How does the chapter define the difference between the dorsal and ventral cavities?
The dorsal cavity is located at the back of the body and contains the brain and spinal cord, while the ventral cavity is situated at the front and includes the thoracic cavity and the abdominopelvic cavity, separated by the diaphragm.
The dorsal cavity is defined as the space that houses the brain in the cranial cavity and the spinal cord in the spinal cavity. In contrast, the ventral cavity is located at the front of the body, encompassing the thoracic cavity above the diaphragm and the abdominopelvic cavity below it. The diaphragm serves as the dividing structure between the thoracic and abdominal cavities.

- Dorsal cavity contains the brain and spinal cord.
