Dermis, thick skin,-low mag.
The dermis is composed of a papillary and a reticular layer. The papillary layer, more cellular and composed of finer collagenous fibers, forms the dermal papillae. The deeper reticular layer has less cells and coarser collagen bundles. Its deepest fibers merge with the looser, fat-filled hypodermis, not shown here. Together the dermis and hypodermis support sweat glands, sebaceous glands and hairs.
