What are the extensions of the capsule into the body of a lymphatic organ called?

• A. Tebeculae
• B. Extensions
• C. Filaments
• D. Striae

Answer: (A)

The correct term for the extensions of the capsule into the body of a lymphatic organ is "trabeculae." Trabeculae are thin, branching structures that create a framework within the organ, helping to support its structure and providing pathways for blood vessels and lymphatics. In lymphatic organs, such as lymph nodes and the spleen, trabeculae play a crucial role in maintaining the organ's architecture and facilitating the organization of lymphatic tissue, allowing for efficient immune responses and filtering of lymph. This structural feature is essential for the proper functioning of lymphatic organs, aiding in the organization and localization of cells involved in the immune system.
