HEART MUSCLE Meaning and
Definition
-
The term "heart muscle" refers to the specialized muscle tissue that constitutes the walls of the heart, which is responsible for the organ's contraction and subsequent pumping of blood throughout the body. Also known as cardiac muscle or myocardium, the heart muscle is composed of cardiac cells called cardiomyocytes, which possess unique structural and functional properties.
The heart muscle is an involuntary muscle, meaning it contracts and relaxes without conscious control, as it is regulated by the autonomic nervous system. It has a highly coordinated and organized structure, consisting of individual cardiomyocytes that are interconnected to form efficient and synchronized contractions.
The primary function of the heart muscle is to facilitate the circulation of blood. During each contraction, the heart muscle squeezes, forcefully pushing oxygenated blood out of the left ventricle into the aorta, while simultaneously pumping deoxygenated blood from the right ventricle into the pulmonary artery. Upon relaxation, the heart muscle allows blood to flow back into the heart, filling the chambers for the next cycle of contraction.
The heart muscle also requires a constant supply of oxygen and nutrients in order to sustain its own metabolism. Specialized coronary arteries deliver oxygenated blood to the heart muscle, ensuring its vitality and proper function. Consequently, any impairment or damage to the heart muscle can lead to various cardiovascular conditions, such as cardiomyopathies, heart failure, or arrhythmias.

Etymology of HEART MUSCLE
The word "heart" originated from the Old English word "heorte" or "heorte", which is a cognate of the Dutch "hart" and German "Herz". The etymology goes back to the Proto-Germanic word "*hertô" derived from the Proto-Indo-European word "*ḱḗr" which meant "heart" or "belly". This word can also be traced back to the Sanskrit word "hṛd", meaning "heart".
The word "muscle" has a different origin. It stems from the Latin word "musculus", which referred to "a little mouse" because the Romans thought the contracting muscles resembled mice moving under the skin. The Latin term "musculus" eventually came to be used to describe the specific tissues responsible for movement and contraction, including the heart muscle.
