Anatomy of the Eye

Flashcards covering the anatomical structures of the eye, based on lecture notes.

Transverse Plane

A plane that divides the body into superior and inferior parts.

Ciliary Body

Part of the eye containing the ciliary muscle and ciliary process.

Ciliary Muscle

Controls the shape of the lens for focusing.

Ciliary Process

Produces aqueous humor.

Medial Rectus Muscle

Muscle that moves the eye medially.

Vitreous Chamber

Large cavity filled with a gel-like substance.

Vitreous Body

Gel-like substance filling the vitreous chamber.

Blood Vessels (Eye)

Carries blood to and from the eye.

Scleral Venous Sinus

Drains aqueous humor from the anterior chamber.

Anterior Cavity

Area between the cornea and the lens, filled with aqueous humor.

Cornea

Clear outer layer of the eye that helps focus light.

Pupil

Opening in the iris that allows light to enter the eye.

Iris

Colored part of the eye that controls the size of the pupil.

Zonular Fibers

Fibers that suspend the lens.

Lens

Focuses light onto the retina.

Conjunctiva

Membrane that covers the outer surface of the eye and lines the eyelids.

Optic (II) Nerve

Transmits visual information from the retina to the brain.

Optic Disc (Blind Spot)

Area on the retina where the optic nerve exits; lacks photoreceptors.

Fovea Centralis

Area of the retina with high concentration of cones; provides sharp central vision.

Retina

Innermost layer of the eye containing photoreceptors.

Choroid

Middle layer of the eye containing blood vessels.

Sclera

Tough, outer layer of the eye that provides protection.

Lateral Rectus Muscle

Muscle that moves the eye laterally.

Macula Lutea

Area of the retina surrounding the fovea; important for central vision.

Iris

Located under the cornea.

Sclera

Located under the conjunctiva.

Eyebrow

Located above the eye.

Upper Eyelashes

Located on the upper eyelid.

Eyelid

Protective fold of skin

Pupil

Located under the cornea.

Conjunctiva

Covers the sclera.

Lower Eyelid

Protective fold of skin on bottom of eye.
