What is the functional importance of the intercalated discs of cardiac muscle? What is the functional importance of the fibrous skeleton of the heart?

Intercalated discs contain anchoring desmosomes that prevent cell separation, and gap junctions that allow ions to travel from cell to cell, transmitting current across the entire heart. The fibrous skeleton acts both as a tendon and an insertion, giving the cardiac cells something to pull or exert their force on.
