CHORDA TENDINAE Meaning and
Definition
-
Chorda Tendinae, also known as the heart strings, are specialized rope-like fibrous cords found in the heart. These tendons are anatomical structures that play a crucial role in the functioning of the heart valves, particularly the atrioventricular valves, also known as the mitral and tricuspid valves.
The Chorda Tendinae are composed mainly of collagen fibers and are attached at one end to the papillary muscles, which are small, mound-like structures located within the ventricles of the heart. The other end of the Chorda Tendinae is connected to the valve leaflets, specifically the free edges of these leaflets.
The primary function of the Chorda Tendinae is to prevent the inversion or prolapse of the valve leaflets during heart contraction. When the ventricles contract, pressure is applied to the blood, pushing it against the closed valve leaflets. This pressure can create a force that attempts to invert or push the leaflets into the atria. However, the Chorda Tendinae, along with other supporting structures, prevent this by providing tethering and stability to the valve leaflets. They do so by pulling the leaflets downwards and inwards towards the ventricles, ensuring a proper closure of the valves and preventing the backflow of blood.
In conclusion, the Chorda Tendinae are fibrous cords that connect the valve leaflets to the papillary muscles in the heart. They play a critical role in maintaining the integrity and proper functioning of the heart valves, preventing the regurgitation of blood during contraction.

Etymology of CHORDA TENDINAE
The word "Chorda Tendinae" comes from Latin. "Chorda" translates to "cord" or "rope", while "Tendinae" translates to "tendons". Therefore, "Chorda Tendinae" can be understood as "tendinous cords" or "tendinous ropes". This term is commonly used in medical contexts to refer to the tendons that attach the papillary muscles in the heart to the atrioventricular valves (mitral and tricuspid valves).
