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.

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.
