Understanding skin anatomy goes beyond just what we see on the surface. This chapter introduces the basics of skin structure by looking at it in three different ways: histology, ultrasound, and MRI with surface coil. Histology is like taking a close-up look under a microscope, where we can see the different layers of the skin and how they are made up of tiny cells. Ultrasound allows us to see inside the skin, showing us the different layers and any changes or issues that might be happening. MRI with surface coil, on the other hand, gives us a very detailed picture of the skin, showing even deeper layers and structures. By combining these three methods, we get a full understanding of how the skin is built and how it works. This chapter is useful for anyone studying or working with skin, as it explains the important details of skin anatomy in a clear and simple way.
