yes, is would be painful due to damage to the der-
mis layer. not all the sensory recep-

Use this picture to compare the tissue structure in the papillary and reticular layers of the dermis. Which of the following best describes your observations?
Multiple Choice
The papillary layer is a thick layer of tightly packed dead skin cells, while the reticular layer is much thinner and more fragile.
The papillary layer is dominated by large, empty-looking cells, while the reticular layer is made of a loose network of fibers infiltrated with white blood cells.
Both layers consist of a loose arrangement of thin, branching fibers in abundant ground substance.
Both layers contain packed, parallel fibers, but the papillary dermis is thicker and much denser.
The reticular layer is thicker and more fibrous. The papillary layer is a thinner zone of more loosely organized tissue containing many "wandering" white blood cells.

How does the structure of the reticular dermis relate to its functional properties?
Multiple Choice
Bundles of densely packed collagen fibers help the skin withstand stretching in many different directions.
The clear, glassy matrix provides cushioning and support.
The loosely organized tissue allows the diffusion of nutrients and the movement of white blood cells between the dermis and the avascular epidermis.
Multiple layers of large, round adipocytes store fat.
The loose network of branching reticular fibers provides a scaffolding to help store large numbers of white blood cells.
