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.
Specifically, NCS measure how well your nerves can send signals to your muscles and the needle EMG measures the electrical activity of your muscles. The NCS and needle EMG form the core of an EMG, however, an EMG can also include a variety of other specialized examinations.
