"Crena cordis" is a medical term that refers to a V-shaped cavity found in the wall of the heart. The spelling of this word can be explained using IPA phonetic transcription, where "crena" is pronounced as kɹiːnə and "cordis" is pronounced as kɔːrdis. The V-shaped cavity is located between the right atrium and ventricle of the heart. Proper spelling of medical terms is crucial for effective communication between medical professionals and can prevent confusion and mistakes in diagnosis and treatment.
Crena cordis is a Latin term that translates to "the notch of the heart" in English. It refers to a specific anatomical notch or depression located on the border between the two upper chambers (atria) of the heart. It is situated at the junction of the superior vena cava and the right atrium.
This small and well-defined notch serves as a demarcation point of the atria, separating the right atrium from the more superiorly positioned superior vena cava. It is primarily formed by the inner muscular wall of the right atrium, which curves around the superior vena cava to create this distinctive depression.
The crena cordis is an important anatomical landmark commonly utilized in medical literature and practice. It aids in identifying various heart structures during surgical procedures, electrocardiography assessments, and cardiac imaging techniques.
Additionally, the crena cordis plays a role in understanding the physiology and circulation of the heart. It allows for the regulation of blood flow between the two atria, helping to ensure proper functioning of the cardiac cycle. The notch also provides crucial information regarding the conduction system of the heart, as it is adjacent to the sinoatrial (SA) node, which initiates the electrical impulses that regulate the heart's rhythm.
In summary, crena cordis refers to an anatomical notch located between the atria of the heart. It serves as an important landmark for cardiac procedures and provides insights into the heart's circulation and electrical conduction system.
One of the two furrows on the surface of the heart marking the division of the ventricles; sulcus longitudinalis.
