Which bone primarily supports the head and neck?

1. Vertebrae

2. Skull

3. Sternum

4. Clavicle

The correct answer is: Skull

The skull is the primary bone that supports the head and neck. It encases and protects the brain while providing structure for the face. The base of the skull connects with the vertebral column, allowing support and movement of the head. This anatomical connection enables the skull to maintain stability while allowing for essential functions such as vision and hearing. In contrast, while the vertebrae form the spinal column and provide support for the back and neck, they do not primarily support the head itself; that role is fulfilled by the skull. The sternum serves as a central point for rib attachment and does not play a role in supporting the head and neck. The clavicle, or collarbone, helps stabilize the shoulder but is not involved in directly supporting these parts of the body. Thus, the skull's unique structure and position make it the primary support for the head and neck.
