And What About The Other 5
What Are the Three Layers of Skin? The pores and skin is made up of three layers, each with its own necessary components. 1. The layer on the outside is known as the epidermis (say: eh-pih-DUR-mis). The epidermis is the a part of your pores and skin you can see. 2. The next layer down is the dermis (say: DUR-mis). You cannot see your dermis because it is hidden beneath your epidermis. 3. The third and bottom layer of the pores and skin is called the subcutaneous (say: sub-kyoo-TAY-nee-us) layer. Look down at your hands for a minute. Although you can't see anything occurring, your epidermis is tough at work. At the bottom of the epidermis, new skin cells are forming. When the cells are ready, they start shifting toward the highest of your epidermis. This journey takes about 2 weeks to a month. As newer cells proceed to move up, older cells close to the top die and rise to the surface of your skin.

You can't see your dermis because it's hidden under your epidermis. The dermis accommodates nerve endings, blood vessels, oil glands, and sweat glands. It also comprises collagen and elastin, which are robust and stretchy. The nerve endings in your dermis tell you how things feel when you contact them.
They work together with your mind and nervous system, in order that your mind gets the message about what you are touching. Is it the smooth fur of a cat or the tough surface of your skateboard? Sometimes what you feel is dangerous, so the nerve endings work together with your muscles to keep you from getting harm. For those who touch something scorching, the nerve endings in your dermis reply right away: "Ouch! That's scorching!" The nerves shortly ship this message to the mind or BloodVitals test spinal cord, which then instantly commands the muscles to take your hand away. This all happens in a break up second, without you ever thinking about it. Your dermis is also full of tiny blood vessels.
