Verified step by step guidance

Understand the structure of a lymph node: A lymph node is a small, bean-shaped structure that is part of the body's immune system. It contains lymphatic tissue and is involved in filtering lymph fluid.

Identify the components of a lymph node: Key components include the cortex, medulla, lymph sinuses, trabeculae, lymph follicles, and medullary cords.

Define lymph sinuses: These are large lymph capillaries within the lymph node that are spanned by crisscrossing reticular fibers. They play a crucial role in filtering lymph fluid as it passes through the node.

Differentiate between the options: Trabeculae are connective tissue structures that extend into the lymph node, lymph follicles are clusters of lymphocytes, and medullary cords are strands of lymphatic tissue in the medulla.

Conclude that the large lymph capillaries spanned by reticular fibers are known as lymph sinuses, as they match the description provided in the problem.
