Q.1 What is a Barometer ?
A.1 It is an instrument use to measure Atmospheric or Air Pressure.
Q.2 What is a Lactometer ?
A.2 It is an instrument use to measure Density of Milk.
Q.3 What is an Ammeter ?
A.3 It is an instrument use to measure Strength of Electric Current in Ampere.
Q.4 What is a Galvanometer ?
A.4 It is very sensitive instrument that is it can measure Electric Current of very low Strength.
Q.5 What is a Viscometer ?
A.5 It is an instrument use to measure Viscosity of a Liquid.
Q.6 What is a Pedometer ?
A.6 It is an instrument use to measure Distance covered by a Human being. Usually it is tied to the leg.
Q.7 What is a Calorimeter ?
A.7 It is an instrument use to measure energy absorb or evolve by human body.
Q.8 What do you mean by ECG describe briefly ?
A.8 The full form of ECG is ElectroCardioGraph. As the Cardiac impulse passes through the heart, electrical currents spread into the tissues surrounding the heart, and a small proportion of these spreads all the way to the surface of the body. If electrodes are placed on the skin on opposite sides of the heart electrical potentials generated by these currents can be recorded, this recording is known as an ElectroCardioGraph.
Most important organ of a human body is the heart. ECG is being successfully used for diagnosing various heart diseases.
Q.9 What do you mean by Pace Maker ?
A.9 To regulate the heart beats an electronic instrument known as ‘’Peace Maker‘’ is commonly transplanted.
Q.10 What do u mean by EEG describe briefly ?
A.10 The full form of EEG is Electro-En-cephaloGraph. It is possible to record electric activity of the brain using a machine called an Electro-en-cephalograph. Electrodes, held in contact with the scalp by wax or tape., pick up electrical activity which is amplified and recorded. These brain waves tell us little about how the brain works, but they are important in the diagnosis of brain diseases for example, Epilepsy. It is now possible to analyze the frequency of abnormal waves by computer, and this provides a much surer way of diagnosing disorders of the brain.
Q.11 What do you mean by MRI ?
A.11 The full form of MRI is Magnetic Resonance Imaging. The MRI technique avoid the harmful effects of the ionizing radiation caused by the current prevailing techniques.
Q.12 What do you mean by C.T.Scan ?
A.12 Computerized Tomography (CT) is X-ray or gamma ray photography of a selected plane in the showing anatomical details clearly.C.T. combines an accumulation of radiation data with the advantage of its rapid analysis by computer. It also can reveal the damage from a stroke buried deep beneath the skull and differentiates between the grey and the white matter of the brain. The potential of the new technique is astonishing as it promises to reveal not only the cellular structure of the body, but its vivo chemistry as well.
Q.13 What do u mean by Angiography ?
A.13 Demonstration of physiology of heart is called Angiography. Angiograms (X-ray pictures) show the flow of blood through the vessels of the heart. It point out the choked area of coronary arteries where flow of the blood is restricted. These vessels are dilated by angioplasty or bypass vessels are transplanted.
