Telecom consolidation is driven largely by the need for scale efficiencies, made more urgent as telecom players increasingly compete on price. Size and scale give telecom companies a larger geographic coverage plus expanded offerings, which can serve to hedge against a downturn in any specific service segment.
A neck injury may cause damage to the phrenic nerve. Symptoms of a phrenic nerve injury may include difficulty breathing. A pacemaker may be surgically implanted into an individual that has difficulty breathing due to phrenic nerve damage. Physical trauma is the most common cause of damage to phrenic nerves.
The phrenic nerve is a mixed motor/sensory nerve that courses through the neck and thorax to innervate the diaphragm. Arises from the ventral rami of the C3, C4 and C5 nerve roots, part of the cervical plexus.he phrenic nerve is the sole motor supply to each hemidiaphragm. It also provides sensory supply to: 1  diaphragm (except the most peripheral diaphragm, which is supplied by intercostal nerves). 2  mediastinal pleura. 3  pericardium.
