What is the pericardium
The outer most layer of the heart
What does the pericardium contain
Layer of mesothelial cells resting on a thin layer of fibrous connective tissue
What is the epicardium
It is the adipose connective tissue, vessels and nerves
Where is the epicardium found
Found between the pericardium and the myocardium
What is the myocardium
The thickest layer of the heart
What is the myocardium composed of
Specialised cardiac muscle
Striated
Central nuclei
Branching fibres

What do intercalated discs do
