- Describe the elements that make aged skin more susceptible to infection.arrow_forwardA 60-year-old man presents with a skin lesion on his face, which has been increasing in size for the past 6 months. He has been a farmer by occupation. His past medical history is unremarkable. A biopsy of the lesion shows nests of atypical deeply basophilic cells extending from the overlying epidermis into the papillary dermis. The nests show peripheral palisading of the cells with haphazard arrangement in the center. Which of the following descriptions of gross appearance corelate to the microscopic findings seen in this lesion? Answers A - E A Pearly nodule with telangiectasia B Purple, pruritic, and polygonal lesion C Rough sandpaper consistency lesion D Round flat, coin like waxy plaque E Salmon colored plaque with silvery white scales Oarrow_forwardThe following descriptions of superficial burns are correct except( ) A) Include first degree and superficial second degree burns B) Wet, pink and blistered C) Blanches with pressure and painful D) Slow healing with hypertrophic scar and contracture E) Sufficient epithelial appendages could improve the healingarrow_forward
- Which of the following statements about plaque psoriasis is true? a)the disease lesion only occurs after the skin is physically wounded b)altered CCN function is reflected by increased macrophages , mast cells and dendritic cells in the dermal layer c)in considering the 7 outputs to health and wellness, psoriasis only appears to negatively impact the "physical" d)in psoriasis, the keratinocytes do not divide rapidly enough to maintain skin structurearrow_forwardWhat feature of the skin creates a physical barrier to microbial invasion? Group of answer choices The outer layers are composed of cells full of protein which forms NETs to trap microbes until they are shed. The surface is constantly patrolled by phagocytic cells. The outer layers are dead cells, tightly linked together, and are frequently shed. All of these mechanisms can provide defense against microbial invaders. The oil secreted onto the surface of the skin traps microbes, preventing penetration. The fine hairs move microbes to mucous membranes for phagocytosis.arrow_forwardNonhealing wounds on the surface of the body are often extremely difficult to manage, in part because the microbial cause of the lack of healing is often extremely difficult to identify. Create a list of 4 reasons this might be the case.arrow_forward
