True or False: The fossae is another name for the pleural cavities.

The statement is false because "fossae" refers to shallow depressions or cavities in a bone or organ, such as the fossae found in the skull or the human hand. In anatomical terms, the pleural cavities specifically refer to the two spaces in the thoracic cavity that house the lungs. These are the right and left pleural cavities, each separated by the mediastinum. The term "fossae" is not synonymous with pleural cavities, which have a more specific definition related to the respiratory system. Understanding these terms helps clarify the distinction between different anatomical structures and their proper nomenclature in relation to the body's cavities and spaces.
