What is trabeculae carneae?

Trabeculae carneae are muscular ridges or irregular projections found in the inner walls of the heart ventricles (particularly the left ventricle in humans). These structures are formed by the cardiac muscle tissue and serve to increase the surface area of the ventricular walls, allowing for more efficient contraction of the heart muscle.

Trabeculae carneae play a crucial role in the functioning of the heart by helping to maintain a consistent blood flow and pressure within the ventricles. They also help to prevent the formation of blood clots and ensure that the heart chambers are able to contract and relax properly.

The pattern and density of trabeculae carneae can vary between individuals and can be influenced by factors such as age, fitness level, and overall heart health. In some cases, abnormalities in the trabeculae carneae can be associated with certain heart conditions or diseases.

Overall, trabeculae carneae are an important structural feature of the heart that contributes to its function and efficiency in pumping blood throughout the body.
