Dense irregular connective tissue stretching forces from different directions. Dense irregular connective tissue also makes up submucosa of the digestive tract, fibrous capsules of joints and lymph nodes, and some types of fascia. Other examples include periosteum and perichondrium of bones, and the tunica albuginea of testis. In the submucosa layer, the fiber bundles course in varying planes allowing the organ to resist excessive stretching and distension. Dense irregular connective tissue Dense irregular connective tissue has fibers that are not arranged in parallel bundles as in dense regular connective tissue. Dense irregular connective tissue consists of mostly collagen fibers. It has less ground substance
Loose connective tissue an extracellular matrix. The cells of this type of tissue are generally separated by quite some distance by a gelatinous substance primarily made up of collagenous and elastic fibers. Loose connective tissue is named based on the weave and type of its constituent fibers. There are three main types of connective tissue fiber: Usually "loose connective tissue" is considered a parent category that includes the mucous connective tissue of the fetus, areolar connective tissue, reticular connective tissue, and adipose tissue. It is a pliable, mesh-like tissue with a fluid matrix and functions to cushion and protect body organs. Fibroblasts are
