Biomes. The two main types of biome are terrestrial (land-based) and aquatic (water-based). The easiest to discuss are the terrestrial biomes since they have a more definite boundary. The different climates of the Earth are governed by their average annual precipitation and temperature.
An electrocardiogram (ECG or EKG) test. An electrocardiogram (ECG or EKG) is a routine test that is used to look at the electrical activity of the heartbeat. An electrocardiogram can tell your doctor a lot about your heart and how it is working.
Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). Motor neurons transmit electrical signals that cause muscles to contract.An EMG translates these signals into graphs, sounds or numerical values that a specialist interprets.n EMG uses tiny devices called electrodes to transmit or detect electrical signals. During a needle EMG, a needle electrode inserted directly into a muscle records the electrical activity in that muscle.
