A) ECG
B) EEG n
C) MET
D) CT
Correct Answer: B
Solution :
Electroencephalography (EEG) is the graphic representation of the electrical activity of brain cells that are picked up by electrodes placed on the scalp. The neurons of the brain produce electrical impulses which fluctuate rhythmically in specific manner. These neurons conduct four types of waves i.e., alpha waves, beta waves, theta waves and delta waves. Electrocardiography (ECG) is a device which is used to record the electric activity of the heart to detect abn6rmal electric impulses through the muscles and allow diagnosis of cardiac abnormalities. Computed Tomographic scanning (CT scan) is employed to obtain cross-sectional image of internal body structure. It is radiologic technique to obtain clear X-ray images of deep internal structures by focusing on a specific plane of body.
