Splenic trabeculae

Splenic Trabeculae are a network of fibrous tissue found within the spleen. They provide structural support to the spleen and help in the distribution of blood vessels.

Anatomy

The spleen is a soft, purplish organ located in the upper left quadrant of the abdomen. It is surrounded by a capsule of dense connective tissue, from which the splenic trabeculae extend into the organ. The trabeculae divide the spleen into numerous compartments, known as splenic pulp.

The splenic trabeculae are composed of collagen fibers and smooth muscle cells. They carry the branches of the splenic artery and vein, and provide a framework for the lymphatic system within the spleen.

Function

The primary function of the splenic trabeculae is to provide structural support to the spleen. They help maintain the shape of the spleen and prevent it from collapsing under its own weight.

In addition, the trabeculae play a crucial role in the distribution of blood within the spleen. They carry the branches of the splenic artery and splenic vein, which supply blood to and drain blood from the spleen, respectively.

The splenic trabeculae also contribute to the function of the spleen in the immune system. They provide a framework for the lymphatic system within the spleen, which plays a key role in the body's defense against infections.

Clinical Significance

Abnormalities in the splenic trabeculae can lead to various health problems. For example, splenomegaly (enlargement of the spleen) can cause the trabeculae to become stretched and thin, which can impair the function of the spleen. In addition, diseases such as sickle cell anemia and lymphoma can cause changes in the structure of the splenic trabeculae.
