The scull is defined as which of the following?

The scull is defined as which of the following?

• A. Encloses and protects the brain and primary sensory organs
• B. Encloses the heart and lungs
• C. Supports the spinal cord
• D. Attaches to the jaw

Answer: (A)

The skull’s main role is to enclose and protect the brain and the primary sense organs. It forms a protective case around the brain and houses the eye sockets, ear cavities, and nasal/oral structures that are essential for sensing the world. The heart and lungs sit in the thoracic cavity protected by the rib cage, not the skull. The spinal cord is sheltered by the vertebral column, while the jaw (mandible) attaches to the skull at joints but its primary function isn’t defining what the skull does. So, enclosing and safeguarding the brain and primary sensory organs best captures what the skull does.
