QuestionsDiaphragm
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
5is overlapped by the inferior vena cava

5is overlapped by the inferior vena cava T
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
5has muscle fibres which arise from the xiphisternum

Concerning the phrenic nerve1
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
5transection of the phrenic nerve will manifest itself as a fixed
depression of the ipsilateral

The Diaphragm
1
is innervated solely by the phrenic nerves
2
has a central tendinous portion which is circular in outline
3
forms the lower limit of the posterior mediastinum
4
forms the lower limit of the superior mediastinum
5
is traversed by the ganglionated sympathetic chain

Concerning the Diaphragm:
1 It is attached to the lower six costal cartilages
2 It gets its motor innervation from the 3rd, 4th and 5th cervical
segments of the spinal cord 3 It has the abdominal aorta going through the central tendinous
portion4 it is innervated peripherally by the intercostal nerves
5 it is normally fused with the inferior aspect of the fibrous
pericardium

Unilateral paralysis of the diaphragmatic
musculature 1 manifests itself on a plain AP chest radiograph as a depressed,
flattened hemidiaphragm2 manifests itself as a permanently elevated immobile
hemidiaphragm3 manifests itself as a depressed, immobile hemidiaphragm
4 causes the mediastinum to shift to the ipsilateral side
5 causes the diaphragm to move upwards on inspiration
