About Skin Layers and Organ Anatomy: Follow a skin cell’s journey! Virtual Lab Simulation
What secrets are hidden under your body’s biggest organ? In this simulation, you will learn about the two main parts of your skin – the epidermis and the dermis. Discovering their secrets will help you understand why we need this adaptive and incredibly flexible protective coat, together with its many structural components like hair, nails, and sweat glands.
Layers of the epidermis
Jump into an animation and discover the variety of cells that make up five layers of the epidermis. Observe newborn keratinocytes, a type of skin cell, on their journey to the upper skin layer, where they are eventually shed off. Find characteristic features of each layer that facilitate skin functions and confirm that melanin has a more important role than just giving us our dashing skin color.
Keratinocyte transformation in skin layers
Follow the primary skin cell, keratinocyte, on its journey through layers of the epidermis – from a newborn keratinocyte in stratum basale up to old and keratin-rich corneocyte in stratum corneum! Observe how the cell transforms and determine what additional structures or compounds it will require on this dangerous quest to the upper-most layer of skin. Will it reach its destination or fail spectacularly in the depths of stratum granulosum?
Structural components of the dermis
After familiarizing yourself with the epidermis, you will discover what specialized structures are embedded in the dermis. Does sweating play a significant role in keeping our body healthy? Try matching the structural components of the dermis (hair, nerves, capillaries, oil, and sweat glands) with their functions. Maybe walking around with greasy hair is not that bad for your skin?
