Solution

The correct option is A Atlas

The atlas is one of the two upper cervical vertebrae, also known as C1, which is the topmost vertebra of the spinal column. It is the vertebra that is in contact with the occipital bone, a flat bone located at the back portion of the head. This first cervical bone is named after the mythical Greek god who carried the world on his shoulders, as its function is to support the globe of the head. Together with the second vertebra, the axis, it is responsible for the wide range of motion of the head.
