Medical and Biological Measurements Quiz

To measure EEG, we place electrodes on any muscle and measure the electrical signal.

MRI scan measures blood flow in the brain.

With only two main ECG leads, we can plot the vector cardiograph and measure the axis of the heart.

Mean power frequency represents the statistical mean of the power spectrum of a signal.

Breathing is as a result of the volume and pressure change of the lung inside the thoracic cavity.

During inspiration the pressure inside the lung is positive respect to the atmospheric pressure.

Diaphragm's contraction increases the volume of the thoracic cavity volume by increasing its back-to-front diameter

The compliance of lung is variable and its maximum is around the maximum volume.

The lung compliance is independent of the lung volume.

Lung sounds have much higher frequency components than tracheal breath sounds.
