Which cavity is formed by the cranial bones and contains the brain?

• A. Cranial cavity
• B. Spinal cavity
• C. Mediastinum
• D. Pleural

Answer: (A)

Understanding body cavities: the brain sits in a protected space formed by the skull bones. This space is the cranial cavity, located at the top of the dorsal body cavity and bounded by the cranial bones. The spinal cavity runs inside the vertebral column and contains the spinal cord. The mediastinum is the central part of the thoracic cavity housing the heart and major vessels, while the pleural cavities surround the lungs within the thorax. So the cavity formed by the cranial bones that contains the brain is the cranial cavity.
