What is the auricular surface of ilium?

Behind the iliac fossa is a rough surface, divided into two portions, an anterior and a posterior. The anterior surface (auricular surface), so called from its resemblance in shape to the ear, is coated with cartilage in the fresh state, and articulates with a similar surface on the side of the sacrum.

Where is the auricular surface of ilium?

More inferiorly is the posterior inferior iliac spine. This is located at the inferior end of a large, roughened area called the auricular surface of the ilium. The auricular surface articulates with the auricular surface of the sacrum to form the sacroiliac joint.

Which bones contain an auricular surface?

The lateral surfaces of the upper two or three sacral vertebrae form an ear-shaped “auricular” surface, which articulates with the ilium on each side.

What is the function of the auricular surface?

Each wing carries on his dorsal part an oval articular surface covered with cartilage, termed auricular surface, for articulation with the ilium. The sacral tuberosity is the roughed surface, dorsal to the auricular surface, for attachment of ligaments.

What is the external surface of the ilium?

The external surface, known as the dorsum ossis ilium, is directed backward and lateralward behind, and downward and lateralward in front. It is smooth, convex in front, deeply concave behind; bounded above by the crest, below by the upper border of the acetabulum, in front and behind by the anterior and posterior borders.

What kind of shape is the wing of Ilium?

What kind of surface is behind the iliac fossa?
