EYELID, loose fold of skin

covers anterior portion of eyelids

manually protects the eye

Bulber- anterior scalera

Palperbral- inner surface of palperbael eyelid

6

Lacrimal Apparatus:

lacrimation-secretion of tears
Lacrimal fluid-tears
lubricates the CORNEA & CONJUCTIVAE

Lysozyme- anti-bacterial enzyme in tears

7

Larimal Glands:

produce lacrimal fluid/tears

location: lateral/ superior palpebrae/eyelids

Punctum:

tiny openings in medial compus

function:drains tears into canals
