Loose, or areolar, connective tissue is composed of all three of the above fibers; it supports most of the organs in the body and is widely distributed under the skin. the amorphous material in which structural elements occur; in connective tissue, it is composed of proteoglycans, glycoproteins, glycosaminoglycans, plasma constituents, metabolites, water, and ions present between cells and fibers. Fibroblasts, plasma cells, adipocytes, mast cells and macrophages are the major cells of the areolar tissue. There are three major types of connective tissue: reticular, loose, and dense.

Dense connective tissue is reinforced by bundles of fibers … The ground substance found in connective tissue is basically a network of macromolecules in a hydrophilic complex (glycosaminoglycans and proteoglycans) and glycoproteins that are the ones that help stabilize the extracellular matrix. Last modified September 4, 2019, Your email address will not be published. The principal cell of connective tissues is the fibroblast, an immature connective tissue cell that has not yet differentiated. However connective tissue differs from other types in that its cells are loosely, rather than tightly, packed within the ECM. It is a mixture of glycoproteins, glycoaminoglycans (such as hyaluronic acid), and proteoglycans. The matrix is what provides connective tissue with nutrients, and also provides unique characteristics to the type of tissue it is present in. Ground substance Ground substance may be fluid, gel, or solid, and, except for blood, is secreted by the cells of the connective tissue: Cell adhesion proteins hold the connective tissue together. It is most clearly seen in cartilage, in the vitreous humour of the eye, and in the Wharton’s jelly of the umbilical cord.

The type of connective tissue in which cells and ground substance are the predominant components is called 13. It consists of a meshwork of collagen, elastic fibres and reticular fibres with many connective tissue cells in between the meshwork of fibres. The amorphous ground substance of the connective tissue is a transparent material with properties of a viscous solution. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue.

Connective tissue is the tissue that connects, separates and supports all other types of tissues in the body. It develops from the mesoderm. Collagen, which is the most abundant protein, constitutes about one-third of all body protein. Connective tissue is one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. It fills spaces between organs (Figure 2), for example between the skin and muscles, and surrounds blood vessels, nerves and several organs. 19. connective tissue [kō-nek´tiv] a fibrous type of body tissue with varied functions; it supports and connects internal organs, forms bones and the walls of blood vessels, attaches muscles to bones, and replaces tissues of other types following injury. • It is transparent, colourless, and fills the spaces between fibres and cells. Connective tissue binds structures together, provides support and protection, fills spaces, produces blood cells, and stores fat.The body uses this stored fat for energy, insulation, and organ protection.

Your IP: 68.171.212.2 The connective tissues are composed of two components: cells and 12. Both tissues have a variety of cell types and protein fibers suspended in a viscous ground substance. As may be obvious from its name, one of the major functions of connective tissue is to connect tissues and organs. This cell makes the fibers found in nearly all of the connective tissues. Additionally, cells use it for support, water storage, binding, and a medium for intercellular exchange (especially between blood cells and other types of cells).
