The subsections of the dermis are the papillose layer and the merged layer . The papillary layer contains the capillaries , sensory neurons and lymphatics that supply the skin s surface (Martini 161 . The reticular layer is a vast vane of dense unsmooth connector tissue containing both flexible fibers and collagen (Martini 161The presence of collagen and elastic fibers give the skin with strength and catch . Collagen fibers are good and stand fast stretching . However , collagen change form and twists easily . expandible fibers drop out stretching and recoil to its reliable length (Martini 162 . They both provide flexibility but interrupt damage to the tissue (Martini 162The hypodermic layers are connective tissue fibers that are determined in the...If you want to get a full essay, found it on our website: Ordercustompaper.com
