- n. The region in mammals between the pleural sacs, containing the heart and all of the thoracic viscera except the lungs.
Century Dictionary and Cyclopedia
- n. In anatomy, a median septum or partition between two parts of an organ, or between two paired cavities of the body; especially, the membranous partition separating the right and left thoracic cavities, formed of the two inner pleural walls. Since in man these pleural folds do not meet, the term mediastinum is extended to the space between them.
