Question 12

What is the functional significance of large areas of cardiac muscle being electrically coupled to form a single functional syncytium?

Accepted Answer

A)  Because they form a syncytium, cardiac muscles can contract on their own. 
B)  Because they form a syncytium, muscle cells can pass an action potential along a large area of the heart wall, stimulating contraction in each muscle fiber of the syncytium. 
C)  Because they form a syncytium, muscle cells cannot summate contraction to produce tetanus and thus not fatigue. 
D)  Because they form a syncytium, cardiac muscle cells can pass an action potential by way of internodal bundles contracting both atrial chambers. 
A)  Because they form a syncytium, cardiac muscles can contract on their own.
