1

The complex movable cover of the outer portion of the eyeball, consisting of an upper/lower component of skin, tarsus, delicate muscles, eyelashes, glands, and conjunctiva is

The eyelid

2

The almond-shaped opening between the upper and lower lids is the

Palpebral Fissure

3

The point where the lids meet on the nasal (inner) side of the palpebral fissure is the

Medial Canthus

4

The temporal (outer) junction of the lids is the

Lateral Canthus

5

This structure, also known as cilia, help protect the eye by sweeping away airborne dust particles and other foreign matter when the lids blink. These are the

Eyelashes

6

When an eyelash grows in the wrong direction and rubs the surface of the eye, irritating the cornea, it is called __________

Trichiasis

7

If a lash follicle becomes inflamed and produces a reddened, sore lump near the outer edge of the lid, it is called _________

Stye/External hordeolum

8

located on the posterior margin of the lid, there is a row of tiny holes, the openings of oil secreting glands hidden in the tissue of the lids called ________

Meibomian glands

9

Should a Meibomian gland become inflamed and infected, it may produce a swelling on the inner lid called _____

Internal hordeolum

10

Chronic inflammation resulting from an obstructed Meibomian gland may form a

Chalazion

11

A very common inflammation of the eyelid margin resulting in redness and crusting is called

Blepharitis

12

A dense plate-like framework, which gives eyelids their firmness and shape is called

The tarsus/tarsal plate

13

a circular muscle that closes the eye when is contracts is the

Orbicularis Oculi

14

When this muscle contracts, it raises the upper lid, this is the

Levator Palpebrae

15

When the upper lid droops and cannot lift fully it is a condition called

Ptosis

16

Malformations of the eyelid or damage to them causing the lower lid margin to fall or pull away from the eye is a condition called

Ectropion

17

When the upper or lower lid margins are turned upward this results in a condition called

Entropion

18

A thin, translucent mucous membrane that lines the inner surface of the lids and the outer front surface of the eyeball, except for the cornea is the

Conjunctiva

19

The portion of the conjunctiva that lines the eyelids is called

The Palpebral Conjunctiva

20

The portion of the conjunctiva that covers the outer eyeball is called

The bulbar conjunctiva

21

The area where the palpebral and bulbar portions of the conjunctiva meet beneath the upper and lower lids forming a loose pocket of tissue is

The Fornix/Cul-de-sac
