Certified Paraoptometric (Basic Anatomy) - Questions
With A+ Solutions
Chamber, anterior Correct Answer - the area inside the eye, behind the
cornea and in front of the iris
Aqueous humor Correct Answer - a clear, watery fluid produced by the
ciliary body
Aqueous humor, purpose Correct Answer - provides nutrients for the lens
and posterior cornea, carries away waste products, and maintains intraocular
pressure
Aqueous humor, location Correct Answer - fills the front part of the
posterior chamber and the entire anterior chamber
Choroid Correct Answer - blood vessels that nourish the retina
Choroid, location Correct Answer - sandwiched between the sclera and the
retina
Ciliary muscle Correct Answer - interior muscle that alters the shape of the
crystalline lens
Ciliary muscle, process involvement Correct Answer - has direct control
over the focusing ability of the eye, called "accommodation"
Conjunctiva Correct Answer - a clear, cellophane-like tissue that covers the
sclera and the inside surface of the eyelids
Conjunctiva, palpebral Correct Answer - a clear, cellophane-like tissue that
covers the inside surface of the eyelids
Conjunctiva, bulbar Correct Answer - a clear, cellophane-like tissue that
covers the sclera
Cornea Correct Answer - a clear, transparent tissue that provides most of
the eye's ability to focus light
, Cornea, location Correct Answer - on the anterior portion of the eye, over
the iris
Cornea, purpose Correct Answer - the most refractive part of the eye, it
provides most of the eye's ability to focus light
Cornea, layers Correct Answer - five: epithelium, Bowman's layer, stroma,
Descemet's membrane, endothelium
Epithelium Correct Answer - outermost layer of cells in the cornea
Bowman's layer Correct Answer - the second layer of the cornea
Stroma Correct Answer - the middle layer of the cornea
Descemet's membrane Correct Answer - the second-innermost layer of the
cornea
Endothelium Correct Answer - the innermost layer of the cornea
Crystalline lens Correct Answer - the second most refractive medium in
the eye, provides additional focusing power
Crystalline lens, purpose Correct Answer - allows adjustment of the eye to
focus from distant objects to near objects
Oblique Correct Answer - a muscle neither parallel nor perpendicular to
the long axis of a body or limb
Rectus Correct Answer - straight muscles, as of the abdomen, eye, thigh,
etc.
Extraocular muscles, number Correct Answer - six: medial rectus, inferior
rectus, lateral rectus, superior rectus, superior oblique and inferior oblique
Adduction Correct Answer - movement of a body part toward the midline
