The base of the skull, extends a flexible column called _________.
Vertebral Column
From the base of the skull, a flexible chain of 33 small bones called vertebrae runs down the back – this is the vertebral column (backbone or spine).
It encloses and protects the spinal cord and supports the body while allowing bending.
Atlas is only the first vertebra, which supports the skull; it is not a column.
Axis is the second vertebra, which lets the head turn; it is also a single bone.
Sternum is the breastbone in the front of the chest, not attached to the base of the skull.
Hence, the answer is Vertebral Column.
