Tunica Adventitia- fibro elastic CT
Name the four layers of the heart and describe
endocardium- continuous w/ tunica intima, CT, nerves, vessels
myocardium- cardiac muscle
enodmysium- CT
epicardium- inner fibrous( + outer serous
In which layer of the heart tissue are the coronary vessels located?
the inner fibrous epicardium
Describe the conduction path of the heart
SA node to AV node to Bundle of His to bundle branches to Purkinje fibers
The purkinje fibers are located in what layer of heart tissue?
the endocardium
What structure of the heart is made of a tough dense CT base which holds the cardiac muscle and valve rings?
the cardiac skeleton
What type of tissue are valves made of?
made of endocardium covered by endothelium with a core of dense CT
