BIOS251 OL, Week 5 Lab Name: 3. Identify the condition that would occur due to increase in body temperature. Part C: Skin Wound Healing- Anatomy TV Instructions: For this part of the lab you will use Anatomy TV to watch an animation on skin wound healing. Please read the instructions before you begin. 1. Use the link below to log into Anatomy TV via Chamberlain Library. https://library.chamberlain.edu/az.php?q= . 2. Select Anatomy TV under popular databases to access the site. 3. Select the ‘Integumentary System’ tile: 4. Select topics and click on Skin Wound Healing . 5. Watch the animation to answer the questions below: 1. Compare and contrast the epidermal and dermal wound healing.
BIOS251 OL, Week 5 Lab Name: 2. Describe the first step in wound healing. What its significance? 3. Why is inflammation an important step in wound healing? 4. What results in fibrosis during deep wound healing? Part D: Case Studies : Read the case study. In your own words and in complete sentences answer the questions. Case Study 1 While preparing dinner Jane knocked a pan of boiling water onto herself. She suffered partial thickness burns to the anterior region of her legs. 1. What is partial thickness burns? 2. Jane loose sensation of the affected area? Why?
BIOS251 OL, Week 5 Lab Name: 3. Using the Rule of Nines calculate the total body surface area percentage that is burned? Case Study 2 Tom, a 14-year-old teenager, fell into the partially frozen pond during his walk with his friends. His friends rescued him and took him back to the car. On the walk back, Tom, started to show signs of hypothermia. 1. What is hypothermia? 2. Which skin receptors detect a decrease in temperature? 3. Which control center monitors the signaling from these skin receptors? 4. What happens to the blood vessels in the skin during hypothermia? What is the purpose of this response? 5. What will happen to the hairs in Tom’s skin? What is the purpose of this response?
