Like all tissue types, it consists of cells surrounded by a compartment of fluid called the extracellular matrix (ECM). It is composed of proteoglycans and glycosaminoglycans. It is transparent or translucent and viscous in composition; the main chemical components of ground substance are large carbohydrates and proteins known as acid … It consists of a meshwork of collagen, elastic fibres and reticular fibres with many connective tissue cells in between the meshwork of fibres. Answer: a. Connective tissue consists of cells and extracellular fibers in a ground substance and tissue fluid. The hyaluronic acid predominate in loose connective tissue, vitreous humor, synovial fluid and umbilical cords. T he Connective tissue proper contains several types of cells and a variable amount of extracellular matrix made up of fibers and ground substance (Figure 1). Marfan Syndrome is a genetic disorder of the connective tissue. Ground substance is a gel-like material that fills the spaces between connective tissue cells. Areolar tissue is a connective tissue, that takes part in the structural framework of the body. • 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. The material in which the fibers and cells are embedded is called ground substance - a gel composed primarily of glycosaminoglycans (GAGs). This cell makes the fibers found in nearly all of the connective tissues. Fibroblasts, plasma cells, adipocytes, mast cells and macrophages are the major cells of the areolar tissue.

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 one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. c. Tissue fluid d. Ground substance e. None of the above; all of the above are seen with connective tissue. 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. Connective tissue proper includes loose connective tissue and dense connective tissue. This tissue is found during the body under the skin and linking organs and other tissues. It is composed of proteoglycans and cell adhesion proteins that allow the connective tissue to act as glue for the cells to attach to the matrix. The amorphous ground substance of the connective tissue is a transparent material with properties of a viscous solution.

Its principal constituents are large carbohydrate molecules or complexes of protein and carbohydrate, called as glycosaminoglycans or mucopolysaccharides (like hyaluronic acid). Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. The ground substance includes two major groups: Non-sulfated glycosaminoglycans (hyaluronic acid) The hyaluronic acid consists of long molecule that form a network whose spaces are filled with tissue fluid forming gel-like material. fibers and ground substance Choose which tissue would line the uterine (fallopian) tubes and function as a "conveyer belt" to help move a fertilized egg towards the uterus. (E) Mucoid Connective Tissue: In addition to above mentioned connective tissues, mucoid tissue occurs as a foetal or embryonic connective tissue. Areolar Connective Tissue Areolar connective tissue A variety of connective tissue consisting of a gel-like matrix combining strands of protein fibers (collagen and elastin) and so cells as fibroblasts, mast cells, macrophages, and fat cells. The pubic symphysis and intervertebral discs are composed of this type of connective tissue. 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. The amorphous ground substance of connective tissue is a transparent material with the properties of a viscous solution or a highly hydrated thin gel. 19. Functions: The pigmented connective tissue gives colour to the structures. Connective tissue is classified into two subtypes which are soft and specialized connective tissue. Ground substance is active in the development, movement, and proliferation of tissues, as well as their metabolism. This tissue is widespread throughout the body.

It is a mixture of glycoproteins, glycoaminoglycans (such as hyaluronic acid), and proteoglycans. The connective tissues are composed of two components: cells and 12. Within connective tissue, the cells and fibers are embedded in the ground substance. The matrix is composed of fibers, ground substance and tissue fluid. Its principal constituents are large carbohydrate molecules or complexes of protein and carbohydrate, called glycosaminoglycans (formerly known as mucopolysaccharides). Connective tissue is characterized by an abundant extracellular matrix surrounding cells. As may be obvious from its name, one of the major functions of connective tissue is to connect tissues and organs. Another way to prevent getting this page in the future is to use Privacy Pass. Which tissue contains a calcified ground substance and is specialized for structural support? Both tissues have a variety of cell types and protein fibers suspended in a viscous ground substance. It fills spaces between organs (Figure 2), for example between the skin and muscles, and surrounds blood vessels, nerves and several organs. Pigmented connective tissue is present in the choroid, ciliary body and iris of the eye and dermis of the human skin. 14. Connective tissue that provides support and framework for the body consists of fibrous proteins and nonfibrous ground substance in varying proportions depending on their functions. Connective tissue is the most widely distributed of the primary tissues. Hyaluronic sulfate and chondroitin sulfate are two examples. Please enable Cookies and reload the page. The matrix is what provides connective tissue with nutrients, and also provides unique characteristics to the type of tissue it is present in. • Additionally, cells use it for support, water storage, binding, and a medium for intercellular exchange (especially between blood cells and other types of cells). Collagen, which is the most abundant protein, constitutes about one-third of all body protein. All connective tissue consists of three main components: fibers (elastic and collagenous fibers), ground sub… bone connective tissue: Which of the following is not a characteristic of Areolar connective tissue? Ground substance is an amorphous gel-like substance in the extracellular space that contains all components of the extracellular matrix (ECM) except for fibrous materials such as collagen and elastin. There are three major types of connective tissue: reticular, loose, and dense. Connective tissue is the tissue that connects, separates and supports all other types of tissues in the body. It actually consists of large molecules called glycosoaminoglycans (GAGs) which link together to form even larger molecules called proteoglycans. Ground substance definition, the homogeneous substance in which the fibers and cells of connective tissue are embedded. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Watch this video to find out the specific mechanical property imparted to a connective tissue by its GAGs (3:03) What is the principal fibrillar component of the extracellular matrix? 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. The ground substance is composed of an organic substance (usually a protein) and an inorganic substance (usually a mineral or water). 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. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. Synonym (s): substantia fundamentalis Farlex Partner Medical Dictionary © Farlex 2012 It develops from the mesoderm. It consists of cells, fibers & ground substances.
