Creases of the trunk are formed by well-organized collagen bundles in a beehive pattern, attached to the dermis and related to the underlying muscle fascia. The anterior axillary fold has less organized collagen bundles and elastic fiber participation and orientation. The elastic fibers participate in the formation of the collagen network and radiate in a parallel fashion in the reticular dermis and in a perpendicular pattern in the papillary dermis. The skin superior and inferior to the creases lacks such organization of the collagen and elastic fibers and is deposited in a random pattern.

Reconstruction of these features of the skin has an integral role in the function and form of the body and requires sufficient understanding of their structural (skin) anatomy as well as their anatomical and functional interactions with adjacent ligamentous structures and soft tissues.
