Parietal pleura
The parietal pleura (from Latin: paries, lit. 'wall') lines the inside of the thoracic cavity. This includes the inner surface of the rib cage and the upper surface of the diaphragm, as well as the side surfaces of the mediastinum. It joins the visceral pleura at the pericardial base of the pulmonary hilum and pulmonary ligament as a smooth but acutely angled circumferential junction known as the hilar reflection. The thoracic cavity is set apart from the thoracic wall by the endothoracic fascia.
