Flashcards in Pelvic Anatomy Deck (100)
Name the four bones that comprise the bony pelvis.
sacrum, coccyx, left and right innominate bones (ilium, ischium, and pubis)
T/F? The true pelvis is larger and completely enclosed.
FALSE: It's *smaller* and completely enclosed.
T/F? The false pelvis is larger and incompletely enclosed.
What organs are in the true pelvis?
bladder, uterus, ovaries, fallopian tubes, and adnexa
These pelvic ligaments can be classified as those which 'bind the pelvic bones together'.
These pelvic ligaments can be classified as those which 'support the uterus and ovaries'.
Name two kinds of suspensory ligaments.
uterine and ovarian
This uterine ligament arises superiorly and laterally from the uterus and inferiorly from the vagina to provide primary support for the uterus.
This uterine ligament extends posterolaterally from the cervix, encircles the rectrum, and inserts onto the fascia over the sacrum.
This uterine ligament is situated anterior and inferior to the broad ligaments and fallopian tubes & attaches the cornu to the anterior pelvic wall.
This uterine ligament extends from the lateral aspects of the uterus and attaches to the lateral pelvic side walls.
Name the four uterine suspensory ligaments.
This ligament divides the true pelvis into anterior and posterior compartments. Ovaries are attached to the posterior side.
This is the space within the peritoneal cavity located posterior to the broad ligaments.
This ovarian ligament attaches the inferior ovary to the uterine cornu posterior to the fallopian tube on each side.
This ovarian ligament is one continuous tissue that connects the ovary to the pelvic wall.
This ovarian ligament is a short peritoneal fold connecting the anterior border of the ovary with the posterior layer of the broad ligament.
T/F? Most pelvic muscles are paired structures that form the limits of the pelvic space.
What are the two groups of pelvic muscles?
true and false (abdomino-pelvic)
This pelvic muscle forms the anterior margin of the abdominal and pelvic spaces, extending from the xiphoid process to the symphysis pubis.
This pelvic muscle resembles a corset, wrapping around the trunk from back to front, and intersects the rectus abdominis.
This pelvic muscle originates at the lower thoracic vertebrae and extends laternal and anterior as it courses throuth the lower abdomen, along the pelvic side wall to eventually insert on the lesser trochanter.
Name the three false pelvic muscles.
rectus, transversus, iliopsoas
This muscle connects the lumbar spine to the femur.
The muscle connects the iliac crest to the femur.
The primary purpose of these muscles is to hold the pelvic organs in place.
'true' pelvic muscles
This triangular muscle arises from the antero-lateral wall of the pelvis, extending from the brim of the true pelvis and exiting through the lesser sciatic foarmen to insert on the greater trochanter of the femur.
This muscle group lines the lateral walls of the true pelvis.
This pelvic muscle arises from the sacrum, passes laterally through the greater sciatic notch, and inserts on the greater trochanter of the femur.
