Pelvic Walls and Floor Flashcards
To learn the stuff you quite don't know yet
what is the function of the greater and lesser sciatic notch
allow passage of nerves , arteries and veins and muscles from the internal surface of the pelvis to the perineum and gluteal region
what is the ischial spine a good landmark for
pudendal nerve
how is the inguinal ligament formed
by the apopneruosis of the external oblique as it rolls over itself to create the anterior wall and floor of the inguinal canal
what do the sacrotuberous and the sacrospoinous ligaments support
posterior wall and floo roof the pelvic cavity
what is the combination of joints at the sacroiliac joints
plane synovial joint anteriorly
fibrous joint posteriorly
what is the plane syovial part of the sacroilaic joint supported by
anterior sacroiliac ligament
what is the fibrous joint of the sacroiliac joint supported by
posterior sacroiliac ligament
what is the insertion of the iliopoasos
lesser trochanter of the femur
what is the anterior rami infuriation of the psaos major from
lumbar plexus
what is the piriformis a good landmark for (pelvis)
the sciatic nerve and the pudenal nerve on its superior surface
what is the piriformis a good landmark for (gluteal region)
superior and inferior gluteal nerves and vessels lie on either side of the piriformis
sciatic nerve descendings from the greater sciatic notch beanth it
what is the function of the pubococcygeus
attach / support the vagina prostate gland and rectum
what is the relation of the iliocogeus of the leavtor ani
more lateral anterior to cocygeus
what does the leavtor ani do during forced expiration
contract
what happens to the leavtor ani to allow urination and defection
relaxation
what attaches to the perineal body
leavator prostate
pubovaginalis
external anal sphincter
perineal muscle
what fascia covers the internal walls
parietal pelvic fascia
what fascia overs the pelvic organs
visceral pelvic fascia
what is the function of the endopelvic fascia
acts as packing materially around the organs
what are the two types of the endopelvic fascia
loose and condensed
what is an example of endopelvic fascia loose
retropubic space
what is an example of the condensed endopelvic fascia
hypogastric sheath
what two things blend together as the organs perice the pelvic floor
parietal and visceral blend
what is the paracoplium
lateral extension fot he visceral fascia from the vagina to the tendinous arch
