The ilium of the pelvis is divisible into two parts, the body and the ala; the separation is indicated on the internal surface by a curved line, the arcuate line, and on the external surface by the margin of the acetabulum. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Introduction ( classes Long bones body or Diaphysis Medullary canal Medical Subject Headings ( MeSH) is a huge Controlled vocabulary (or metadata system for the purpose of indexing journal articles and books Elsevier, the world's largest Publisher of Medical and Scientific literature, forms part of the Reed Elsevier group The pelvis (pl pelvises or pelves) or pelvic girdle is the irregular bony structure located at the base of the spine (properly known The acetabulum is a concave surface of the Pelvis. The head of the femur meets with the pelvis at the acetabulum forming the hip Joint The name comes from the Latin, meaning "groin" or "flank. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. " 
The body enters into the formation of the acetabulum, of which it forms rather less than two-fifths. The acetabulum is a concave surface of the Pelvis. The head of the femur meets with the pelvis at the acetabulum forming the hip Joint
Its external surface is partly articular, partly non-articular; the articular segment forms part of the lunate surface of the acetabulum, the non-articular portion contributes to the acetabular fossa.
The internal surface of the body is part of the wall of the lesser pelvis and gives origin to some fibers of the Obturator internus. The obturator internus muscle originates on the medial surface of the Obturator membrane, the Ischium near the membrane and the rim of the pubis.
Below, it is continuous with the pelvic surfaces of the ischium and pubis, only a faint line indicating the place of union. The ischium forms the lower and back part of the Hip bone ( os coxae) For the bone in many mammals often called the penis bone see Baculum The android pubic bone is the Ventral and Anterior
Male pelvis. The wing of ilium (or ala) is the large expanded portion which bounds the Greater pelvis laterally The crest of the ilium (or iliac crest) is the superior border of the Wing of ilium and the superolateral margin of the Greater pelvis.
