Question

Compare striated muscle and unstriated muscle and cardiac muscle.

Answer 1

Answer:

Cardiac muscle cells usually have a single (central) nucleus. The cells are often branched, and are tightly connected by specialised junctions. The region where the ends of the cells are connected to another cell is called an intercalated disc.

The intercalated disc contains gap junctions, adhering junctions and desmosomes.

Gap junctions allow the muscle cells to be electrically coupled, so that they beat in synchrony.
