Which is the most protective cavity in the body?
The cranial cavity is the most protective body cavity. It surrounds the brain in bone, soft tissue, and a protective layer of liquid which reduces the strain and damage from impacts. The vertebral cavity is similar, but has gaps were the nerves must enter or exit. Like the other body cavities, the dorsal cavity is surrounded in a thin layer
