Human Eye Model

#15c) Lateral Canthus: area where the inferior and superior eyelids meet laterally

A

11) Superior Tarsus: lubricates ocular surface

B

15b) Medial Canthus: area where the inferior and superior eyelids meet medially

C

12) Inferior Tarsus: lubricates ocular surface

D

7) Lacrimal Punctum: drains tears into lacrimal canal

E

#8) Lacrimal Canal: drains tears into lacrimal sac

F

1) Lacrimal Gland: produces tears

A

5) Excretory Ducts of Lacrimal Gland: drains the lacrimal gland of tears

B

#17) Bulbar Conjunctiva: secretes mucus to lubricate eye

A

#16) Palpebral Conjunctiva: secretes mucus to lubricate eye

B

#13) Sebaceous Gland: produces oil/sebum

C

#1) Superior Rectus: elevates eye & turns it medially

A

#4) Lateral Rectus: moves eye laterally

B

#2) Inferior Rectus: depresses eye and turns it medially

C

#6) Inferior Oblique: elevates eye and turns it laterally

D

#16) Optic Nerve: CN#2, transmits visual signals from optic disc

E

#3) Medial Rectus: moves eye medially

F

#5) Superior Oblique: depresses eye and turns it laterally

G

#7) Sclera: helps maintain eyeball shape

A

#17) Ciliary Muscle: helps change lens shape

B

#9) Lacrimal Sac: drains tears into nasolacrimal duct

C

#8) Cornea: refracts light

D

#10) Iris: controls how much light enters the eye

E

Pupil: lets light enter eye

F

#9) Choroid: vascularizes eye

A

#18) Ciliary Processes: secretes aqueous humor

B
