Before we move on to some new topics about the skin, let's take a moment to reflect on our discussions in our last class meeting. Feel free to look back at your notes or the Zoom recording of the last meeting to refresh your memory!
Some sort of disease, injury, or infection has afflicted someone’s skin! Your job is to figure out what’s going on and show your evidence for conclusion.
Clues
Keratinocyte: Desmosomes disrupted. Sending cytokines to attract WBCs. Keratinocyte Stem Cell: Dividing more rapidly to replace cells. Making complement proteins to seek out microbes. Melanocyte: Momentarily detected increased UV radiation in the skin but then the stimulus went away. Langerhans Cell: Identified numerous targets and am eliminating them. Fibroblast: There’s a need for a small amount of new dermal protein fibers. Dermal Dendritic Cell: No unusual activity requiring my services. Merkel Cell: Sensed a sudden increase in pressure in one area of the skin. Lamellated Corpuscle: No signals out of the ordinary.
Using a spare piece of paper or an index card or post it, create a diagram of the skin based on the clues. All 8 cell types and information from the clues should be represented. Show or label your idea of what the skin problem is!
