Slideshow: Hip Bone
The hip bone (os coxae) is made up of three components: the pubis, ischium, and ilium, which converge at the acetabulum. Various features and muscles attached to the hip bone are discussed, including muscle origins, insertions, and actions, emphasizing their anatomical significance and role in hip movement. This document serves as an anatomical guide to the hip bone, detailing the structure and associated musculature essential for understanding movement and support.
