Injury at this level of the spinal cord might injure the phrenic nerve. This nerve supplies the diaphragm, which permits inspiration and expiration. If this nerve is damaged, the impulses no longer reach the diaphragm and the diaphragm stops contracting.
1 The diaphragm is a musculotendinous, dome-shaped partition between the thoracic and abdominal cavities and develops from 4 major structures. THE SEPTUM TRANSVERSUM (most important component) forms the central tendon and is first seen as a thick mesodermal plate cranial to the pericardial cavity between the base of the thoracic cavity and the stalk of the yolk sac.
