Examples of ilium in the following topics:

  • Ilium

    • The ilium is the uppermost and largest bone of the pelvis.
    • The ilium is the uppermost and largest bone of the pelvis.
    • The human ilium is divisible into the body and the ala, or wing.
    • The ilium is the uppermost bone of the pelvis and extends laterally.

  • Ischium

    • Situated below the ilium and behind the pubis, the superior portion of this bone forms approximately one third of the acetabulum, which articulates with the femoral head to form the hip joint.
    • The ischium is located below the ilium and behind the pubis.
    • The ischium is labeled at the bottom left of the ilium.

  • False and True Pelves

    • The true (or lesser) pelvis is bounded in front and below by the pubic symphysis and the superior rami of the pubis; above and behind, by the sacrum and coccyx; and laterally, by a broad, smooth, quadrangular area of bone, corresponding to the inner surfaces of the body and superior ramus of the ischium, and the part of the ilium below the arcuate line.
    • The false (or greater) pelvis is bounded on either side by the ilium.
    • In front it is incomplete, presenting a wide interval between the anterior borders of the ilia; behind is a deep notch on either side between the ilium and the base of the sacrum.

  • Pubis

    • The pubic bone articulates with the ilium and the ischium on each hip.
    • (1) sacrum, (2) ilium, (3) ischium, (4) pubis: 4a-body; 4b-superior ramus; 4c-inferior ramus, (5) pubic symphisis, (6) acetabulum, (7) obturator foramen, (8) coccyx, (red dotted line) linea terminalis.

  • Overview of the Appendicular Skeleton

    • In some vertebrates, including humans, the ox coxa is comprised of three bones: the ilium, ischium, and pubis.

  • Absorption of Monosaccharides, Amino Acids, Dipeptides, Tripeptides, Lipids, Electrolytes, Vitamins, and Water

    • Vitamin B12 is absorbed in the ilium and must be bound to intrinsic factor, a protein secreted in the stomach, in order to be absorbed.

  • Gross Anatomy

    • These bones are expanded into broad, flat plates, as in the cranium (skull), ilium (pelvis), sternum, rib cage, sacrum, and scapula.
