Dense regular connective tissue composed of collagen fibers arranging in a parallel fashion and are themselves produced and maintained by fibrocytes. Because of the arrangement, dense regular CT can resist pulling in the direction parallel to the fibers (tensile strength) but handle oblique pulling poorly. Moreover, unlike other connective tissues, dense regular CT are poorly vascularized and therefore do not heal well following an injury. It can be found in tendons, ligaments and aponeuroses.
