Module 6 Eye And Ears Flashcards
How do you air pathways work?
From the outer ear to the middle of the ear to the cochlea in the inner ear
Cochlea via mechanical vibration of the skull, with almost no stimulation of the outer and middle ear. These vibrations are transmitted directly to the inner ear and cranial nerve VIII
Conductive hearing loss
Involves mechanical disfunction of the external ear
It is partial because the person is still able to here at the sound. Apple tooth is increased enough to reach the inner ear.
Cerebrum build up / foreign bodies/ otosclerosis ( a decrease in the mobility of the ossicles )
Sensorineural or perceptive hearing loss
Indicates a pathological condition of the inner ear cranial nerve viii or the auditory of the year cerebral cortex, increasing the amplitude may not allow the person to understand words
Age, infection, noise exposure
Sensorineural or perceptive hearing loss
Indicates a pathological condition of the inner ear cranial nerve viii or the auditory of the year cerebral cortex, increasing the amplitude may not allow the person to understand words
Age, infection, noise exposure
Mixed hearing loss
A mixture of both
Changes in equilibrium occur when
Three semi circular canals, become inflamed, causing the person to have vertigo
A strong, spinning Whirling sensation
Presbycusis
A gradual sensorineural lost cause by nerve degeneration in the in the ear or auditory nerve in older adults
Infants have what kind of Eustachian tubes
Wide and Short ones
Allowing more pathogens to migrate in and higher risk of ear infections
Otosclerosis is most common in adults of what age
20-40
Otitis media
Middle of the ear infection results from instruction of the Estacion tube, or nasopharynx secretions entering the middle of the year, one of the most common illnesses and children
Cerumen
Is genetically determined, can be wet or dry
Ear wax
Hearing loss is the what most common chronic condition in older adults
3rd most
Audism
Is a form of discrimination based on a persons ability to hear
Tinnitus
Ringing, crackling, or buzzing louder at night
Otorrhera
Ear discharge
What should you avoid with a person with vertigo?
Avoid tilting their head
Avoid laying them down or arising to quickly
Avoid sudden head movements
In infants and young children, what should the ear position in alignment be
The top of the pinna should be horizontally aligned with the corner of the eye to the occupants. The ear should be positioned within 10° of vertical
Battle sign indicates
Basal skull fracture
May be delayed one to three days
Bruising behind on, and in front of your ear
Do you pull up and back on the pinna in adults or children?
For adults, pull pinna up and back
For children under three pinna , straight down
A blue eardrum indicates
There’s blood in the middle of the ear
60-60 rule
No more than 60 minutes a day at 60% max volume
What should you check for in eyes
Contacts
What age does the eye ball reach adult size
8years
Presbyopia
The ones becomes more hard in class, like which decreases his ability to accommodate for near vision
Average age 40
