The differences between thick and thin skin
This is a picture of an H&E stained section of the epidermis of thick skin.
Can you identify the five major layers of the epidermis?
Dermis: Thick skin has a thinner dermis than thin skin, and does not contain hairs, sebaceous glands, or apocrine sweat glands.
Thick skin is only found in areas where there is a lot of abrasion - fingertips, palms and the soles of your feet.

There are only four layers in the epidermis of thin skin. The stratum lucidum layer is absent. What do you notice about thicknesses of the different layers?
How pronounced are the dermal papillae compared to thick skin?
Dermis: Thin skin actually has a thicker dermis than thick skin, which makes thin skin easier to suture, if it gets damaged. Thin skin also has fewer eccrine/merocrine sweat glands.
This is a picture of a diseased skin - a very common condition - can you tell what it is?
