Paired triangular flat muscles that cover the inner curved surface of the ioliac fossae
Arise from the iliac fossae and join the psoas major muscles to form the lateral walls of the pelvis
iliacus muscle
pelvic cavity found below the brim of the pelvis
true pelvis
one of two muscles of the pel;vic cavity diaphragm that stretch across the floor of the pelvic caivty like a hammock
Supporting the pelvic organs and surrounding the urethra, vagina and rectum
broad thin muscle that consists of the pubococcygeus, iliococcygeus and puborectalis muscles
levitor ani
one of the two muscles in the pelvic diaphragm located on the posterior pelvic floor where is supports the coccyx
coccygeus muscle
flat pyramid muscle arising from the anterior sacrum, passing through the greater sciatic notch to insert into the superior aspect of the greater trochanter of the femur
serves to rotate and abduct the thigh
piriformis muscle
parallel longitudinal lines commonly seen in the muscle tissue when imaged sonographically
appear as hyperochoic parallel lines runnin in long axis of the hyperechoic muscle tissue
striations
bony ridge on the inner surface of the ilium and pubi cones that divides the true and false pelves
iliopectineal line
paired muscle that originates at the transverse process of the lumbar vertebrae and extends inferiorly through the false pelvis on the pelvic sidewall where it unites with the iliacus muscle to form the iliopsoas muscle before inserting into the lesser trochanter of the femur
servise to flex the thigh toward the pelvis
psoas muscle
portion of the pelvis found above the brim
that portion of the abdominal cavity cradled by the iliac fossae
false pelvis
triangular sheet of muscle that arises from the anterolateral pelvic wall and surrounds the obturator foramen
passes through the lesser sciatic foramen and inserts into the medial aspect of the greater trochanter of the femur
serves to rotate and abduct the thigh
obturator internus muscle
