(via Science Photo Library)Cross section of a human fingertip (distal phalanx). A thick pad of subcutaneous fat (yellow) protects the bone, vessels, and nerves. The root of the finger nail is tucked into the nail groove, a folded pocket of skin which makes up the cuticle.
Been having fun learning how to paint my nails lately, and to take care of them. So naturally, I got all fascinated about what they look like inside. XD And in the process, became reminded of just HOW HAPPY cross sections make me!
