Statement-1 :EEG is of immense diagnostic value in the cardiac diseases.
Statement-2 :Defects in cardiac functions can be reflected in changes in the pattern of electrical potentials recorded in the EEG.
-
Solution
An electrocardiogram is the recording of the various events of the cardiac cycle. Defects in cardiac functions or structures are reflected in the ECG. The ECG is,therefore of immense diagnostic value in cardiac diseases. On the other hand, EEG is an index of the brain functions. EEG or electroencephalogram represents the spontaneous electrical activity of the brain as recorded from the electrodes placed on the scalp. EEG wave pattern obtained shows certain characterstic feature of the brain like the frequency amplitude of the signals of brain. Thus any deviation from the normal caused eithery brain disease or change in the physiological state of the brain can be easily detected by EEG.

The accompanying diagram shows three stages in the cardiac cycle –
Which of the following sequence is correct?
Figure shows blood circulation in humans with labels A to D.Select the option which gives correct identification of label and functions of the part:
-
Solution
Artery is blood vessel which receives blood from heart,has elastic thick wall shows jerky movements due to pumping activity of heart. Vein is a blood vessel which carries blood towards the heart, has wider lumen with internal valves where blood flows smoothly and slowly.Blood capillary is a very fine blood vessel which has a single layered wall. Pulmonary veins are the only veins which carry oxygenated blood. (pO2= 95 mm Hg, pCO2= 40 mm Hg)
The figure shows a human blood cell. Identify it and give its characteristics.
-
Solution
Basophils secrete histamine, serotonin, heparin, etc., and are involved in inflammatory reactions.
