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).
EMGs can detect abnormal muscle electrical activity in many diseases and conditions, including inflammation of muscles, pinched nerves, damage to nerves in the arms and legs, disc herniation, and degenerative diseases such as muscular dystrophy, Lou Gehrig's disease and Myesthenia gravis, among others.
An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction. Nerve conduction studies measure how well and how fast the nerves can send electrical signals.Nerves control the muscles in the body with electrical signals called impulses.These impulses make the muscles react in specific ways. Nerve and muscle problems cause the muscles to react in abnormal ways.If you have leg pain or numbness, you may have these tests to find out how much your nerves are being affected.n EMG is done to: 1  Find diseases that damage muscle tissue, nerves, or the junctions between nerve and muscle. 2  Find the cause of weakness, paralysis, or muscle twitching.
