What is dorsal cavity?
The dorsal cavity lies close to the spine in the posterior portion of the body. The dorsal cavity contains the spinal column, central nervous system (i.e., brain and spinal cord), and meninges (i.e., tissue that surrounds the brain and spinal cord).
Which body cavities are anterior or ventral?
The ventral body cavity is a human body cavity that is in the anterior (front) aspect of the human body. It is made up of the thoracic cavity, and the abdominopelvic cavity. The abdominopelvic cavity is further divided into the abdominal cavity and pelvic cavity, but there is no physical barrier between the two.
