Answer;
-Pectinate muscles
Explanation;
-Pectinate muscles are shaped a little like hair, and their function is maxium atrial contraction with minimal muscle mass.The pectinate muscles (musculi pectinati) are parallel ridges in the walls of the atria of the heart. They are so-called because of their resemblance to the teeth of a comb as in pecten.

Anaerobic exercise is one situation that would cause a buildup of lactic acid in human muscle cells. As the cells switched over from aerobic respiration to fermentation in order to produce ATP, lactic acid would be produced in relatively large quantities as a byproduct. This allows NADH and FADH2 electron carriers to be oxidized without the electron transport chain and would allow Glycolysis to continue.
