Body Cavities and Membranes: Anatomy of Protection and Organization

This video lecture covers the major body cavities and membranes, explaining their roles in protecting and organizing organs. It details the dorsal and ventral cavities, including their subdivisions like the cranial, vertebral, thoracic, and abdominopelvic cavities. The lecture also discusses minor cavities and the membranes lining these cavities, such as the meninges and serous membranes. Key directional terms related to these membranes are explained, and the video concludes with a recap of the main points.
