Ischemic Heart Disease Pathology Quiz

Myocardium Composition

• Approximately 23% of the cell volume in myocardium is composed of mitochondria.

Functional Integration

• Intercalated discs in myocardium provide functional integration through intercellular junctions, facilitating communication and coordination between cardiac muscle cells.

Specialized Stimulation System

• The primary function of the specialized stimulation system in myocardium is to regulate the heart's rhythm and ensure effective contraction through electrical impulses.

Artery Types in Myocardium

• Small and medium-sized arteries, known as intramural arteries, are located within the intramural region of the myocardium.

Capillary Network Function

• The rich capillary network in the myocardium primarily functions to supply oxygen and nutrients to cardiac muscle cells and remove metabolic waste products, supporting high energy demands.
