Reticular connective tissue

Reticular connective tissue is a type of connective tissue that consists of a network of reticular fibers (fine type III collagen), which form a soft skeleton to support the lymphoid organs (lymph nodes, red bone marrow, and spleen).

Etymology

The term "reticular" is derived from the Latin word "reticulum" which means "little net". This is in reference to the network-like structure of the tissue.

Structure

Reticular connective tissue is characterized by a network of reticular fibers, which are composed of type III collagen. These fibers are not as thick as type I collagen fibers found in other types of connective tissue, and they form a mesh-like structure. This tissue also contains reticular cells, which are a type of fibroblast that produce the reticular fibers.

Function

The primary function of reticular connective tissue is to provide a supportive framework for the lymphoid organs. This includes the lymph nodes, red bone marrow, and spleen. The reticular fibers form a soft skeleton, or stroma, that supports the parenchyma, or functional part, of these organs.

Clinical significance

Abnormalities in the reticular connective tissue can lead to a variety of medical conditions. For example, a decrease in the number of reticular fibers can lead to a weakening of the tissue and potentially to organ damage. On the other hand, an increase in the number of reticular fibers, known as fibrosis, can lead to the hardening of the tissue and can interfere with the function of the organ.
