Connective tissue is derived from mesenchyme (unlike most epithelial tissue which is derived from ectoderm and endoderm).
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.

  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.
Loose connective tissue or Areolar connective tissue holds organs and epithelia in place, and has a variety of proteinaceous fibers, including collagen and elastin.
Reticular connective tissue is a network of reticular fibers (fine collagen) that form a soft skeleton to support the lymphoid organs (lymph nodes, bone marrow, and spleen.)

 Fibrous connective tissue - Wikipedia, the free encyclopedia
In zootomy, fibrous connective tissue (FCT) is a type of connective tissue which has relatively high tensile strength, due to a relatively high concentration of collagenous fibers.
The cells of fibrous connective tissue are mostly fibroblasts, irregular, branching cells that secrete strong fibrous proteins as an extracellular matrix.
Tendons, which connect muscle to bone, derive their strength from the regular, longitudinal arrangement of bundles of collagen fibers.

 Connective Tissue Massage at Holistic Junction
Connective Tissue Massage finds its foundations from the principles of Rolfing, and is a form of massage that involves massage of tissues (fascia) that protect, support and surround all other parts within the body.
Connective tissue massage focuses primarily on fascial layers (fascia is a specific kind of connective tissue that supports other musculoskeletal systems) - one level at a time.
Connective tissue massage initially lengthens and restores flexibility to the first superficial layer of fascia, then moving on to each individual layer, repeating the same connective tissue massage until each layer is restored to normalcy.

One generalization is that all of the cells of connective tissues derive from embryonic mesenchyme; thus, they are part of an extended family of cells with at least some common characteristics.
Also the epithelium must be connected to the outside, such as the case here with the lumen of the duodenum continuous with that of the stomach, esophagus, pharynx mouth and outside.
Mesenchyme or "fetal connective tissue" is the source of all connective tissues in the adult.

 Connective tissue
The structural role of connective tissue has been overemphasized at the expense of its metabolic support function in the past and the now most authors rather use the term supporting tissue.
Connective tissues are composed of several macromolecules, many of which are also constituents of the lung, the kidney, the walls of blood vessels, the vitreous gel of the eye, and the synovial fluid.
Differences in the connective tissues of bone, skin and cartilage are in part explained by differences in the content of specific components.

 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).

 Hyaluronic Acid: Can it Prevent Premature Aging?
While a number of studies have linked abnormal levels of HA to either connective tissue disorders (CTDs) or conditions common in CTDs, such as premature aging, there are also a number of studies on Pubmed noting associations of high levels of HA to some forms of cancer.
Many of the features of premature aging syndromes and connective tissue disorders are also known to be caused by nutritional deficiencies, and not surprisingly these are often the same nutritional factors that influence the manufacture of hyaluronic acid.
Hyaluronic acid is being used commercially or experimentally to correct a large portion of the problems found in connective tissue disorders such as fractures, eye disorders, poor wound healing and prematurely wrinkled skin.

 ASI - Female Leadership Styles in the 21st-Century Workplace by Prof. Jean Lipman-Blumen   (Site not responding. Last check: 2007-11-01)
"Connective leadership" derives its label from its character of connecting individuals not only to their own tasks and ego drives, but also to those of the group and community that depend upon the accomplishment of mutual goals.
Connective leadership, which connects individuals creatively to their tasks and visions, to one another, to the immediate group and the larger network, empowering others and instilling confidence, represents a crucial set of strategies for success, not only in the workplace, but in our interdependent world community.
Fifth, connective leadership also integrates and creatively revitalizes individualism with a crucial female perspective, that is, seeing the world as a total system of interconnected, uniquely important parts, rather than as independent, competitive, isolated, and unequal entities.

 Stephen's Web ~ by Stephen Downes ~
Numerous instances of such connections occur; where certain of those connections become salient, and are frequently activated through use, they are recognized as forming a distinct entity, producing a distinct type of knowledge.
For, indeed, the mechansism for attaining the reliability of connective knowledge is fundamentally the same as that of attaining reliability in other areas; the promotion of diversity, through the empowering of individual entities, and the reduction in the influence of well-connected entities, is essentially a way of creating extra sets of eyes within the network.
Moreover, as we enter the connected age, we live with remnants of the previous eras, years when connectivity in society was limited, control over perspective maintained by the beneficiaries of scale-free communications networks.

This is how the connective tissue content of meat may be measured with a fiber-optic probe for the on-line detection of tough beef.
It is synthesized by fibroblasts and smooth muscle cells, contributes substantially to the endomysial connective tissues around individual muscle fibers, provides a small fraction of the collagen found in skin and occurs in the large collagen fibers dominated by Type I collagen.
Cells from the vascular system may wander through connective tissues and even compact structures such as tendons have their own lymphatic and vascular supply, something that is not easily seen in an exsanguinated carcass.

In order to understand connective tissue, you must understand its general properties, the extracellular matrix material in which it lies as well as the cell types it contains.
If a connective tissue has plenty of cells within it, it is better at recovering after injury.
If, however, a connective tissue has few cells (and/or blood supply is limited), it is more difficult to repair that connective tissue.

All of these diseases are directly related to mutations in genes, and thus are called "heritable." Some other connective tissue problems are not directly linked to mutations in tissue-building genes, although some people may be genetically predisposed to becoming affected.
Connective tissue is the material between the cells of the body that gives tissues form and strength.
Another NIAMS project is examining gene defects that lead to abnormal elastin, the connective tissue protein that allows arteries, muscles, and other organs to respond in certain ways to movement.
