Human skeleton system overview (Senior)– 3D model and animation – in English

Summary

The human skeleton system is made up of 206 bones that give our body shape, provide structure, and protect vital organs. Bones come in different types, such as long bones in the forearms and thighs, and short bones in the wrists, feet, and ears. The ribcage shields the heart and lungs, the skull encases the brain, and the spine safeguards the delicate spinal cord. Beyond protection, the skeleton allows us to stand, sit, and maintain posture while keeping all organs in place, highlighting its crucial role in both support and defense within the human body.
