Let us answer this question and talk about some differences between the cardiac and the skeletal muscle sense.
00:05
First, the most obvious difference between the skeletal muscle and also the cardiac cell or the cardiac muscle is that the skeletal muscle is a voluntary muscle.
00:19
Okay, it means you can decide when to contract your muscle.

Another difference between them is that the skeletal muscle has gap junctions, okay? oh, the skeletal muscle does not have gab junction, while the cardiac muscle has gap junctions.
00:59
Gap junctions are like this...
