If the closely packed bundles of fibers are located in one direction, it is called regular; if oriented in multiple directions, it is referred to as irregular. The loose connective tissue (L) of the lamina propria underlies the simple columnar epithelium and consists of many closely packed cells. There are three major categories of dense connective tissue: regular, irregular, and elastic. Dense regular connective tissue fibers are parallel to each other, enhancing tensile strength and resistance to stretching in the direction of the fiber orientations. 7 Interesting Facts about Connective Tissue ...Bones.
