The body cavity bounded by the ribs is the thoracic cavity. It contains the heart, lungs, and other structures involved in breathing and circulation.
Ribs?
The part of the body enclosed by the ribs and sternum is the thorax or chest cavity. This cavity contains the heart, lungs, and other vital organs that help with breathing and circulation. It plays a crucial role in protecting these organs and supporting proper respiratory function.

The thin tissue that holds the organs in place in the body cavity of frogs is called the mesentery. It attaches the internal organs to the body wall and provides support and stability for the organs within the abdominal cavity.

The muscles under the ribs in the human body help with breathing by expanding and contracting the chest cavity to allow air to enter and exit the lungs.
Usually the bones are the perimeter of the cavity like the skull is the perimeter of the cranial cavity or the ribs of the abdominal pelvic cavity. But the spine is in the spinal cavity, I'm not 100% sure if the pelvis is in the pelvic cavity off the top of my head, so in short yes there are bones in certain body cavities.
