Chapter 29 Eyes, Ears, and Nose Pharmacy Technician
| Aqueous humor: | A watery fluid, such as that found in the eyes. |
| Auditory ossicles: | Three small bones (the malleus, incus, and stapes) that transmit sound vibrations from the eardrum to the oval window of the ear. |
| Auditory tube: | The eustachian tube; the structure linking the pharynx to the middle ear. |
| Cerumen: | The soft brownish-yellow wax secreted by ceruminous glands in the auditory canal of the external ear. |
| Choroid: | The thin, posterior membrane in the middle layer of the eye. |
| Ciliary body: | A thickened portion of the vascular tunic of the eye that connects the choroid with the iris. |
| Cochlea: | The auditory portion of the inner ear; made up of coiled, tapered tubes. |
| Cones: | Specialized receptor cells in the retina that perceive colors and bright light. |
| Conjunctivitis: | An inflammation of the outermost layer of the eye and inner surface of the eyelid, usually due to an allergic reaction or an infection; commonly called “pink eye.” |
| Cornea: | The transparent front part of the eye covering the iris, pupil, and anterior chamber; it helps the eye to focus and is known as the “window” of the eye. |
| Eardrum: | The tympanic membrane; a structure that transmits sound from the air to the ossicles inside the middle ear—it separates the external ear from the middle ear. |
| External acoustic meatus: | An S-shaped tube in each ear that leads inward through the temporal bone. |
| Fovea centralis: | A small depression in the center of the macula that has the greatest visual acuity and lies directly opposite to the pupil. |
| Labyrinth: | A system of fluid passages in the inner ear, including the semicircular canals and the cochlea. |
| Macula lutea: | A small yellowish area containing the fovea centralis, located near the center of the retina, at which visual perception is most acute. |
| Macular degeneration: | A condition primarily affecting older adults, wherein the macula area of the retina of the eye becomes thinner and atrophies, sometimes resulting in bleeding; it often results in loss of vision. |
| Optic disc: | A small oval-shaped area on the retina marking the site of entrance into the eyeball of the optic nerve. |
| Organ of Corti: | The spiral-shaped organ of the inner ear that contains auditory “hair cells” that provide the sense of hearing. |
| Ototoxicity: | The property of being toxic to the ears. |
| Oval window: | A membrane-covered opening leading from the middle ear to the vestibule of the inner ear. |
| Pupil: | The black circular center of the eye; it opens and closes when muscles in the iris expand and contract in response to light. |
| Retina: | The sensitive membrane in the inner layer of the eye; it decodes light waves and transmits information to the brain |
| Rods: | Specialized receptor cells in the retina that perceive dim light but not colors. |
| Saccule: | The smaller of the two membranous sacs in the vestibule of the inner ear. |
| Sclera: | A thick, tough, white membrane in the outer layer of the eye. |
| Semicircular canals: | Three interconnected tubes inside the inner ear that are filled with a fluid called endolymph; they are part of the labyrinth of the ear. |
| Suspensory ligaments: | Ligaments that support organs or body parts, such as those that hold the lenses of the eyes in place. |
| Utricle: | The larger of the two membranous sacs in the vestibule of the inner ear; it is connected with the semicircular canals. |
| Uvea: | The region of the eye containing the iris, choroid membrane, and ciliary bodies. |
| Vitreous humor: | The semisolid fluid behind the iris of the eye. It gives the eye its firmness and shape. |
| Eyes three distinct layers are: | Sclera (outer layer), uvea (middle layer), and retina (inner layer). |
| Iris: | Colored portion of the eye. |
| Lens: | A clear, biconvex structure that assist in focusing. |
| Accommodation: | Is the lens ability to focus on an objects at different distances. |
| Auricle: | Outer ear. |
| Cilia: | Tiny hair in the ear. |
| Mallus: | One of the auditory ossicles; looks like a mallet. |
| Incus: | One of the auditory ossicles; looks like an anvil. |
| Stapes: | One of the auditory ossicles; looks like a stirrup |
