Biomedical Instrumentation

what is bio electric potentials

• current produced by muscles

• voltage produced by the cell

• power produced by muscular contraction

• chemical activity of blood

what is resting potential

• uncharged cell

• charged cell

• inner cell positive w.r.t outer

• outer cell positive with respect to inner

What is action potential

• cell inner negative with respect to positive

• cell charged fully

• cell outer negative with respect ti inner

• doing some action by cell

What is depolarisation

• process of changing from resting potential to action potential

• process of changing from action to resting potential

• process of changing from resting and action potential

• none of the above

Define depolarization

• cell remaining in action potential

• cell remaining in resting potential

• cell regains its original state from action potential

• cell regains its original state from resting potential

What is electrodes

• used to measure blood pressure

• used to measure heart rate

• used to measure bioelectric activity

• used to measure temperature

Define types of electrodes

• Microelectrodes, Floating electrodes, Micropipet electrodes

• Microelectrodes, Skinsurface electrodes and needle electrodes

• Metal electrodes, Spray on electrodes, needle electrodes

• Micropipet electrodes, skinsurface electrodes, Floating electrodes

What is the normal value of Blood pressure
