Which term refers to a part of the hip bone?

The term that refers to a part of the hip bone is "Ilium." The ilium is the largest of the three bones that make up the hip bone, also known as the pelvic bone. It is located at the top of the pelvic structure and contributes to the formation of the iliac crest, which can be felt on the sides of the hips. The ilium plays an essential role in supporting the weight of the body when sitting and standing and is also involved in locomotion.

In contrast, the ischium and pubis are the other two bones that comprise the hip bone. The ischium forms the lower and back part of the hip bone, contributing to the sit bones, while the pubis constitutes the front portion of the bone. The acetabulum, on the other hand, refers to the cup-shaped socket that holds the head of the femur, forming the hip joint, rather than being a distinct part of the bones of the hip itself.
