Which part of the body does the pubis belong to?

The pubis is a crucial part of the pelvic girdle, which is located in the lower part of the torso. The pelvic girdle is formed by the fusion of three bones: the ilium, ischium, and the pubis. This structure supports the weight of the upper body when sitting and standing and provides attachment points for various muscles. Additionally, it protects vital organs in the lower abdomen and houses components of the reproductive system.

In contrast to the other options, the shoulder girdle is primarily involved in connecting the arm to the trunk, while the axial skeleton refers to the central core of the body, including the skull, vertebral column, and rib cage. The spinal column is specifically part of the axial skeleton, focusing on the vertebrae that protect the spinal cord. Thus, the pubis's location and function distinctly categorize it within the pelvic girdle.
