What is connective tissue? It is the scaffold that gives our body shape. You might think that this would make it tougher to identify. 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). Connective tissue connects, supports, binds, and separates organs and tissues, forming a framework to support body tissues and organs, for structural and metabolic purposes. Loose connective tissue is rich in blood and lymph because of the numerous vessels that run through it. Epithelial Tissue: Epithelial tissue is found in the skin, glands, organs, mucous membranes, and organs like kidney and lungs. These are: Areolar Connective Tissue; Adipose Tissue; Dense Irregular Tissue Connective Tissue: Connective tissue is encompassed of blood capillaries which absorb nutrients. See more. Connective tissue is comprised of 2 major protein compounds, collagen and elastin. General connective tissue is either loose, or dense, depending on the arrangement of the fibres. A connective tissue disease is any disease that affects the parts of the body that connect the structures of the body together.

Compared with most other kinds of tissue, connective tissue has few cells. Epithelial Tissue: Epithelial tissue is found in the skin, glands, organs, mucous membranes, and organs like kidney and lungs. Then there are those sheets of white fibrous tissue, called silverskin, that surround whole muscles. Tissue that connects and binds organs/parts or other tissues to maintain their relative position and furnish support and security to the body is called connective tissue (C.T.) Connective tissue (CT) is a one of the four main classes of tissues. Tissue arising chiefly from the embryonic mesoderm that is characterized by a highly vascular matrix and includes collagenous, elastic, and reticular fibers, adipose tissue, cartilage, and bone. Loose Connective Tissue. Dense connective tissue is found in joint capsules, muscle fascia, and the dermis layer of skin. It forms the supporting and connecting structures of the body. It holds organs in place and attaches epithelial tissue to other underlying tissues. Connective tissue consists mainly of long fibers embedded in noncellular matter, the ground substance. 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.

It is derived from the mesenchyme, and this in turn from the mesoderm. The fibers contain a protein called. ), sometimes firm (Cartilage), sometimes hard as stone (bone). Connective tissues are made up of two proteins: collagen and elastin. Connective tissues bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage. Connective tissue diseases due to an autoimmune condition are more common in people who have a combination of genes that increase the chance that they come down with the disease (usually as adults). Connective tissue doesn’t just stop at the musculus, it surrounds every single organ in the body. Irregularly arranged connective tissue with fibers that are irregularly interwoven may be loose (areolar) or dense. Unlike epithelial tissue , which has cells that are closely packed together, connective tissue typically has cells scattered throughout an extracellular matrix of fibrous proteins and glycoproteins attached to a basement membrane.
