Loose Connective Tissue Ground Substance

The pericardium is also composed of connective tissue.
Loose connective tissue ground substance. The amorphous ground substance of connective tissue is a transparent material with the properties of a viscous solution or a highly hydrated thin gel. Loose connective tissue is named so because of the weave and type of its constituent fibers. Its principal constituents are large carbohydrate molecules or complexes of protein and carbohydrate called glycosaminoglycans formerly known as mucopolysaccharides. However the primary tissue composing the heart is cardiac muscle.
The three main types of loose connective fibers include collagenous elastic and reticular fibers. These fibers form an irregular network with spaces between the fibers. The ecm is composed of a moderate amount of ground substance and two main types of protein fibers. Loose areolar connective tissue is the most abundant form of collagenous connective tissue.
Loose connective tissue is characterized by few fibers and cells and a relatively large amount of ground substance. Loose connective tissue lct also called areolar tissue belongs to the category of connective tissue proper. Its cellular content is highly abundant and varied. Fibers form a soft internal skeleton stroma that supports other cell types white blood cells mast cells and macrophages.
For example it forms telae such as the tela submucosa and tela subserosa which connect mucous and serous membranes to the muscular layer. The spaces are filled with ground substance. Heart please be aware that there is connective tissue in the heart. It occurs in small elongated bundles separated by regions that contain ground substance.
Network of reticular fibers in typical loose ground substance reticular cells lie on the network. Lymphoid organs nodes bone marrow and spleen. Blood fluid connective tissue no fibers only ground substance plasma and cells red white and platelets loose connective tissue loose connective tissue is found between many organs where it acts both to absorb shock and bind tissues together. It holds organs in place and attaches epithelial tissue to other underlying tissues.
Loose connective tissue is the most common type of connective tissue in vertebrates. The blood in the heart for example is composed of connective tissue.
