The most abundant and widely distributed of the tissue types March 1999. It includes fibrous tissues, fat, cartilage, bone, bone marrow, and blood. Mixed connective tissue disease (MCTD) is a rare autoimmune condition; it is often referred to as an overlap disease because the symptoms of MCTD overlap with other connective tissue conditions, including polymyositis, scleroderma and systemic lupus erythematosus (SLE). Below the ectoderm of many animals, connective tissue forms sheets of varying complexity, existing as fine membranes or as complex superficial layers of fibres. Connective tissue. The extracellular matrix is composed of glycosaminoglycans and proteoglycans. The cells sit in a matrix made up of glycoproteins, fibrous proteins and glycosoaminoglycans , which have been secreted by the fibroblasts, and the major component of the matrix, is in fact, water. What is connective tissue? Connective tissue connects, supports, binds, and separates organs and tissues, forming a framework to support body tissues and organs, for structural and metabolic purposes. Most connective tissues are vascularized (except cartilage). Areolar connective tissue has no apparent structure, like layers or rows of cells. The dense irregular connective tissue has a dense woven network of collagen and elastic fibers in a viscous matrix. Connective Tissue. Location. he had a lens dislocation due to a connective tissue disease named Marfan (I think that the name). Connective tissue is a continuous network of structure that binds tissues into their organ shape, supplies them with vessels and ducts and properly fastens the organs within the body cavity as well as binding organs to each other. Connecting Tissues to One Another. The density of these fibers and the presence or absence of certain chemicals make some connective tissues soft and rubbery and others hard and rigid. Collagen fibers are relatively wide and stain a light pink, while elastic fibers are thin and stain dark blue to black.
