac Nodes
1) lower 1/3 of vagina
2) part of upper uterus via round ligament
3) urethra
These 3 parts of the female anatomy drain to the Superficial Inguinal Nodes
1) fundus of uterus
2) ovaries
3) uterine tubes
These 3 parts of the female anatomy drain to the Para-aortic Nodes
1) Bladder
2) UGD
3) Pubic Bone
4) Rectum
The prostate is surrounded superiorly by the (1), inferiorly by the (2), anteriorly by the (3), and posteriorly by the (4)
Benign Prostatic Hyperplasia
BPH =
Ureter
Prostate cancer can eventually cause renal failure if
the this structure becomes invaded and impeded from the cancer
1) Internal Iliac
2) Internal Iliac
Arterial supply to the prostate is via the (1) artery and lymphatic drainage from the prostate travels to the (2) nodes
Vertebra
If cancer establishes metastasizes this structure, it can travel up into the skull because veins draining the region do not have any valves
Vas Deferens
This structure is a tube that leads from the testes to join with the prostatic urethra
Ductus Deferens
Vas Deferens aka
Seminal Vesicles
These structures are lobulated sacs found posterior to the bladder and prostate and anterior to the rectum. They secrete an alkaline fluid that composes semen (helps balance out acidic secretions in the vagina, so sperm can prosper)
Ejaculatory Duct
The vas deferens is called the (1) until it enters the prostatic urethra
Prostate and seminal vesicles
These two structures contribute most to the production of semen
