Pelvic Vessels, Nerves, Lymph Flashcards
What are the parts of the uterus? (main parts)
fundus (farthest away from the opening of the uterus.
Body –> has uterine horns, which are where the uterine tubes make contact with the uterus
body tapers off and gets more narrow until you get to an “isthmus”
after that is “neck” –> which is called “cervix”!
How come you can see the cervix being larger than the body of the uterus?
what are the different
there are changes in uterine ratios..
body to cervic changes depending on the hormonal environment.
newborn (when under the influence of maternal hormones): 2:1
out of the hormonal environment before making your own: 1:1
puberty, making your own = 2:1
Having kids, you can get to as high as 3:1
then you are post menopause, where you stop making hormones, and back to 1:1
What are the spaces of the uterus?
uterine cavity
then we hit the isthmus, go through the “Internal Uterine Os”
then it goes through the cervical canal
then through the “External Uterine Os”
to know about the cervix and the vagina?
the cervix protrudes slightly to the uppermost part fo the vagina
this determines if the cervix is supravaginal or just vaginal
Layers of the uterus from deep to superficial?
outermost = perimetrium
uterine muscle itself = myometrium
inside = endometrium (sloughed off during the menstrual cycle)
Hysterectomy?
different varieties.. one where you take out the uterus but leave the cervix (partial)
ones where you take out the uterus and the whole cervix but leave the uterine tubes (Total)
one where you take everything including vagina and ovaries and uterine tubes = Radical hysterectomy
What are the ligamentous structures of the uterus? (5)
Broad L of the uterus = made of peritoneum (right up against the uterus is mesometrium, part against the ovary is mesovarium, part along uterine tube is mesosalpinx)
Suspensory L of the Ovary = layer of peritoneum wrapping around the ovarian blood vessels (comes from the aorta)
Suspensory L of the Uterus
Gubernaculum remnants –> 1) Round ligament of the uterus and 2) Ligament of the Ovary
Transverse Cervical L.
Gubernaculum and the ovary/uterus?
what becomes what?
the upper part of the gubernaculum is directly attached to the ovary (ligament of the ovary)
the lower part ends in the labia mejora (round ligament of the uterus)
What 3 things are coming from the lateral wall of the uterus?
1) goes to the deep inguinal ring = round ligament of the uterus
2) goes and ends in fimbrae = uterine tube
3) attached to the ovarian ligament, ending in ovary.. that’s the ovary
What is the transverse cervical L made of?
most specifically the middle lamina of the hypogastric sheath, which is made of condensed endopelvic fascia
Uterosacral L?
made of parietal membranous pelvic fascia
it’s part of the tendinous arch of pelvic fascia
Uterine tubes are also called what?
what are the parts?
Fallopian tubes
Infundibulum (means funnel)
it’s associated with the fringe called “fimbriae”
one specific fimbrion contacts the ovary and that’s called the ovarian fimbrion
then you go into the ampulla of the uterine tube.
just before you get in the uterus you end up with another isthmus (of the uterine tube)
lastly the uterine part of the uterine tube. (WE CANNOT SEE THIS!!)
whats the opening on the end of the infundibulum of the uterine tube?
abdominal osteum
What’s the opening that goes from the uterine part of the uterine tube?
Uterine Osteum
what is the course of the oocyte
it goes from ovary to abdominal osteum to get to the infundibulum of the uterine tube, course into the ampulla of the uterine tube, keep going through the ampulla till you get to the isthmus of the uterine tube, then to the uterine part, through the uterine Osteum, into the uterine cavity, through the internal uterine Os, into the cervical canal, through the external uterine os, and on into the vagina.
