 Although no membrane physically divides the abdominopelvic cavity, it can be useful to distinguish between the abdominal cavity, the division that houses the digestive organs, and the pelvic cavity, the division that houses the organs of reproduction.Together the cranial cavity and spinal (or vertebral) cavity can be referred to as the dorsal body cavity.In the posterior (dorsal) cavity, the cranial cavity houses the brain, and the spinal cavity encloses the spinal cord.
