Chapter 16 Special Senses Medical Terminology Chapter 16 Special Senses

Structures of Eyes Sclera conjunctive choroid retina cornea lens anterior cavity aqueous humor

Structures of Eyes Iris pupil vitreous chamger rods and cones vitreous humor rods and cones optic nerve optic disc

Eyelids Eyebrows/Eyelashes Conjunctiva canthus epicanthus cilia or eyelashes Conjunctiva canthus sclera

Eyeball Choroid coat Iris Pupil Cornea Lens

Eye Chambers Retina Ocular, Aqueous Humor Vitreous Humor Optic Nerve

Lacrimal Apparatus Structures that produce, store, and remove tears lacrimal glands lacrimal fluid lacrimation

Ears auditory audi/o and audit/o acoustic ot/o

Outer or External Ear pinna or auricle auditory canal cerumen

Middle Ear tympanic membrane auditory bones eustacian tube oval window malleus incus stapes eustacian tube oval window

Inner Ear cochlea semicircular canals cochlear duct organ of Corti equilibrium

Action of Eyes Accommodation - process whereby the eyes make adjustments for seeing objects at various distances constriction or dilation of pupil changes in shape of lens Refraction - ability of lens to bend the light rays to help them focus on the retina

Refractive Errors ametropia myopia hyperopia presbyopia astigmatism

Cataract Intracapsular extraction cryoprobe Extracapsular extraction

Glaucoma Intraocular pressure miotics partial iridectomy tonometer

Strabismus Extropia esotropia amblyopia
