Human skeleton, computer artwork. The human skeleton has 206 bones. The skull (at top) protects the brain. The ribs of the chest (at upper centre) enclose the heart and lungs. The pelvis (at centre) protects the lower abdominal organs. The flexible backbone runs from the skull to the pelvis and protects the spinal cord. The long leg and arm bones provide support and, in combination with the arm and leg muscles, allow dexterity and locomotion.
