Study Notes
Audiologist
- Term components: Audi/o/logist; Audi = hearing (WR), o = combining vowel (CV), logist = specialist (S).
- Definition: Specialist who diagnoses and treats hearing disorders.
Ophthalmoscopy
- Term components: Ophthalm/o/scopy; Ophthalm = eye (WR), o = combining vowel (CV), scopy = process of viewing (S).
- Definition: Process of viewing the eye.
Tympanoplasty
- Term components: Tympan/o/plasty; Tympan = tympanic membrane (WR), o = combining vowel (CV), plasty = surgical repair (S).
- Definition: Surgical repair of the tympanic membrane.
Taste Transmission
- Papillae on the tongue contain structures necessary for taste.
- Taste buds within papillae house specialized receptor cells for taste transduction.
- Receptor cells respond to food chemicals, releasing neurotransmitters based on chemical concentration.
- Originally, four primary tastes: sweet, salty, sour, and bitter.
- Recent studies indicate potential additional tastes for fats and glutamates (found in foods like tomatoes, cheese, and mushrooms).
Olfaction (Smell)
- Based on receptors in a small area of the nasal cavity responding to chemical stimuli.
- Scent receptor messages travel to the brain, where they are interpreted and can trigger long-term memories and emotional responses.
- The olfactory bulb contains mitral cells that process signals from olfactory cells, located in the nasal epithelium.
Age-related Macular Degeneration
- Leading cause of vision loss in individuals over 50, causing blurred central vision.
- Two types:
- Dry (nonexudative): buildup of cellular debris (drusen) leads to retinal scarring.
- Wet (exudative): blood vessel growth behind the retina causes leakage, hemorrhaging, and scarring.
- No treatment for dry AMD; laser therapy may assist in treating wet AMD.
Stye
- Bacterial infection of an eyelid oil gland, resulting in a red and tender bump.
- Treatment includes warm compresses and prescription eyedrops.
Hearing Loss
- Classifications:
- Conductive hearing loss: blockage in external or middle ear inhibiting sound transmission (e.g., cerumen impaction).
- Sensorineural hearing loss: results from inner ear pathology or nerve/brain damage.
- Presbycusis: Age-related sensorineural hearing loss due to gradual nerve degeneration.
Cerumen Impaction
- Blockage from earwax buildup that can lead to hearing loss symptoms.
- Audiogram: Chart displaying hearing test results in terms of frequency and intensity of sounds.
General Note
- Interactive learning activities available to practice labeling parts of the eye and ear, as well as sensory system terminology.
Vision
- Vision is the special sense of sight, relying on the transduction of light stimuli through the eyes.
- The bony orbits provide protection and stabilization for the eyeballs, while eyelashes and eyelids block foreign particles.
- The conjunctiva covers the inner surface of the eyelids and connects to the sclera, the white part of the eye.
- The iris, a smooth muscle, regulates the size of the pupil, constricting in bright light and dilating in dim light.
- The cornea is the transparent front layer of the eye, crucial for light refraction, along with the anterior chamber and lens.
- The retina is the innermost layer containing photoreceptors that initiate visual processing; information travels via the optic nerve to the brain.
- The lacrimal gland produces tears that wash away particles; the tear duct directs these tears onto the eye's surface.
- Movement of the eye is facilitated by six extrinsic muscles that attach from the orbit to the eyeball surface.
Auditory
- Hearing converts sound waves into neural signals through the ear's anatomy.
- The Eustachian tube connects the middle ear to the pharynx, regulating air pressure on the tympanic membrane.
Touch
- Touch encompasses a general sense with receptors primarily in the skin, but also found in muscles, joints, and visceral organs.
- It detects sensations including pressure, vibration, light touch, itch, temperature, pain, and proprioception (awareness of body position).
Eye Diseases and Disorders
- Astigmatism: Blurry vision resulting from irregular curvature of the cornea or lens; treated with corrective lenses.
- Blindness: A broad term for various visual impairments from injury, disease, or congenital conditions.
- Diabetic Retinopathy: Fluid leakage from blood vessels in the retina due to diabetes, impairing vision.
- Glaucoma: A group of conditions damaging the optic nerve, often from high intraocular pressure.
- Hyperopia: Farsightedness where distant objects are clear but near objects are blurry.
- Myopia: Nearsightedness, making distant objects appear blurry.
- Nyctalopia: Difficulty seeing in low light conditions, known as night blindness.
- Macular Degeneration: Loss of central vision due to retinal damage, prevalent in older adults.
Additional Terms
- Lacrimal Gland: Produces tears, located beneath the nose's lateral edges.
- Optic Nerve: Transmits visual information from the retina to the brain.
- Ophthalmologist: A physician specializing in eye disorders and surgeries.
- Optometrist: Health care professional examining eyes for vision issues and prescribing corrective lenses.
- Otitis Externa: Inflammation or infection of the outer ear canal, commonly known as swimmer's ear.
- Otitis Media: Infection or inflammation of the middle ear, prevalent in children and linked to respiratory infections.
