  1. 'tear duct.' almond shaped gland, situated in upper outer portion of each orbit. secretes aqueous layer of tears
    lacrimal gland
  2. lines the inside of the eyelids, covers the sclera (white part of the eye). secretes a small amount of tears.  forms a protective barrier and supports the immune system of the eye.
  3. sebaceous glands at rim of the eyelids.  secretes meibum, a lipid component of tears that prevents tears' leaving the eye
    tarsal glands
  4. globular nodules in inner corner of each eye.  sebaceous and sudoriferous glands covered in skin.
    lacrimal caruncle
  5. upper dilated end of the nasolacrimal duct. connects the lacrimal canaliculi, which drain tears from the eye's surface, and the nasolacrimal duct, which conveys this fluid into the nasal cavity.
    lacrimal sac
  6. carries tears from the lacrimal sac into the nasal cavity.
    nasolacrimal duct
  7. clear eye debris, reduce friction with the eyelids, produce antibiotic lysozymes, provide oxygen and nutrients to the cornea
  8. location where ganglion cell axons exit the eye to form the optic nerve.  without light responsive molecules, creates the 'physiological blind spot.'
    optic disc
  9. transmits visual information from the retina to the brain.
    optic nerve
  10. surrounds most of the eye between the retina and the sclera.  made of vascularized connective tissue
  11. the opaque, fibrous, protective, outer layer of the eye containing collagen and elastic fiber.
  12. a light-sensitive layer of tissue, lining the inner surface of the eye.
  13. occupies the posterior 4/5 of the eyeball. This chamber of consists of the space between the lens and the retina, and is filled with a transparent gel called the vitreous humor.
    vitreous chamber
  14. the transparent front part of the eye that covers the iris, pupil, and anterior chamber.  continuous with the sclera.  has no vasculature but has unmyelinated free nerve endings sensitive to touch.
  15. eye layer composed of the sclera and cornea.
    fibrous tunic
