Questions Diaphragm

  1. 1. Questions Diaphragm
  2. 2. The right crus of the diaphragm: 1 arises from the upper three lumbar vertebral bodies 2 is larger than the left crus 3 is composed mainly of smooth muscle 4 surrounds the oesophagus 5 is overlapped by the inferior vena cava

  4. 4. The Diaphragm: 1 derives its motor innervation from the lower six intercostal nerves 2 derives its sensory nerve supply from the phrenic nerve 3 derives its blood supply, in part, from a terminal branch of the internal mammary artery 4 has a left dome whose summit is at a higher level than that of the right dome 5 has muscle fibres which arise from the xiphisternum
  5. 5. The Diaphragm: 1 derives its motor innervation from the lower six intercostal nerves F 2 derives its sensory nerve supply from the phrenic nerve T 3 derives its blood supply, in part, from a terminal branch of the internal mammary artery T 4 has a left dome whose summit is at a higher level than that of the right dome F 5 has muscle fibres which arise from the xiphisternum T
  6. 6. Concerning the phrenic nerve 1 it innervates the diaphragmatic pleura 2 it is normally derived from the 1st, 2nd and 3rd cervical spinal cord segments 3 it traverses the aortic hiatus in the diaphragm 4 it innervates the diaphragmatic peritoneum 5 transection of the phrenic nerve will manifest itself as a fixed depression of the ipsilateral
