  Connective tissue - Wikipedia, the free encyclopedia
Connective tissue is any type of biological tissue with an extensive extracellular matrix and often serves to support, bind together, and protect organs.
Dense connective tissue or Fibrous connective tissue forms ligaments and tendons.
Loose connective tissue or Areolar connective tissue holds organs and epithelia in place, and has a variety of proteinaceous fibers, including collagen and elastin.

Connective tissue is characterized by an abundance of intercellular substance, or matrix.
Connective tissue is composed of three structural entities namely an amorphous ground substance, fibers and cells.

Fibrous dysplasia is a chronic disorder of the skeleton that causes expansion of one or more bones due to abnormal development of the fibrous, or connective, tissue within the bone.
Recent studies indicate that fibrous dysplasia may be caused by a chemical abnormality in a protein in the bone that leads to an overgrowth of bone cells that produce fibrous tissue.
Surgery is recommended for fibrous dysplasia to relieve intractable bone pain, to improve mobility that may be impaired due to skeletal deformity, to facilitate the healing of fractures, to relieve local pressure on the spinal cord, spinal nerves, or brain, and to treat the unusual complication of bone sarcoma.

 SIU SOM Histology INTRO
Connective tissue may be distinguished as either loose or dense, depending on the proportion of fibers.
Dense elastic connective tissue is found wherever the elasticity of elastin is of paramount importance, as in the ligamentum flavum (flavum refers to the yellow color conferred by the elastin) and the aorta.
The major determinant of the mechanical properties of most connective tissue is the extracellular matrix which is secreted by the cells within it (fibroblasts in ordinary connective tissue, osteoblasts and chondroblasts in bone and cartilage respectively).

 Blue Histology - Connective Tissues
Connective tissue cells are usually divided into two groups based on their ability to move within the connective tissue.
There are two types of adipose tissue, which derive their names from the colour of the tissue (white or brown) and/or the number of lipid droplets found in the adipocytes.
Brown adipose thissue is often located in the connective tissue close to the renal hilus or in the renal sinus of sections which contain the entire kidney of small laboratory animals.

Fibrous dysplasia is a developmental dysplastic disorder of bone in which immature woven bone is formed directly from abnormal fibrous connective tissue.
At a fundamental level, fibrous dysplasia appears to be either a disorder of postnatal cancellous bone maintenance in which bone undergoing physiologic remodeling is replaced by an abnormal proliferation of fibrous tissue or a developmental abnormality of the bone-forming mesenchyme.
At the molecular level, fibrous dysplasia is caused by sporadic mutation of the GNAS1 gene that encodes the alpha subunit of the stimulatory G protein (G1).

 Connective Tissue
As was true for loose connective tissue, the dense and skeletal connective tissues involve more than just cells; it is the non-living extracellular substances which determine the nature and function of the tissue.
This type of dense regular connective tissue is found in the tendon, which connects muscles to bones or cartilage (Tendon 1).
Since bony tissue has no flexibility, the connective tissue must provide it and therefore elastic fibers are now found in the matrix; collagen is also present to provide tensile strength (Ligament 1).

Connective tissue is diversified in function and may be divided into four categories according to the type of matrix.

 Loose Fibrous Connective Tissue   (Site not responding. Last check: 2007-10-21)
Collagen, an albuminoid protein, is by far and away the most abundant structural protein in the body.
This particular tissue sample is called "loose" because of the relatively low number of fibers and the "large" amount of space between the fibers [the intercellular matrix] and the cellular elements of the tissue [that produce the matrix].
Loose fibrous connective tissue "grades" into dense fibrous connective tissue as the number of fibers increases and the spaces in the tissue decrease.
