-
The largest of the three bones which constitute the os innominatum in the foetus and child. It was probably so called from its seeming to support the intestine ilion; or, perhaps, because its crest is curved upon itself. This portion of the os innominatum is usually so called in the adult. The posterior surface is called Dorsum, the internal Venter. The upper semicircular edge is the Crista or Spine, at the anterior part of which is the anterior and superior spinous process; and, below, the anterior and inferior spinous process. At the back part of the spine are two spinous processes, the posterior and superior, and posterior and inferior. See Iliac.
