Pelvic Organs II Flashcards
where is broad lig and round lig of uterus located
broad lig on post of uterus
Round lig of uterus runs ant to uterus and attaches on fat of pre pubic region
what type of organ is the overies
Extraperitoneal organ
how are the overies suspended in space (what are they connected to) (3)
To broad lig by mesovarium
to uterus by lig of overly
to pelvic wall by suspensory lig
What connects the overy to the uterine tube
ovarian fimbria
Is the uterine tube covered by peritoneum and what does it lie in
Completely surrounded by peritoneum + lies within upper part of broad lig (mesosalpinx)
where is the usual site of fertilization
ampulla of uterine tube
What is the blood supply of the mesovarium portion of the broad lig (2)
- Ovarian branch of uterine artery
2. terminal branch of uterine aa
What is the blood supply of the mesosalpinx of the broad lig (2)
- Branch of uterine artery
2. branch of ovarian aa
What is the sup part of the uterus called where the uterine horns attach
Fundus
What do the uterine horns attach to post and ant
post attach to lig of overy
Ant attach to round lig
What is the opening into the cervical canal called
external os (internal os separates cervix from uterus)
What is the site of insemination
Vaginal fornix (there are 4)
What are the layers of the uterus from out to in
perimetrium
myometrium (thickest)
Endometrium
What position is the uterus in relation to the vagina
Uterus is antverted and anti flexed
what lig keeps the uterus anteverted and antiflexed
round lig
What fails in a uterine prolapse
failure of supporting mechanisms of uterus (perineal and pelvis membranes)
What is the blood supply of the ovaries + branch
Ovarian aa (branch of abdominal aorta)
What supplies the uterus and branch its from
Uterine aa (branch of int iliac)
What branches does the uterine aa give off (3)
Vaginal aa, ovarian and tubar branch
What are the sites of ectopic pregnancy (6)
Ovarian Infundibuluar Tubal isthmus Abdominal Interstitial Cervical
what occurs in an isthmus tubal etopic preg
can develop for 3/4 moths but won’t stretch enough so it leads to rupture of uterine horm
What is the worst site of etopic preg
Interstitial
What aa supplies the pelvic organs (3)
Sup vesical aa
Inf vesical aa (base of bladder/prostate)
middle rectal aa (from post int iliac)
What is the main dif from male and female pelvic organ aa supply
Presence of uterine aa instead of inf vesical aa
Venous drainage of all pelvic organs has connection to these veins +clinical app of this)
Lateral sacral veins but they are valveless and blood can travel to int vert venous plexus (cancer metastasis)
what is the path of lymph drainage of pelvic organs
Int iliac
common iliac
aortic
chyli cistern
What is the main ganglion that inn the pelvic organs + what does it get its symp + parasympathetic from
Inf hypogastric nerve plexus
Sympathetic contribution from L1,2
Parasympathetic from pelvic splanchnic
Where would pain referral from pelvic organs refer to
sympathetic referral to L1,2 (groin)
Parasympathetic referral to S2,3,4 in back
