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

The Diaphragm:1

derives its motor innervation from the lower six intercostal

nerves

2

derives its sensory nerve supply from the phrenic nerve

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

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

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
