What is the normal polarity of a myocardial cell during the resting period, which causes the electrical potential in for the cell?
a. positively charged
b. negatively charged
c. outside the cell membrane is negatively charged, inside is positively charged
d. inside the cell membrane is negatively charged, outside is positively charged
Answer: d. inside the cell membrane is negatively charged, outside is positively charged
The normal polarity of a myocardial cell during the resting period, which causes the electrical potential in for the cell, is outside the cell membrane is negatively charged, inside is positively charged. This has brought about the term "polarized cell" for a normal resting myocardial cell.
