Male and Female Pelvis Flashcards
Osteology of pelvis (5)
Ischium Pubis Ileum Sacrum Pubic symphysis
the socket of the ball-and-socket joint of the hip
acetabulum
landmarks above and below ischial spine
Greater (above) and lesser (below) sciatic notch
houses pelvic cavity and support for perineum
lesser, true pelvis
protection for inferior abdominal viscera
greater, false pelvis
greater and lesser pelvis are divided by
the oblique plane of the pelvic inlet
Borders of pelvic inlet (aka superior pelvic aperture)
Superior pubic ramus
arcuate line (ilium)
sacral promontory
pubic crest
borders of pelvic outlet (inferior pelvic aperture)
pubic symphysis inferior pubic ramus, ischial ramus ischial tuberosities sacrotuberous ligamet tip of coccyx
joints of pelvis
sacroiliac
pubic symphysis
lumbosacral
strong weight bearing joint of pelvis
sacroiliac
fibrocartilaginous interpubic disc
pubic symphysis
facets of the S1 vertebrae interlock with facets of the L5 vertebrae to make a zygopophyseal joint called the
lumbosacral joint
ligaments of pelvis
iliolumbar
sacroiliac
sacrotuberous
sacrospinous
ligaments radiating from L5 vertebra to ilium
iliolumbar ligament
assist in suspending the sacrum between the iliac bones
posterior and anterior sacroiliac ligaments
massive ligament that passes from posterior ilium and lateral sacrum and coccyx to ischial tuberosity making a large sciatic foramen
sacrotuberous ligament
runs from lateral sacrum and coccyx to ischial spine
divides it into the greater sciatic foramen and lesser sciatic foramen
sacrospinous ligament
anterior pelvic wall
pubis bone
pubic symphysis
lateral pelvic wall
obturator internus muscle
obturator fascia
- tendinous arch
posterior pelvic wall
sacrum
sacroiliac joints
piriformis
pelvic floor is formed by
pelvic diaphragm muscle
