  1. Eyebrows - Catch sweat or debris coming off the forehead into the eye.
  2. Eyelashes - Hairs growing at the edge of the eyelid which are very sensitive, tactile receptors.
  3. Eyelids - 4 layers of tissue (they're actually the thinnest tissue in the body).
  4. Lacrimal Glands - Release tears, water, lysoenzymes, salts, oxygen, and nutrients.
  5. Conjunctiva - Inner layer eyelid lying on cornea.
  6. Tarsal Glands - Located next to the eyelashes, secrete substances to keep the eyelids from sticking together.
