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.
Diaphragm is a muscular and tendinous sheath that closes the opening between thorax and abdomen and is pierced by structures that pass between these two regions of the body. The diaphragm is the primary muscle of respiration. It is dome shaped and consists of a peripheral muscular part and central tendinous part.The muscular part arises from the margins of the thoracic opening and gets inserted into the central tendon.diaphragm.penings in the diaphragm: All the structures that pass from the thorax into the abdomen or rise from abdomen into the thorax pass through the diaphragm. For this reason, diaphragm contains numerous openings.
