levator palpebrae superioris - CORRECT ANSWER-Muscle that elevates the lid
Sclera - CORRECT ANSWER-white opaque fibrous shell, main purpose is to protect
eye
Cornea - CORRECT ANSWER-A transparent convex covering which protects the eye
and helps focus light rays onto the retina and the back of the eye
meibomian glands - CORRECT ANSWER-The largest oil-secreting glands, which are
embedded in the posterior connective tissue substance of the lids
Corneal Epithelium - CORRECT ANSWER-Part of the cornea that is usually injured by
superficial abrasions or small foreign bodies. Is 5-7 cells thick and is composed of
nonkeratinized stratified squamous cells.
Corneal Epithelium - CORRECT ANSWER-Part of the cornea that regenerates rapidly
and heals without leaving a scar.
Bowman's membrane - CORRECT ANSWER-Consists of randomly oriented collagen
fibrils of greater periodicity then the underlaying stroma.
Bowman's membrane - CORRECT ANSWER-Acellular layer of cornea that has no
regenerative capabilities. Function is unclear.
Stroma - CORRECT ANSWER-Layer just under Bowman's membrane. Accounts for
90% of corneal thickness and is composed of 78% water.
Descemet's membrane - CORRECT ANSWER-Layer of the cornea that is composed of
type III collagen, forms the basement membrane of epithelial cells.
Endothelium - CORRECT ANSWER-4-6um thick layer of the cornea made of 500,000
cells that maintains corneal deturgescence. No regenerative abilities.
