The human abdomen, or "tummy," does not contain any bones. However, it is surrounded by the ribcage, which consists of 24 ribs (12 pairs) that protect the organs in the abdominal cavity. The pelvis, composed of the hip bones, also supports the lower abdomen. The primary bones related to the abdominal area are the ribs and the pelvis.
The hip bones, sacrum, and coccyx form the framework that supports the lower abdomen. These bones provide stability and structure to the pelvic region, enabling it to bear weight and support the organs in the lower abdomen. Additionally, the pelvic bones serve as attachment points for muscles and ligaments that help with movement and support of the abdomen.
