The type of connective tissue that form tendons, fascia, ligaments and General is structures that receive traction in the direction toward which its Collagen fibers are oriented. These fibers are arranged in a way that is orderly, parallel each other, which provides maximum strength.Tendons in the formation of the fibers is common, parallel each other and fibroblasts ( called tendinocitos in this 41 structure; between fiber and fiber. It also presents the tendon a TC that is dense on the periphery of the same, suffering not so parallel fibers, called epitendon. Finally, around each fascicle of the tendon is observed a tissue called endotendon.In the aponeurosis are Collagen fibers parallel each other, but arranged in layers and disposal orthogonal, i.e., a layer put a 90 ° over the bottom layer.Ligaments do not change the shape of the tendons, with the exception of ligaments of certain parts of the body where more elasticity, as for example the yellow ligament in the vertebral column is required. In these places, the ligaments have a greater amount of elastic fibers, collagen, and not so regular. They are called elastic ligaments.Tissue connective dense Irregularesta present in capsules of lymph nodes, the liver, kidney, intestine thin and dermis. Basically it is part of the capsule of all the organs, with the exception of the pancreas, which is a loose areolar connective tissue. In this dense irregular connective tissue are Collagen fibers arranged in a random and very little ground substance. This provides protection against the excessive stretching of the organs.
