  1. Slacker’s Guide to Thoracic Gross Anatomy Prepared by Mike Ori

  2. Caveat Emptor • As with all slackers guides, I have omitted, condensed, and misunderstood information so don’t complain if I got something wrong, after all, you’re a slacker. • Also, it goes without saying that the faculty has not vetted the information in any way. Always refer to their notes and lectures for the last word.

  3. CT and Such • You’re probably best off working on an interactive system try • http://www.imaios.com/en/e-Anatomy • CPR Radiograph key from Slice-o lecture is important

  4. Structures from labs • Veins • Azygous vein (c) • Hemiazygous vein (c) • Posterior intercostal veins (c) • Pulmonary vein (c) • Nerves • Intercostal nerves (c) • Phrenic nerve (c) • Viscera • Lungs • Horizontal fissure (right only) (c) • Inferior lobe (left and right) (c) • Middle lobe (right only) (c) • Oblique fissure (left and right) (c) • Superior lobe (left and right) (c) • Pleura • Parietal pleura (c) • Visceral pleura (c) • Primary (main) bronchi (c,r) • Secondary (lobar) bronchi (c) • Superior lobar bronchi (left and right) (c) • Middle lobar bronchus (right only) (c) • Inferior lobar bronchi (left and right) (c) • Trachea (c,r) • Viscera • Esophagus (c, r) • Thoracic duct (c) • Trachea (c,r) • Bones • Ribs (b, r) • Sternal Body (b,r) • Manubrium (b) • Sternal angle (b) • Xiphisternum (xiphoid process) (b) • Muscles • External intercostal (c) • Internal intercostal (c) • Diaphragm (c) • Arteries • Pulmonary artery (c) • Subclavian artery (c,r) • Internal thoracic artery (c) • Anterior intercostals arteries (c) • Thoracic (descending) aorta (c,r) • Posterior intercostal arteries (c) Arteries and Veins Ascending aorta (c,r) Aortic Arch (c,r) Brachiocephalic artery (c,r) Right subclavian artery (c) Right common carotid artery (c) Left common carotid artery (c,r) Left subclavian artery (c,r) Descending aorta (c,r) Posterior intercostal arteries (c) Inferior vena cava (c,r) Pulmonary trunk (c,r) Left pulmonary artery (c) Right pulmonary artery (c) Superior vena cava (c,r) Azygous vein (c) Hemiazygous vein (c) Posterior intercostal veins (c) Brachiocephalic veins (c) Nerves Phrenic nerve (c) Thoracic sympathetic chain (c) Greater splanchnic nerve (c) Vagus nerve (c) Anterior vagal trunk (c) Posterior vagal trunk (c) Esophageal plexus (c) Left recurrent laryngeal nerve (c) These are set out exactly as found in the labs so there are duplicates

  5. Structures from Labs •  Viscera • Anterior interventricular sulcus • Chordaetendineae • Coronary sulcus • Fossaovalis • Interventricular septum • Left atrium • Openings of pulmonary veins • Left auricle • Left ventricle • Aortic valve • Mitral (bicuspid) valve • Pericardial sac • Fibrous pericardium • Parietal (serous) pericardium • Visceral (serous) pericardium = epicardium • Posterior interventricular sulcus • Right atrium • Cristaterminalis • Opening of coronary sinus • Opening of inferior vena cava • Opening of superior vena cava • Right auricle • Right ventricle • Moderator band • Pulmonary valve • Tricuspid valve • Muscles • Papillary muscles • Anterior papillary muscle – both right and left ventricles • Posterior papillary muscle – both right and left ventricles • Septal papillary muscle – right ventricle only • Pectinate muscle (right atrium) • Trabeculaecarnae (ventricles) • Vessels • Aorta • Left coronary artery • Anterior interventricular artery • Circumflex artery • Right coronary artery • Marginal artery • Posterior interventricular artery • Coronary sinus • Great cardiac vein • Middle cardiac vein • Small cardiac vein • Ligamentumarteriosum • Pulmonary trunk • Pulmonary arteries • Pumlonary veins
