Evolution of Skin Video (Will be Viewed in Class)
- The evolution of skin:
- In your notebook, jot down notes as you watch.
- Each segment describe features that evolved over time that became common and important structures for almost ALL organisms, including us.
- List the feature and describe its current physiology in human skin.
Day Starter Starter for ____
- Record at least 2 features about skin that you didn't previously know!
- All human structures, including the skin, have been perfected over hundreds of millions of years. The journey to where we are now, had some interesting evolutionary background. Your assignment will be to take that long journey and summarize it. You can do this in really any way you'd like. The most basic version would be a WELL WRITTEN one page summary from your video notes. Some other ideas could be:
- A general timeline showing in order WHEN structures arose, along with an explanation of their physiology.
- A series of drawings or diagrams to depict these important structures.
- A PowerPoint that highlights the anatomical features as well as their current physiology.
This is a 10 point assignment - but if you go above and beyond the minimum of a one page summary, extra credit (up to 4 points) will be rewarded! Creativity highly encouraged. Click the link below to submit your assignment.
Visible Body intro to Integumentary Assignment:
Overall Instructions:
- Please carefully read the instructions below and complete the tasks in order while navigating visible body.
- You will need your 4.1 notes (we will ENHANCE them), and your labeling skin worksheet.
- You will also be completing items in the GoogleDoc below as you navigate.
- Please read all sections carefully! There should be no rush in getting this completed.
Complete the following tasks...
1) Click on chapter 6 - "the integumentary system"
2) Starting at 6.1 (Skin layers), do an interactive tour, while looking at notes. While reading add anything new or helpful to your notes and/or skin diagram. Answer questions 1 & 2 (GoogleForm).
3) Continue to 6.2 - Epidermis. Click on each layer in the compare relative THICKNESS of each. Record a ranking of this in your notes. (Answer qs 3-4)
4) Continue to 6.3 - Epidermis Histology. Read carefully the information on slide 1. Add any unique info to your notes. As you click on slides 2-4, answer questions 5-7
5) Continue to 6.4 - Skin Cells. PLEASE ADD THE IMAGES OF THE CELLS TO YOUR NOTES. Drawings need to depict uniqueness of each cell. Answer the two very serious questions in the form (questions 8-9).
6) Continue to 6.5 - Epidermal Cells. This information was mostly covered so simply review and move to 6.6.
7) 6.6 - Dermal Layers. Review the layers of the dermis. Add any new information to your notes. Answer questions 10-11.
8) 6.7 - Dermal Histology. Compare the reticular layer and the papillary layer: Answer question 12.
9) 6.8 - Thick vs. Thin Skin.
