Cranium
Tendron
Diaphragm
Rib cage E. Pericardium
Answer is Right!
Answer is Wrong!
The answer is B. Tendron.
A cranium is the bony structure that encloses the brain. A rib cage is a bony structure that protects the lungs and heart. A diaphragm is a muscular structure that separates the chest cavity from the abdominal cavity. A pericardium is a sac that surrounds the heart.
A tendon is a tough, fibrous cord that attaches muscle to bone. Tendons are not bones, and they do not enclose any organs. Therefore, they are the odd one out in the list.
