The micrographs show various areas of the skin. What are the characteristics that distinguish “thick skin” from “skin with hair” (or “thin skin”).
1. Resistance to trauma and infection - becasue the epidermal cells are packed with keratin, few things can penetrate skin
2. Other barrier functions - Prevents body from losing or gaining excess water and barrier to UV rays and chemicals
3. Vitamin D synthesis - first step of synthesis
4. Sensation - most extensive sense organ with variety of nerve endings
5. Thermoregulation - richly supplied with nerve endings which monitor the body's surface temp and can release or retain heat by way of vasoconstiction(dilation) and sweating or shivering
