Anatomic Terms

Question 1

anterior chamber

Answer 1

fluid filled space between the cornea and iris

Question 2

aqueous humor

Answer 2

watery liquid secreted by the ciliary processes that fills the anterior and posterior chambers of the eye and provides nourishment for the cornea, lens and iris
humor = fluid

Question 4

choroid

Answer 4

vascular layer beneath the sclera that provides nourishment to the outer portion of the retina

Question 5

ciliary body

Answer 5

ring of tissue behind the peripheral iris the is composed of ciliary muscle and ciliary processes

Question 6

ciliary muscle

Answer 6

smooth muscle portion of the ciliary body which contracts to assist in near vision

Question 7

ciliary processes

Answer 7

epithelial tissue folds on the inner surface of the ciliary body that secrete aqueous humor

Question 8

conjunctiva

Answer 8

mucous membrane that lines the eyelids and outer surface of the eyeball

Question 9

cornea

Answer 9

transparent anterior part of the eyeball covering the iris, pupil and anterior chamber that functions to refract light to focus a visual image

Question 10

palpebra

Answer 10

eyelid

Question 11

fovea centralis

Answer 11

pinpoint depression in the center of the macula lutea that is the site of sharpest vision

Question 12

fundus

Answer 12

interior surface of the eyeball including the retina opti disc macula lutea and posterior pole

Question 13

zeis glands

Answer 13

oil glands opening into the follicles of the eyelashes

Question 14

tarsal glands

meibomian glands

Answer 14

oil glands located along the rim of the eyelids

Question 15

iris

Answer 15

colored part f the eye located behind the area that contracts and dilates to regulate light passing through the pupil

Question 16

lacrimal gland

Answer 16

gland located in the upper outer region above the eyeball that secretes tears

Question 17

lacrimal ducts

Answer 17

tubes that carry tears to the lacrimal sac

Question 18

lacrimal sac

Answer 18

structure that collects tears before emptying into the nasolacrimal duct

Question 19

lens

Answer 19

transparent structure behind the pupil that bends and focuses light rays on the retina

Question 20

lens capsule

Answer 20

capsule that encloses the lens

Question 21

macula lutea

Answer 21

central region of the retina responsible for central vision

Question 22

nasolacrimal duct

Answer 22

passageway for tears from the lacrimal sac into the nose

Question 23

optic disc

Answer 23

exit site of retinal nerve fibers as well as entrance point for retinal arteries and exit point for retinal veins

Question 24

optic nerve

Answer 24

nerve responsible for carrying impulses for the sense of sight from the retina to the brain

Question 25

posterior chamber

Answer 25

space between the back of the iris and the front of the vitreous chamber; filled with aqueous humor

Question 26

pupil

Answer 26

black circular opening in the center of the iris through which light passes as it enters the eye

Question 27

retina

Answer 27

innermost layer that perceives and transmits light to the optic nerve

Question 28

cones

Answer 28

cone shaped cells within the retina that are color sensitive and respond to bright light

Question 29

rods

Answer 29

rod shaped cells within the retina that respond to dim light

Question 30

sclera

Answer 30

tough fibrous white outer coat extending from the cornea to the optic nerve

Question 31

trabecular meshwork

Answer 31

mesh like structure in the anterior chamber that filters the aqueous humor as It flows into the scleral venous sinus

Question 32

vitreous

Answer 32

jelly like mass filling the inner chamber between the lens and retina that gives bulk to the eye
