In a Presidential System, the head of state and head of government tends to be the same person. In a Parliamentary System, minority groups can form third, fourth, and fifth parties and have much more influence in government than in a Presidential System where third parties are marginalized (many complexities here).
Electromyography (EMG) uses small needle electrodes to measure the electrical currents in a muscle as it contracts. While an EMG canât definitively diagnose metabolic disease, it can be used to rule out a number of other types of neuromuscular disease that cause similar patterns of weakness.
An EMG is done to: 1  Find diseases that damage muscle tissue, nerves, or the junctions between nerve and muscle. 2  These problems may include a herniated disc, amyotrophic lateral sclerosis (ALS), or myasthenia gravis (MG).
