Eye

Front 1

2 movable shades that protect the eye from injury, strong light, and dust

Back 1

EYELIDS

Front 2

Elliptical open space between the eyelids, when closed the lid margins approximate completely. When open, the upper lid covers part of the iris.

Back 2

PALPEBRAL FISSURE

Front 3

At the lower lid margin, the border between the cornea and sclera.

Back 3

LIMBUS

Front 4

Corner of the eye, the angle where the lids meet.

Back 4

MEDIAL AND LATERAL CANTHUS

Front 5

At inner canthus, small fleshy mass containing sebaceous gland.

Back 5

CARUNCLE

Front 6

Within upper lid, strips of connective tissue that give its shape.

Back 6

TARSAL PLATES

Front 7

The tarsal plates, contain these which are modified sebaceous glands that secrete an oily lubricating material onto the lids. This stops tears from overflowing and helps to form an airtight seal when the lids are closed.

Back 7

MEIBOMIAN GLANDS

Front 8

Lines the llid and is clear with many small BV. Forms a deep recess and then folds back over the eye.

Back 8

PALPEBRAL CONJUNCTIVA

Front 9

Overlays the eyeball, with the white sclera showing through.

Back 9

BULBAR CONJUNCTIVA

Front 10

Covers and protects the iris and pupil.

Back 10

CORNEA

Front 11

Provides constant irrigantion to keep the conjunctiva and cornea moist and lubricated.

Back 11

LACRIMAL APPARATUS

Front 12

Upper outer corner of the eye and secretes tears.

Back 12

LACRIMAL GLAND

Front 13

Assumption

Back 13

Alexander Hamilton's plan to web creditors to the nation government, by having the national government pay for the states’ debts. In return to southern votes to pass the bill, Hamilton swung northern votes to move the capitol to the Potomac.

Front 14

Each muscle is coordinated or yoked with one in the other eye. This ensures that when the 2 eyes move their axes always remain parallel.

Back 14

CONJUGATE MOVEMENT

Front 15

The eye is a sphere composed of 3 concentric coats name them

SCLERA, CHOROID, RETINA

Front 16

Outer fibrous coat

Back 16

SCLERA

Front 17

Middle vascular coat

Back 17

CHOROID

Front 18

Inner Nervous coat

Back 18

RETINA

Front 19

Tough, protective, white covering. Its continuous anteriorly with the smooth, transparent cornea, which covers the iris and pupil.

Back 19

SCLERA

Front 20

Very sensitive to touch, contact a wisp of cotton stimulates a blink with both eyes called

Back 20

CORNEA
CORNEAL REFLEX

Front 21

In middle layer, has dark pigmentation to prevent light from reflecting internally and is heavily vascularized to deliver blood to the retina. Anteriorly it is continuous with ciliary body(control thickness of the lens) and iris.

Back 21

CHOROID

Front 22

Round and regular, size is determined by a balance of para. and symp. chains of ANS. Para. stimulation through CN III caues constriciton. Symp stimulation dilates the pupil and elevates the eyelid. It also reacts to the amount of ambient light

Back 22

PUPIL

Front 23

Biconvex disc located posterior to the pupil. Serves as a refracting medium, keeping viewed objects in continual focus on the retina. Thickness is controlled by ciliary body, it bulges for focusing on near objects and flattens for far objects.

Back 23

LENS

Front 24

In posterior chamber contains this which is clear, watery, that is produced by the ciliary body. It serves to deliver nutrients to the surrounding tissues and to drain metabolic wastes.

Back 24

AQUEOUS HUMOR

Front 25

Visual receptive layer in which light waves are changed into nerve impulses. Surrounds the soft gelatinous vitreous humor.

Back 25

RETINA

Front 26

Area in which fibers from the retina converage to form the optic disc.

Back 26

OPTIC DISK

Front 27

Include a paired artery and vein extending to each quadrant.

Back 27

RETINAL VESSELS

Front 28

Area of the sharpest and keenest vision.

Back 28

FOVEA CENTRALIS

Front 29

Adaptation of the eye for near vision. Increase the curvature of the lends through movement of ciliary muscles.

Back 29

ACCOMMODATION

Front 30

Glasslike quality decreases the lens ability to change shape to accommodate for near vision

Back 30

PRESBYOPIA

Front 31

Perception of 2 images of a single object

Back 31

DIPLOPIA

Front 32

Protruding eyes

Back 32

EXOPHTHALAMOS

Front 33

Suken eyes

Back 33

ENOPHTHALMOS

Front 34

Pupils of 2 different sizes
