ER 10+11+DLA Flashcards
urogenital triangle
lateral: ischiopubic ramus
base (posterior): line between ischial tuberosities
apex (anterior): pubic symphysis
Roof: levator ani
The rectouterine pouch (of Douglas)
The lowest point in the abdominopelvic cavity in an upright position
Culdocentesis?
checks for abnormal fluid in the rectouterine pouch
where does the uterine fundus, ovaries, and uterine tubes lymphatics drain?
lumbar nodes
body of uterus, cervix, and upper vagina lymph drain??
external and internal iliac nodes
BUT more internal iliac!
where does the lower vagina lymph drain?
superficial inguinal
what organ(s) drain into the lumbar nodes in the male?
testes
where does the lymph from the prostate, seminal vesicles, ductus deferens drain?
internal iliac nodes
what is the pelvic pain line?
above the PPL? below the PPL?
PPL = corresponds to the lower limit of the peritoneum
Below:
pain travels by parasympathetic by inferior hypogastric plexus
pain is referred to S2-S4
above:
pain travels by the sympathetic by the inferior hypogastric plexus
pain is referred to the T10-L2
venous drainage of the perineum?
deep dorsal vein (penis +clit)
internal pudendal vein (post. labial + scrotal)
external pudendal vein (anterior scrotum + labia majora)
lymph drainage of the erectile tissues?
deep inguinal nodes
Pudendal canal syndrome?
Compression of the pudendal nerve
burning sensation or numbness
failure of the dorsal nerve?
bulbospongiosus muscle?
dorsal: loss of sensation at head of penis and clit
muscle: failure to ejaculate
bloos supply of the prostate?
inferior vesicle A.
prostatic cancer metastasis
cancer cells can spread by the internal venous plexus since it is connected to the prostatic plexus
may have back pain due to spinal damage
Ischiocavernosus muscle and Bulbospongiosus muscle do what?
assist with expulsion of semen
what are the erectile tissues surrounded by?
what is that surrounded by?
tunica albuginea
then the buck’s fascia
anterior ureteral injury?
common in straddle injuries (between the legs)
will lead to urine and blood to leak out into the surrounding tissues
may not tear into buck’s facia
With injury to Buck’s fascia Extravasation will extend
into the superficial perineal pouch
posterior ureteral injury?
may occur due to straddle injury or direct blow to the groin
blood will leak from the urethral orifice and pain
role of cavernous arteries?
innervation?
priapism?
dilation of the helicine arteries and allow filling of blood
parasympathetic
priapism = prolonged blood pooling
emission phase?
expulsion phase?
emission:
sympathetic innervation
inferior hypogastric plexus
expulsion:
pudendal nerve
muscle contractions from bulbo + ischio
