What is protected in the cranial cavity?

The cranial cavity is a vital anatomical structure that houses and protects the brain, which is the central organ of the nervous system. This area is encased by the skull, providing a hard protective barrier against external injuries and environmental threats. The brain is critical for controlling various bodily functions, processing sensory information, and coordinating actions.

While the heart, liver, and kidneys are essential organs, they are located in other parts of the body: the heart is situated in the thoracic cavity, the liver is in the abdominal cavity, and the kidneys are also located in the posterior abdominal cavity. Thus, within the context of the cranial cavity specifically, the brain is the organ that is safely contained and protected.
