2.Knotted umbilical cords are usually a death sentence for babies, so examples where the baby was totally fine are super cool. (Also, I had never seen an umbilical cord before, so that was fascinating in itself.)

3.In case you don't know, the placenta is an organ that grows in the uterus during pregnancy and helps to keep the baby alive and healthy. This is what one looks like.

5.I doubt you've ever heard of the disorder Amelogenesis Imperfecta, but here's what it looks like. Basically, it affects and weakens tooth and enamel development and can manifest like this.

7.I doubt you've ever heard of Trichomegaly either — basically, it means you've got super long lashes. That might sound like a dream, except...well, it isn't necessarily so great.

12.Though kidney stones CAN get really big (something like this would require surgical removal; don't worry, no one's peeing this out).

13.This isn't technically a photo of the human body, but I still think it's awesome. Did you know there's technology now to show where veins are beneath the skin?

14.Modern medicine is amazing, y'all. Just look at the things we can implant in bodies — and then take out without damage.

15.TIL about the nail disorder Onychogryphosis, or "ram's horn nail." This is what it can look like.

16.Similarly, this is what Epidermodysplasia Verruciformis looks like on hands — basically, it's warty lesions that form everywhere.

17.Look, I come into these posts wanting to learn and educate, but I have to admit, I have no idea what's going on here besides some kind of hypermobility or double-jointedness. Still...cool, right?

18.In case you want nightmares, it turns out it's possible to GROW A WISDOM TOOTH NEAR YOUR EYE SOCKET.

23.Did you know it's possible to regrow an ear??? That's oversimplifying it, but it's essentially what doctors did for this patient. After she lost her ear in a car accident, they used rib cartilage to create an ear, then put it in her forearm, where it was able to form new blood vessels. Awesome, right?

24.This is what it looks like to have Neurofibromatosis, where tumors grow on your nerves.

25.However, it can get a lot more serious than the above image. For example, this man had over 60 pounds of tumors on his face as a result of Neurofibromatosis. He's since had them removed.

26.Ehlers-Danlos Syndrome can manifest in a few different ways, but one of the more common ones is that your skin becomes stretchy and fragile. You may be able to do this, for example.

27.Did you know that if you have surgery on your fingers that affects your nail bed, they'll actually put a fake nail there to keep the nail fold open while your real nail grows back?

28.Did you know if you're dehydrated or lacking vitamin C (especially to the point of having scurvy), old scars can reappear or become more noticeable than they ever were before?

29.Our bodies are incredible. They'll work foreign bodies out of our skin, sometimes over the course of years.

31.Have you ever heard of Hydrocephalus? It's where spinal fluid builds up in your brain, causing it to balloon in size. Treatment involves brain surgery to redirect the fluid.

35.Surgery can disrupt or damage nerves, which can have strange effects...like this person who had a nerve temporarily paralyzed as a part of surgery and then had a spot that didn't grow hair for a while.

38.You may have heard of Milia if you watch dermatology extraction videos (no one else? just me?), but basically, it's a little ball of keratin that forms under your skin, usually on your face.

41.And finally, here are some more gallstones — this type is called cholesterol stones (the cholesterol explains the color). Sorry. Don't worry — you can get your gallbladder out, which this person did.
