Trabeculae of spleen

== Trabeculae of Spleen ==

The trabeculae of the spleen are fibrous bands that extend from the capsule into the parenchyma of the spleen. These structures provide a supportive framework for the spleen and play a crucial role in maintaining its shape and integrity.

Structure

The trabeculae are composed of connective tissue and contain collagen fibers, elastic fibers, and smooth muscle cells. They originate from the splenic capsule and penetrate the splenic parenchyma, dividing it into smaller compartments. These compartments are filled with white pulp and red pulp, which are essential for the spleen's immune and hematological functions.

Function

The primary function of the trabeculae is to provide structural support to the spleen. They help maintain the organ's shape and prevent it from collapsing. Additionally, the trabeculae serve as conduits for blood vessels and nerves, facilitating the distribution of blood and innervation throughout the spleen.

Clinical Significance

Damage or disease affecting the trabeculae can compromise the structural integrity of the spleen, potentially leading to conditions such as splenomegaly or splenic rupture. Understanding the anatomy and function of the trabeculae is important for diagnosing and treating splenic disorders.
