uterine tube means what
Fallopian tube
2 hiatuses formed by levator ani
urogenital and anal hiatus
urogenital hiatus contains what
vagina and urethra
vestibule def
vaginal opening (space)
uterus shape
vagina to the back and then bending and uterus goes forward
fornices of the cervix
holes on top of vagina made from cervix pushing in it
- anterior fornix
- posterior fornix
- lateral fornix
parous vs nulliparous cervix
nulliparous = external os is a small circle parous = external os is a retracted enlarged hole
position of uterus: flexion angle def
angle between uterus and cervix (between longitudinal uterine axis and longitudinal cervical axis)
normal flexion angle of uterus
anteflexed (uterus bent forward compared to cervix)
position of uterus: version angle def
angle between the cervical canal and the vagina (longit cervical axis and longit vaginal axis)
normal version angle of the uterus
anteverted (vagina bent forward compared to cervix)
uterus parts
- fundus (top), related to abdomen
- body of uterus (endo, myo and perimetrium)
- isthmus (narrowing in bottom)
- internal os of cervix
- cervical canal
- external os of cervix
most common tumor of the genital tract
fibroids (benign, CT and collagen. non cancerous)
diff types of fibroids (locations)
- closing fallopian tube
- in vagina
- hanging off top of uterus
- etc
3 supports of the uterus
- muscular
- endopelvis fascia
- broad ligament and assoc structures
- other ligaments
muscular support of uterus (2)
- levator ani and its fascia
- perineal body (in the perineum)
endopelvis fascia (bands of CT) support of the uterus
- transverse cervical (cardinal) lig (upper vagina + cervix to lateral pelvic wall. contains uterine and vaginal vessels
- pubocervical ligs (cervix to pubic bones. 2 bands)
- sacrocervical ligaments (cervix + upper vagina to lower sacrum). travels in the uterosacral fold
broad lig + assoc structure supporting uterus
- broad ligament (like a curtain covering the fallopian tubes)
- round ligament of the uterus
- ovarian ligament (ligament of the ovary)
- suspensory ligament of the ovary
what is the uterosacral fold
fold in back wall of cervix made by rectum being there and pushing the sacrocervical lig around (sacrocervical ligs surround the rectum)
clinical significance of uterosacral fold
if any support of uterus (like this one) becomes lax, cervix can descend in the vagina or vestibule
parts of the Fallopian tube (uterine tube)
- fimbriae
- infundibulum
- ampulla (wide, site of fertilization)
- isthmus (narrow near uterus)
- intramural (part of uterine wall)
Fallopian tube relates to what ligament
lies in the upper boarder of the broad ligament
some sites of ectopic pregnancies
- abdomen (fimbriae didn’t catch the egg)
- fallopian tube
- cervix
most common site of ectopic pregnancies
Fallopian tube
