Reticular connective tissue Reticular connective tissue Reticular connective tissue is a type of connective tissue with a network of reticular fibers, made of type III collagen ("reticulum" = net or network). Reticular fibers are not unique to reticular connective tissue, but only in this type are they dominant. Reticular fibers are synthesized by special fibroblasts called reticular cells. The fibers are thin branching structures. Reticular connective tissue is found around the kidney, the spleen, and lymph nodes, Peyer's patches as well as in bone marrow. The fibers form a soft skeleton (stroma) to support the lymphoid organs (lymph node stromal cells, red bone
Spongy tissue problem is particularly common, giving soft, white, 'corky' tissue. Spongy tissue is also a type of animal tissue which contains smooth muscles, fibrous tissues, spaces, veins, and arteries. An example is the corpus spongiosum penis. In bone, the spongy tissue is called cancellous tissue. Spongy tissue Spongy tissue is a type of tissue found both in plants and animals. In plants, it is part of the mesophyll, where it forms a layer next to the palisade cells in the leaf. The spongy mesophyll's function is to allow for the interchange of gases (CO2) that are needed for photosynthesis. The spongy
