JCAHPO COA FINAL PAPER COMPLETE
SOLUTIONS 2026 GRADED A+
⫸ Sclera. Answer: white opaque fibrous shell, main purpose is to
protect eye
⫸ Cornea. 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. Answer: The largest oil-secreting glands, which
are embedded in the posterior connective tissue substance of the lids
⫸ Corneal Epithelium. 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. Answer: Part of the cornea that regenerates
rapidly and heals without leaving a scar.
⫸ Bowman's membrane. Answer: Consists of randomly oriented
collagen fibrils of greater periodicity then the underlaying stroma.
⫸ Bowman's membrane. Answer: Acellular layer of cornea that has no
regenerative capabilities. Function is unclear.
, ⫸ Stroma. Answer: Layer just under Bowman's membrane. Accounts
for 90% of corneal thickness and is composed of 78% water.
⫸ Descemet's membrane. Answer: Layer of the cornea that is composed
of type III collagen, forms the basement membrane of epithelial cells.
⫸ Endothelium. Answer: 4-6um thick layer of the cornea made of
500,000 cells that maintains corneal deturgescence. No regenerative
abilities.
⫸ Limbus. Answer: The gray, semitransparent area which demarcates
the junction of the cornea and sclera.
⫸ Cornea is completely nourished by. Answer: 3 sources: A plexus of
fine capillaries at the limbus, the tear film, and the aqueous humor.
⫸ Vitreous. Answer: jelly like structure, thick and viscous, that
occupies the vitreous chamber in the posterior concavity of the globe.
⫸ Lens. Answer: A transparent biconvex structure situated between the
iris and the vitreous.
⫸ Iris. Answer: The most anterior structure of the uveal tract.
