coccyx
ischium
ilium

Explanation:

Identify the components of the coxal bone

Using the Skeletal Anatomy and Bone Identification knowledge points
The coxal bone (hip bone) is formed by three fused bones: the ilium, ischium, and pubis.

Determine the anatomical position of each component

Using the Skeletal Anatomy knowledge point

• The ilium forms the superior (upper) portion of the coxal bone.
• The pubis forms the anterior and inferior (front and lower) portion.
• The ischium forms the posterior and inferior (back and lower) portion, specifically the lowest part that you sit on.
• The coccyx is not part of the coxal bone; it is part of the vertebral column.
