Brief Introduction to Connective tissue Connective tissues are found throughout the whole body, in fact they make up much of the body.Connective tissue "are the most abundant type of tissue by weight." In vertebrates, the most common type of connective tissue is loose connective tissue. ; Skin It is composed of variety of cells, fibre (non-living products of cell) and semi-solid matrix between cells. As the name implies, connective tissues often bind other organs together, hold organs in place, cushion them, and fill space.

Connective (supporting) tissue may be a voluminous, strong, yet elastic sort of tissue with significant physical body roles. They are highly refractile, wavy, and thinner than collagens. Loose connective tissue is named so because of the "weave" and type of its constituent fibers. (f) Connective tissue proper: dense connective tissue, elastic Description: Dense regular connective tissue containing a high proportion of elastic fibers. Under electron microscopy they consist of two components, the central amorphous constituent (elastin) and the microfibrillar component. Your history and physical exam will determine your treatment.
