Great video! I may have missed it but I think it would be good to point out that the Stratum lucidum only appears in the thick skin (palms of hands and bottoms of feet) and not on the thin skin (everywhere else). It is to make our hands and feet tougher by providing an additional layer of protection. Imagine holding a really warm cup of coffee in your hands... it's kind of relaxing. But touch that same warm cup of coffee to your neck and we've got a whole different situation.

A nice way to remember the layers:

Come
Lets
Get
Sun
Burn

I really like how you seperated the layers and illustrated terms within the layer.

You guys are amazing. I love everything about this channel: I like the way information is presented, I like the wording and the analogies, - everything. Just Awesome!

The stratum basale is just a single layer of keratinocytes.

You are my favourite teacher on Khan Academy! Always so concise and easy to follow! I just spent 2 hours reviewing the integumentary system earlier for my test today and damn, it's amazing how great you've visually shown all that info into one concise video :) Looking forward to more vids from you!

Excellent "crash course" for understanding the Epidermis. I think the Granulosum layer is the most Intricate of all the layers.

Stratum corneum is absent in very low birth weight infants

You really need to explain the function of skin to all those people who constantly cut themselves for what seems like kicks if you ask me.
I'm a paramedic. Apparently my opinion of the matter, my words about microbes being kept at bay by the barrier of skin that stops infections doesn't rate with them because the same people do this over and over and over. I must take these people to the hospital once a month. I'm really surprised they haven't actually gotten a terrible infection, but I really wouldn't play around with bacteria the way they do.
I took Microbiology in Paramedic School. It was a most eye-opening experience.

So, do reptiles have a lucidum layer? or do they only have 4 layers? or does this not pertain to reptiles in the way I think it does... haha. I also thought this was very informative and a lot of fun! I did remember a song because of your intro, "Your epidermis is showing." I grew up very religious (am not anymore) but if you have ever listened to dc talk-colored people, it says all that in the beginning. I had not thought of that song in over 15 years. Anywho great slide, and now I will remember what is in the layers, Loved the zombie and coroners talk!
