Describe the boundaries of the thorax and its subdivisions, including pleural a
cavities and their linings
• The boundaries of the thoracic cavity are the ribs (T1-T12), the diaphrag
column
• 2 subdivisions of the thoracic cavity → Pleural and mediastinal
○ Pleural cavity
§ Filled with 2 pleural sacs containing left and right lung, having
membranes that cover the cavity in its entirety.
§ Visceral pleura: Cover the lungs
§ Parietal pleura: Cover internal surfaces of the thoracic cavity
§ Lungs stick to the pleura, parietal pleura lining the mediastinu
visceral pleura lining surface of the lung, when diaphragm co
expand, lungs follow
○ Mediastinal cavity
§ Space between the 2 pleural cavities
§ Contains, heart, thymus gland, portions of the oesophagus a
well as other important vasculature
Identify the bones that constitute the thoracic cage and their surface markings
• Thoracic cage bones → sternum, thoracic spine, clavicle and ribs
• Ribs are held to the sternum by costal cartilage - Intercostal cartilage is
○ 12 ribs in total: 1-7 attached directly to the sternum, 8-10 attached
and 11-12 do not have anterior attachment → floating ribs
• Sternum is used to protect the internal thoracic viscera (heart, lungs and
• Superior → inferior portions of the sternum:
○ Jugular notch, Manubrium, Sternal angle, Body, Xiphoid process
