Hello and welcome back friends from the US, India, Turkey, Canada, France, the UK, Ireland, Argentina, and Ukraine 😉
Sometimes, you say crazy things, don’t you? It’s out of the too many questions you have in your mind. Lots and lots of questions again and again.
Hey, make a guess, but if you insist, it’s on our list! Whether the published list or the coming list, you’ll find your answers n its folds.
You see, your skin can be soft or wrinkly, it can be light skin or dark skin, but perhaps you never thought about what’s under y our skin.
What’s on the top is just the beginning of the skin.
The epidermis is like a skin cell factory. New cells are being born at the bottom all the time and slowly making their way up to the top. It takes the cells about four weeks to get all the way up and by the time they finally make it to the surface, they’re dead so you’re shedding dead skin cells all the time.
The epidermis also contains melanin and it’s what makes your skin darker or lighter. The more melanin you have the darker your skin will be. Skin comes in many beautiful colors. Melanin also helps protect you from the Sun. It sure does but even melanin can’t do it all and that’s why we wear sunscreen to keep it from getting burned.
How about the dermis? It is where your blood vessels and your nerves end. Nerve endings send messages to the brain but what is the skin trying to tell the brain?
Guessing that terrible pun means that this has to do with the sense of touch.
Your skin touches rough tree bark, cold snowball, a nice cup of hot chocolate, nerve endings read all of these sensations and tell the brain and nervous system about them. Then the brain and nervous system decide if the body needs to respond. For example, if you touch something too hot your nervous system tells your hand to move away from it exactly.
Wow! May be you never knew that your skin is so smart!
Not only it feels hot or cold but your skin also detects other touches such as your fabulous sweat and oil glands, which keep you wonderfully sticky and sweaty. Good oil glands or sebaceous glands make a sticky substance called “sebum” that moves where it creates an oily layer that protects and moistened your skin sebum.
It also makes your skin a little waterproof but the sweat glands start here in the dermis where they make sweat that travels up to the epidermis where the sweat comes out of holes cold pores.
The last stop on the skin layer is expressed via the hypodermis: fat. Why do you need fat? The body needs some fat to cushion and help protect your bones and organs. This layer of fat also helps keep you nice and toasty warm.
What else is down there?
The hair starts all the way down here and the hair does it at a more reasonable speed. Near the base of the hair there are little muscles called a rector or PI line but tighten when you’re cold and pull the hair so it stands up straight it’s called the PI loner reflex that’s what makes all those little bumps pop up on your skin.
In other words, your goose bumps. Your blood vessels in the dermis when you’re cold they make themselves really small to keep all your nice warm blood far away from the cold air outside your skin.
When you’re hot those blood vessels bring all the blood closer to the surface of the skin so you can cool down. When you run a lot my your face gets red. It is precisely why and the sweat glands help here too; they produce a lot of sweat on the surface of the skin which evaporates and disappears cooling you down in the process.
