Melanocyctes contain a pigment called Melanin.
This is what gives people a color to the skin. It
also protects the skin from the sun. It contains
a substance that combines with sunlight to make
Vitamin D.

Contents of the Dermis Layer

• Connective Tissue
• (Proteins Collagen Elastin)
• Penetrated by nerves, veins, arteries, venules,
  arterioles, capillaries, lymph ducts, hair
  follicles, and two types of SWEAT GLANDS
• Apocrine found under arms. Foul odor comes
  from the bacteria eating their milky secretions.
• Eccrine found all over the body and excretes
  salty, acidic water.
• Sweat glands do the job of tiny kidneys, and
  help rid the body of unwanted toxins and body
  waste. The acid helps to protect the skin from
  some harmful bacteria !

Even fingernails, toenails, hair, and the clear
covering of the eye (cornea) are made of skin
cells!

INTERESTING FLESH FACTS

• YOU ARE WHAT YOU EAT A healthy, balanced diet is
  THE KEY to Healthy, Glowing, Radiant, FLESH
  (skin).
• Skin color will change under sustained increases
  in levels of sun exposure due to living near the
  equator.
• Massive doses of UV sunlight change the
  capillaries of the skin, causing them to swell
  (blister) and fill with water. This is called
  SUNBURN.
• Tanning uses UV light to spread the melanocytes
  out evenly across the skin. Freckled people do
  not get a tan, they will get a sunburn instead!
