Light micrograph of cardiac muscle & fatty disease

Coloured SEM of healthy heart muscle fibres
Heart muscle. Coloured scanning electron micrograph (SEM) of healthy heart (cardiac) muscle fibres (green). Mitochondria (red) supply the muscle cells with energy

Light micrograph of normal heart (cardiac) muscle
Heart muscle. Light micrograph of healthy heart (cardiac) muscle, seen in longitudinal section. Bundles of muscle fibres are stained red, running diagonally from upper right to lower left

False-colour TEM of striated cardiac muscle
False-colour transmission electron micrograph of a longitudinal section through striated cardiac muscle. Cardiac muscle, unlike skeletal muscle, is composed of seperate cellular elements

Aortic aneurysm. Artwork from Jean Cruveilhiers medical textbook Anatomie pathalogique du corps humain, published 1835. The two large illustrations are views of an aortic aneurysm (brown, centre)

Right-sided heart failure, artwork
Artwork of right-sided heart failure showing damaged heart muscle (brown, lower centre) weakening the power of both the left and right ventricles to pump blood (red arrows) around the body

Left-sided heart failure, artwork
Artwork of left-sided heart failure showing damaged heart muscle (brown, lower centre) weakening the power of the left ventricle to pump blood (red arrows) around the body

Coronary arteries, artwork
Artwork showing the heart and the coronary arteries (red) which supply the heart muscle with blood

Damaged cardiac tissue, artwork
Damaged cardiac tissue. Artwork of damaged heart fibres and cells in heart muscle tissue (myocardium). This can occur due to reduced blood supply (ischaemia)

The heart muscle, also known as cardiac muscle, is a remarkable organ that plays a vital role in our body's functioning. A posterior view of a normal heart and its arteries reveals the intricate network responsible for pumping blood throughout the body. In a cross-section of this incredible muscle, we witness its complex structure and organization. Under the light microscope, we can observe the unique characteristics of cardiac muscle fibers. This microscopic view showcases both healthy tissue and fatty disease, highlighting the importance of maintaining cardiovascular health. Similarly, a colored scanning electron micrograph unveils an up-close look at vibrant and robust heart muscle fibers. Further exploration through microscopy allows us to delve into the world of striated cardiac muscles with false-color transmission electron microscopy. This technique provides valuable insights into their composition and function. However, not all conditions affecting the heart are positive. An image depicting an aortic aneurysm reminds us that certain ailments can pose serious threats to our cardiovascular system. Artwork representing right-sided and left-sided heart failure serves as poignant reminders of how crucial it is to care for our hearts diligently. Artistic renderings showcasing coronary arteries emphasize their significance in supplying oxygen-rich blood to every part of our bodies. Conversely, artwork portraying damaged cardiac tissue serves as a stark reminder that neglecting cardiovascular health can have dire consequences. Exploring various aspects related to heart muscles offers invaluable knowledge about their structure, function, diseases they may encounter like fatty disease or even more severe conditions such as right-sided or left-sided heart failure or damage due to factors like aneurysms or other complications related to coronary arteries.
