Human Eye Model

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

15C

11) Superior Tarsus: lubricates ocular surface

11

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

15B

12) Inferior Tarsus: lubricates ocular surface

12

7) Lacrimal Punctum: drains tears into lacrimal canal

E

#8) Lacrimal Canal: drains tears into lacrimal sac

8 (pink)

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

17

#16) Palpebral Conjunctiva: secretes mucus to lubricate eye

16

#13) Sebaceous Gland: produces oil/sebum

13

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

A

#4) Lateral Rectus: moves eye laterally

4

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

2

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

6

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

16

#3) Medial Rectus: moves eye medially

3

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

5

#7) Sclera: helps maintain eyeball shape

7

#17) Ciliary Muscle: helps change lens shape

17

#9) Lacrimal Sac: drains tears into nasolacrimal duct

9

#8) Cornea: refracts light

8

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

10

Pupil: lets light enter eye

F

#9) Choroid: vascularizes eye

9

#18) Ciliary Processes: secretes aqueous humor

18

#12) Vitreous Humor: helps keep retina in place (against wall of eyeball)

12

#13) Lens: refracts light

13

#17) Ciliary Muscle: helps change lens shape

E

#24) Blind Spot: total insensitivity to light

24

#11) Retina: vision

11

#21 Fovea Centralis: provides sharp central color vision
