The crest of the ilium (or iliac crest) is convex in its general outline but is sinuously curved, being concave inward in front, concave outward behind. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Introduction ( classes Long bones body or Diaphysis Medullary canal Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group The ilium of the Pelvis is divisible into two parts the body and the ala the separation is indicated on the top surface by a curved line the arcuate line and on the

Anatomy
It is thinner at the center than at the extremities, and ends in the anterior and posterior superior iliac spines. The posterior border of the ala, shorter than the anterior also presents two projections separated by a notch the posterior superior iliac spine and the Posterior inferior iliac
The surface of the crest is broad, and divided into external and internal lips, and an intermediate line.
About 5 cm behind the anterior superior iliac spine there is a prominent tubercle on the outer lip. The anterior superior iliac spine (ASIS is an important landmark of surface anatomy
To the external lip are attached the Tensor fasciæ latæ, Obliquus externus abdominis, and Latissimus dorsi, and along its whole length the fascia lata; to the intermediate line the Obliquus internus abdominis. The tensor fasciae latae or tensor fasciæ latæ is a Muscle of the Thigh. The external oblique muscle (of the abdomen (also external abdominal oblique muscle) is the largest and the most superficial (outermost of the three flat muscles of the lateral The latissimus dorsi (plural latissimi dorsi is the large flat dorso-lateral muscle on the trunk posterior to the arm and partly covered by the Trapezius on its median The fascia lata is the Deep fascia of the Thigh. Thickness It is an investment for the whole of the thigh but varies in thickness in different parts The internal oblique muscle (of the abdomen is the intermediate muscle of the abdomen lying just underneath the External oblique and just above (superficial to the Transverse
To the internal lip, the fascia iliaca, the Transversus abdominis, Quadratus lumborum, Sacrospinalis, and Iliacus. The iliac fascia is a Fascia in the pelvic area of the Human body. The transversus abdominis muscle, also known as the transversalis muscle and transverse abdominal muscle, is a muscle layer of the anterior and lateral Abdominal The Quadratus lumborum is irregular and quadrilateral in shape and broader below than above The Erector spinæ (or Sacrospinalis in older texts a bundle of Muscles and Tendons and its prolongations in the thoracic and cervical regions lie in The Iliacus is a flat triangular muscle which fills the Iliac fossa.
Clinical significance
The iliac crest has a large amount of red bone marrow, and thus it is the site of bone marrow harvests (from both sides) to collect the stem cells used in bone marrow transplantation. Bone marrow is the flexible tissue found in the hollow interior of Bones In adults marrow in large bones produces new Blood cells It constitutes 4% of Stem cells are cells found in most if not all multi-cellular Organisms.
