Exam #4: Pelvis II Flashcards
Describe the path of sperm from the testes to bulbouretheral gland.
- Testes
- Epididymis
- Ductus Deferens
- Seminal vesiculus/ Ejaculatory duct
- Prostate
- Bulbouretheral gland
What volume of fluid do the seminal colliculus, prostate, and bulbouretheral glands contribute?
Seminal colliculus= 60%
Prostate= 20%
Bulbouretheral Gland= 10%
What two structures form the ejaculatory duct?
Seminal colliculus & Ductus Deferens
What is BPH?
Benign Prostatic Hyperplasia (Hypertrophy)
- Occurs w/ aging
- Leads to swelling of a lobe of the prostate–>impingement of the urethera
- Sx= weak stream & urinary urgency
How is BPH treated?
TURP= Transurethral Resection of the Prostate
- Insert resectoscope w/ electrical loop on end
- Head removes part of prostate
What are the complications of TURP?
- Sperm reflux into bladder
- Urine dribbling/ incontinence
What is the difference in control of the external & internal uretheral sphincters?
External= voluntary Internal= involuntary
What is the difference between a space & a pouch?
Pouch is a potential space for the accumulation of fluid & infection
What is the Space of Retzius?
- Retropubic space behind pubis in males & females
- Functions to accomodate bladder distension
What is the retrorectal space?
- Space behind the rectum in males & females
- Functions to accomodate rectal expansion
What pouch is specific to males?
Rectovesical pouch
- Between bladder/prostate & rectum
What pouches are specific to females?
- Vesicouterine pouch
- Rectouterine pouch/ Pouch of Douglas
What is the Vesicouterine Pouch?
Anterior space between bladder & uterus
What is the Rectouterine Pouch?
Posterior space between uterus & rectum
Which pouch in females is easier to access if there is an infection?
Pouch of Douglas/ Rectouterine pouch
What does the external iliac artery continue into the lower limb as?
Femoral artery
What does the internal iliac artery bifurcate into?
Anterior & Posterior Divisions of the Internal Iliac Artery
What are the branches of the posterior division of the internal iliac artery?
1) Iliolumbar–> lumbar spine
2) Lateral sacral–> sacrum
3) Superior gluteal
Where does the superior gluteal artery typically pass?
Between L5 & S1 nerves
What are the branches of the anterior division of the internal iliac artery?
Anteriorly=
- Obturator
- Umbilical
Posteriorly=
- Inferior Gluteal
- Internal Pudendal–>Perineum
Middle=
- Uterine
- Inferior Vesicular
- Middle Rectal
What is the branch of the umbilical artery?
Superior vesicular (bladder)
What nerves does the inferior gluteal artery pass through?
S1 & S2
What is the branch of the uterine artery?
Vaginal
Lumbosacral Trunk
L4-5
