The study of form and markings of the body's surface, especially as they relate to internal structures.
In other words, even though your body is mostly covered with skin, you can still locate areas of internal anatomy by noticing creases, bulges and other characteristics in the skin. You can picture exactly where a certain bone or muscle lines up, and follow it as the body moves. Where the bone connects to the skin you often find creases. Where the skin bulges you often have muscle. When the skin looks as if a cord is lying underneath, you're looking at a tendon. Where you find bumps as in the face, you're observing bone or cartilage protruding. In a way, by learning surface anatomy, you can virtually look through someone's skin and accurately imagine what's happening underneath.
In addition surface anatomy includes those structures that are outwardly exposed or openings to the outside of the body, including the eyes, ears, nose, mouth, nipples, belly button or umbillicus, anus, and external genitals or external sexual organs.
Use a sun block with a sun protection factor (SPF) of at least 15 when exposing your skin to the sun. Any outdoor activity for which you wear shorts and t-shirts or less puts you at risk for ultraviolet radiation. Ultraviolet radiation causes wrinkles, skin cancer and accelerates the aging process. Skin cancer is the most common form of cancer known to man. Girls, if you want to have beautiful skin for a long time, use a skin moisturizer that doubles as a sunscreen. They're not as thick as regular sunscreen, don't clog pores and come unscented. Men before shaving soften your skin with soap and WARM water. Follow the growth of the beard. Don't shave against the grain. This way you can avoid uncomfortable ingrown hairs, which resemble pimples.
Do not suntan or go to tanning booths or you will look like a leathery John Rivers by the time you're 22.
Be aware of your skin's normal features. If you notice a mole that changes texture, or grows larger, darker or more irregular, have your doctor check it out for skin cancer. Do the same for sores that don't heal or persistently reoccur.
Splinter? If the splinter has not drawn blood, there is no need to visit the emergency room. Grab some Scotch tape and apply it to the splinter and surrounding skin. Press it firmly against the skin to insure it is adhered to the splinter. Slowly pull off the tape. This theoretically should pull out the splinter. If it doesn't, maybe duck tape will. If that doesn't, resort to good old fashion tweezers. When using tweezers, be careful to pull the splinter out in the opposite direction as it went in, in order to avoid breaking off the end. If these techniques fail miserably, don't worry. Your skin is constantly generating new skin cells. Your body sheds 500 million dead skin cells a day. In less than a week, the movement of new skin cells toward the surface will push the splinter to the surface as well.
