|
|
what is a cause of enterocele?
|
weak palvic ligaments, obesity, weak pelvic floor

what is menorrhagia?
dysmenorrhea? |
menorrhagia- heavy bleeding during periods
dysmenorrhea- painful menstruation |
|
can fibroids cause dysmenrrhea? why?

YES! you are contracting with a big lump in your muscle- that would be painful anywhere
|
|
what are some urinary sx that uterine fibroids can cause? why/how?
|
frequency and urgency if they are large enough to put pressure on the bladder.
retention if they are enough to block the bladder |
|
what are intrauterine polyps like histolgically?
|
they grow out of the endometrium and into the uterine cavity
|

|
same reason as colonic polyps do.
also remember the endometrium is very highly vascularized |

|
endometrioma or chocolate cyst- when blood accumulates under the ovarian capsule
|

can you leave an endometrioma alone? why?
|
NO! the blood has nowhere to drain so it will eventually burst all over the pelvic cavity

wha does it look liek? |
|
|
sx of adenomyosis?
how are these complications different than other locations of endometriosis? |
you may get dysmenorrhea and menorrhagia
no firbosis or adhesions because it is in the uterus |
|
what is the most common malignancy of the female reproductive tract. why do you think this is?
|
the endometrium is constantly growing and stuff. it is easier to slip up here.
|

a big dome
|
|
show the obtuatr internus
what does it attach to in the pelvis? |
the medial part of the obturator membrane at the pubic side of the opening
|
|
how does the obturator internus reach to the femur? what does it have to pass?
|
passes under the ischial spine and wraps around the same level back to the greater tuberosity
|
|
what do they meanby obturator internus vs externus?
|
which side of the obturator membrane they attach from
|
|
where are the other hip stabilizers in relation to the obturator internus?
gemelli and quadratus? |
they start more posteriorly so don't need to wrap around as much
|
|
what angle do the obturator forament form from the body? what direction do they face?
|
wide angle toward the back (back bowl)
|
|
show the obturator internus in relation to the pelvic cavit

anterior- membrane of obturator internus
posterior- coccygeal bone |
|
what is that hole in the frot of the levator ani? what does it do?
|
females- lets vagina and urethra pass
males- just urethra |
|
describe and show the 2 parts of the pubococcygeus
why are they considered the same muscle kinda? |
the main part connects the front pubic bone with the tailbone
the front one forms a sling around the urogenital hiatus they are still in a sheet |
|
what is that anterior parts of the pubococcygeus called in men vs women? function?
|
king of like a sling for either the prostate or the vagina
|
|
what ligament goes down the middle of the levator ani?
|
|
|
what are the intermediate fibers of the levator ani? why is it special?
|
the puborectalis- it doesn't connect to the coccyx
|
|
show the posterior fibers and name them. levator ani
|
iliococcygeus
|
|
what is the attachment point of the levator ani to the obturator internus called?

|
bottom of pubic symphysis to ischial spine
|
|
where does the coccygeus insert? 2
in relation to the levator ani? |
from the edge of the levator ani tendonous arch at the ischial spine to...
the part of the coccyx above the levator ani |
|
what is the location and function of the perineal body?
|
it is at the posterior arch tip of the urogenital hiatus and functions to connect the pelvic diaphragm with the perineum
|
|
what are some of the great fiunctions of the pelvic floor in general?
the sling muscles? |
keeps out intestines and pee from falling out from the intraabdominal pressures (esp with sneezing)
thhe sking muscles also help to keep the rectum and vagina closed |
|
what nerve controls the levator ani?
spinal levels? mnemonic? |
S 2, 3, 4 keeps shats off the floor (puborectalis)
pudendal nerve |
|
show the coccygeus from the back
how long is it compared to the levator ani? how do you know? |
not as long because it only goes to the ischia spine which is the shortet any levator ani goes (not counting slings
|
|
difference between the rectal and urogenital slings?
|
one holds the rectum back
other holds the urethra/maybe vagina forward |
|
what nerve controls the coccygeus?
spinal levels? mnemonic? |
S 4,5 anterior rami
|
|
how do you remember the shats off the floor mnemonic only applies to levator ani?
|
because the coccygeus only forms the back wall of the pelvic diaphragm and doesn't have the same power to hold stuff inside your tubes
|
|
describe the oritation of the deep perineal pouch and perineal membrane in relation to the pelvic diaphragm?
|
the membrane is below it and the pouch is the space between
|
|
is the perineal membrane just a membrane?
what are it's attachments and shape? |
no, it is a muscle that attaches like a triangle to the front pubic arch, but stops at the ischial tuberosity and has a free edge
it also has orifices for anything urogenital to pass through |
|
how does the perineal membrane look different in males than females? 2
|
the angle would not be as wide and there would be no vaginal orifice
|
|
does the perineal membrane go up to the tip of the pubic arch?
|
no
|
|
what is in the pelvic diaphragm directly above the urethral and vaginal orifices for the perineal membrane?
|
the urogenital hiatus... so nothing
|
|
show what the uterus and bladder look like sitting in their places
where are they located relative to the pelvis? |
uterus is right at the pelvic brim peaking over our pubic crests and the bladder sits right behind the pubic symphysis
|
|
what is in the perineal pouch? space?
|
it is a collection of muscles
|
|
what innervates all the deep perineal puch muscles?
|
pudendal nerve
|
|
how much space in in the perineal pouch?
is it closed off? how? |
not much space and it is open in the fromt and back because the perineal membrane leaves those spaces
|
|
how is the perineal membrane angled?
how much of it would you see if you looked straight down at it? |
very steeply angled toward the front
|
|
what does this perineal membrane angle explain about feamle anatomy?
|
why our urethra and vagina tend to face the front
(desbite our pubic symphysis being so low) |
|
where does the perineal body connect to the perineal membrane?
what does this mean for positioning? |
the perinela membrane ends where the urogenital hiatus ends
|
|
what are the 2 deep perineal muscles that men and women have in common?
|
|
|
function of the transverse perineal muscle?
|
to give additional support ot the perineal body
|
|
function of the external urethral sphincer? specific location in men vs women?
|
to close off urination voluntarily
men- membranous urethra women- pretty much at the urethral opening |
|
what 2 muscles are unique to women?
imagine them. |
|
|
function of the compressor urethrae?
|
aids with the external urethral sphincter to close off the urethral by compressing it
|
|
function of the sphincter urethrovaginalis??
|
forming a spnicter to help close the vagina and the urethra using the perineal body as an anchor
|
|
can I feel the sphincter urethrovaginalis on myself?
what is it's span? how do I know? |
yes- it is right around where the deep perineal pouch should be.
beyond that, I cannot constrict my vagina |
|
