Special Senses Eyes and Ears Flashcards
a medical specialty concerned with the eyes, the organs of sight
is the branch of medicine concerned with diagnosis and treatment of eye disorders.
opthamology
The medical specialist in ophthalmology is called an ophthalmologist.
jobs of an opthamologist include:
- eye correction surgery
- prescribing corrective lenses
- cornea transplantation
- cataract removal
- repair of ocular muscle dysfunction
- glaucoma treatment
- lens removal
- radial keratotomy.
An exam from an opthamologist can also detect other health conditions such as:
- diabetes
- stroke
- heart disease
- cancer
- high cholesteral
- lupus
- multiple sclerosis
- myasthenia gravis
- lyme disease
- rheumatoid arthritis
- thyroid disease

a medical specialty is concerned with the ears, the organs of hearing
otolaryngology
These two eye specialists can provide corrective lenses for the eyes, they are not medical doctors, but they are licensed to examine and test the eyes and treat visual defects by prescribing corrective lenses.
optometrist and optician
is the oldest medical specialty in the United States Fifty years ago it **was **practiced along with ophthalmology During that time, the medical practice consisted mainly of removing tonsils and adenoids and irrigating (cleansing a canal by flushing it with water or other fluids) the sinuses and ear canals.
Otolaryngology
greatly expanded to include medical and surgical management of patients with disorders of the ear, nose, and throat and related structures of the head and neck region. These specialists are called:
ENT physicians, or otolaryngologists
ENT physicians commonly treat disorders related to the following:
- sinuses
- allergies
- disorders of he sense of smell
are receptor organs that provide vision
constructed to detect stimuli in the environment and to transmit those observations to the brain for visual interpretation
eyes
otolaryngologist or ENT Physicians treast the following symptoms and conditions:
- hoarseness,
- hearing difficulty
- breathing difficulty
- swelling around the head or the neck
- sleep disorders (sleep apnea)
- snoring disorders
EYES
a thin layer of tissue that lines the back of the eye on the inside. It is located near the optic nerve its is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition.
retina
retin/o
the white part of your eye that wraps around your eyeball and protects it from injury
sclera
scler/o
the part of your eye between the sclera and the retina that contains blood vessels and connective tissue it is part of the uvea, and it helps nourish the retina and regulate temperature
choroid
choroid/o
a circular, colored structure that sits in front of the lens within the coronal plane towards the front of the eye, it is unbound in its middle to allow the pupil to change size, this structure is connected to the ciliary body—the part of the eye that produces the eye’s fluid
iris
irid/o
the clear, protective layer of your eye that helps you see and keeps out harmful substances.
cornea
corne/o or kerat/o
eyelid
blephar/o
the black hole in the middle of your iris that lets light into your eye. It changes size in response to changes in light and is controlled by muscles in your iris
pupil
cor/o, core/o, pupill/o
an ellipsoid structure in the eyeball that transmits and focuses the light onto the retina
lens
phac/o
a thin, clear membrane that protects your eye and keeps it lubricated
conjunctiva
conjunctiv/o
also known as the second cranial nerve, cranial nerve II, or simply CN II, is a paired cranial nerve that transmits visual information from the retina to the brain
optic nerve
organs that enable us to hear and maintain balance
ear
ot/o
Name the three divisions of the ear
external: conduct sound waves through the ear
middle:conduct sound waves through the ear
inner ear: contains auditory structures that receive sound waves and transmit them to the brain for interpretation
This part of the ear contains specialized receptors that maintain balance and equilibrium in response to fluctuations in body position and motion
the inner ear
EAR STRUCTURES
also known as the eardrum, which receives sound vibrations from the outer air and transmits them to the middle ear
tympanic membrane
myring/o or tympan/o
