The diagram provided shows a basic outline of the appendicular skeleton. Which number indicates the ilium?
The ilium is one of the fused bones that makes up the pelvis. In this diagram of the pelvis, we can see that the ilium is a large and broad bone
that creates the so-called wings of the structure.
In order to answer this question with confidence, let’s quickly identify all of the
bones indicated by numbers in this diagram.
One points to the finger bones, or phalanges. Two points to the radius, one of the two forearm bones. We can tell this one is the radius because it is broader at the wrist than the other
bone. Three points to the humerus. Four points to the scapula, commonly known as the shoulder blade. Five points to the ilium portion of the pelvis. Six points to the femur. Seven points to the tibia, and eight to the fibula.
This question asks us which number indicates the ilium. So the correct answer is five. In this diagram, the ilium is indicated by the number five.
