  25. 25Posterior intercostal arteries of the first two spaces are branches from ________Superior intercostal artery

  33. 33____ to ____ nerves are have corresponding ribs that are floating, so it pass directly into the abdominal wall10th to 11th
  34. 34_________ a thin muscular and tendinous septum that separates the chest cavity above from the abdominal cavity belowDiaphragm
    (most important muscle of respiration)
  35. 35What are the origin of the diaphragm?Sternal Part, Costal Part and Vertebral Part
  36. 36Openings of diaphragmInferior Vena Cava(T8), Esophagus (T10), vagus nerve(with esophagus), aorta(T12)
  37. 37Blood Supply of diaphragm in costal margin or lower 5Intercostal and subcostal arteries
  38. 38Blood supply of Diaphragm in main mass of fibersRight and Left Inferior Phrenic Arteries from Abdominal Aorta
  39. 39Nerve Supply of Diaphragm (Motor and Sensory)Motor-right and left phrenic (CN 3, 4 and 5)
    Sensory - Parietal Pleural and Peritoneum Covering ( Phrenic Nerve CN 3, 4 and 5) and Peripheral Part (Lower 6 Intercostal Nerve)
  40. 40What are Lumbosacral Arches (Arcuate Ligaments)?Ligaments that connects the diaphragm with the posterior wall
  41. 41What is this ligament that creates aortic hiatus and passes anteriorly to the aorta then goes to the diaphragm?Median Arcuate Ligament
    (Blood can circulate via the pancreaticoduodenal arcade and also known as Psoas Fascia)
  42. 42What is the ligament around the Quadratus Luborum Muscle?Lateral Arcuate Ligament
    (extends from L1 to 12th rib)
  43. 43What vertebral level is Suprasternal Notch?T2/T3
  44. 44What vertebral level is the end of arch of aorta and the location where azygos vein enters superior vena cava?T4
  45. 45What vertebral level is the Angle of Louis and Manubriosternal Junction?T4/T5
  46. 46What vertebral level does the thoracic duct crosses midline?T5
  47. 47What vertebral Level is the Superior Border of Scapula?T2
  48. 48What vertebral level is the inferior angle of scapula?T7
  49. 49What vertebral level is the caval opening in diaphragm, hemi-azygos veins crosses to the left and left phrenic pierces diaphragm?T8
  50. 50What vertebral level is the aortic opening in diaphragm?T12
  51. 51What vertebral level is the Esophageal Opening in diaphragm?T10
  52. 52What is thoracic outlet?Superior Opening of the thoracic cavity
  53. 53True or False When Exhaling air out the diaphragm is contracted.False
    Diaphragm relaxes when breathing out, lowering thoracic volume and increasing intra-thoracic pressure

  59. 59A congenital condition where the heart is located on the right side of the thorax instead of leftDextrocardia
  60. 60Anatomical Deformity where the ribs and sternum protrudes anteriorlyPectus Carinatum
  61. 61Anatomical Deformity where ribs and sternum creates a depression in the center of the chestPectus Excavatum

  63. 63A condition where fluid gathers within the pericardial cavity which leads to restricting hearts ability to function normally.Pericardial Effusion or Cardiac Tamponade
  64. 64Explain Superior Vena Cava SyndromeObstruction of the SVC with the most common cause is a cancerous tumor which may lead to dyspnea, facial swelling, neck distension and cough
