Which cavity houses the brain?

Which cavity houses the brain?

• A. Thoracic cavity
• B. Abdominal cavity
• C. Pelvic cavity
• D. Cranial cavity

Answer: (D)

The brain is housed in the cranial cavity, the space inside the skull. This protective cavity, bounded by skull bones, keeps the brain safe and is continuous with the spinal canal, with cerebrospinal fluid providing cushioning and nourishment. In contrast, the thoracic cavity contains the heart and lungs, the abdominal cavity holds digestive organs like the stomach and liver, and the pelvic cavity contains reproductive and some urinary organs. So the brain’s home is the cranial cavity.
