The action potential is a sudden positive shift in the cardiomyocyte's cellular membrane potential, termed depolarization. Depolarization not only initiates contraction within the affected cardiomyocyte (Described in Cardiac Excitation-Contraction Coupling), but also initiates depolarization of adjacent cardiomyocytes.
Polar Coordinates The coordinate system which depicts the points from the pole to the certain distance at a particular angle is known as âpolar coordinatesâ. The positive horizontal axis in which that particular angle rotates is named as âpolar axisâ.
What does the math term coordinate mean? In the Cartesian coordinate system, a point represents a position in a two-dimensional space or plane. This means that that point has an x-value and a y-value. This is written â¦ as (x,y) and the entire paranthesis is the coordinate. Examples of coordinates: (3,6) and (-2, 12).
