  2. Reticular fiber - Wikipedia

    en.wikipedia.org/wiki/Reticular_fiber

    Reticular fibers, reticular fibres or reticulin is a type of fiber in connective tissue [1] composed of type III collagen secreted by reticular cells. [2] They are mainly composed of reticulin protein and form a network or mesh.

  3. Reticular connective tissue - Wikipedia

    en.wikipedia.org/wiki/Reticular_connective_tissue

    Reticular connective tissue resembles areolar connective tissue, but the only fibers in its matrix are reticular fibers, which form a delicate network along which fibroblasts called reticular cells lie scattered. Although reticular fibers are widely distributed in the body, reticular tissue is limited to certain sites. It forms a labyrinth-like ...

  4. Reticular cell - Wikipedia

    en.wikipedia.org/wiki/Reticular_cell

    Reticular cells provide structural support, since they produce and maintain the thin networks of fibers that are a framework for most lymphoid organs. Reticular cells are found in many organs, including the spleen, lymph nodes and kidneys. They are also found within tissues, such as lymph nodules.

  5. Connective tissue - Wikipedia

    en.wikipedia.org/wiki/Connective_tissue

    Connective tissue is found in between other tissues everywhere in the body, including the nervous system. The three meninges, membranes that envelop the brain and spinal cord, are composed of connective tissue. Most types of connective tissue consists of three main components: elastic and collagen fibers, ground substance, and cells. [2]

  6. Lymph node - Wikipedia

    en.wikipedia.org/wiki/Lymph_node

    Thin reticular fibers (reticulin) of reticular connective tissue form a supporting meshwork inside the node. [5] These reticular cells also form a conduit network within the lymph node that functions as a molecular sieve, to prevent pathogens that enter the lymph node through afferent vessels re-enter the blood stream. [23]

  7. Dense irregular connective tissue - Wikipedia

    en.wikipedia.org/wiki/Dense_irregular_connective...

    This type of connective tissue is found mostly in the reticular layer (or deep layer) of the dermis. [3] It is also in the sclera and in the deeper skin layers. Due to high portions of collagenous fibers, dense irregular connective tissue provides strength, making the skin resistant to tearing by stretching forces from different directions.

  8. Loose connective tissue - Wikipedia

    en.wikipedia.org/wiki/Loose_connective_tissue

    Its fibers run in random directions and are mostly collagenous, but elastic and reticular fibers are also present. Areolar tissue is highly variable in appearance. In many serous membranes, it appears as a loose arrangement of collagenous and elastic fibers, scattered cells of various types; abundant ground substance; numerous

  9. Dermis - Wikipedia

    en.wikipedia.org/wiki/Dermis

    The reticular dermis is the lower layer of the dermis, found under the papillary dermis, composed of dense irregular connective tissue featuring densely-packed collagen fibers. It is the primary location of dermal elastic fibers. [2] The reticular region is usually much thicker than the overlying papillary dermis.
