Prominent chondrocytes found in lacunae, but fine collagen fibers cant be seen. It actually consists of large molecules called glycosoaminoglycans (GAGs) which link together to form even larger molecules called proteoglycans. Collagen fibers have good tensile strength and are therefore important in support. Cards Return to Set Details.

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. Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components: cells, large amounts of ground substance, and protein fibers. Most hyaline cartilage is surrounded by perichondrium, exceptions are: Articular Cartilage in joints and cartilage of epiphyseal plates (bone growth areas).

Embedded in this are our muscles, blood vessels etc. Ground substance is a viscous gel made of water, proteoglycans, glycoproteins and glycosaminoglycans. Fibroblasts are large flat spindle-shaped cells with processes that extend out from the ends of the cell body. Ground substance: the environment that surrounds both cells and fibers of the pulp (Lab Image 2) is rich in proteoglycans, glycoproteins and large amounts of water. Ground substance is composed of varying amounts of water and specialized molecules that help determine how firm or soft the extracellular matrix will be. Patients with anxiety disorders often show heightened amygdala response to anxiety cues. 09/03/2015. matrix: Latin = a female animal used for breeding, womb; refers to ground substance of connective tissue, and nail bed. ground substance - fluid or semi-fluid portion of the matrix Click here to study/print these flashcards.

Groundswell definition is - a broad deep undulation of the ocean caused by an often distant gale or seismic disturbance. The large number of undifferentiated mesenchymal cells (present as perivascular cells ) within the pulp facilitates the recruitment of newly differentiating cells to replace others when they are lost - specifically odontoblasts . Anatomy. We call this free-flowing ground substance plasma. This ground substance is usually a fluid (water), but it can also be mineralized and solid, as in bones. In blood, the ground substance lacks stabilizing macromolecules. Level. Classification. Create your own flash cards! Tendons are part of the connective tissue matrix in the body and collagen is the main component of all connective tissue. 7. These make the ground substance viscous and bind high amounts of water which allows hydration, diffusion of nutrients and nourishing of the tissue. Term. Contains a resilient gel as its ground substance and looks bluish-white and shiny (can stain pink or purple). Level . It holds organs in place and attaches epithelial tissue to other underlying tissues. In simple words, the connective tissue is a group of various cell that interlaced together and connect the various cell and structure of the body. Interstitial fluid (ISF) Nutrients and other substances diffuse between blood capillaries and cells. This fluid quality allows for organs and muscles to glide over each other without friction.
