EENT Flashcards
are a key sensory organ, feeding information to your brain about the outside world.
Eye
Parts of the eye
Cornea
Sclera
Conjunctiva
Iris
Pupil
Lens
Vitreous Humor
Retina
Macula
Optic Nerve
External Muscles
This protects the inside of your eye like a windshield.
Cornea
a part of the eye that bends light as it enters your eyes
Cornea
This is the white part of your eye that forms the general shape and structure of your eyeball
Sclera
This clear, thin layer covers the sclera and lines the inside of your eyelids.
Conjunctiva
This parts contains the muscles that control the size of your pupil. Its also responsible for your eye color
Iris
Colors of the iris
Brown, blue, Green
This is the black circle inside the iris. its like an adjustable window inside of your eye. it widens and narrows to control how much light enters your eye
Pupil
This focuses light that enters your eye and directs it to the back of your eye
Lens
This clear, gel-like fluid fills the space between the lens and retina. it helps your eye hold its shape.
Vitreous Humor
This thin layer of light sensitive cells at the back of your eyes converts light into electrical signals. It contains rods (which help you see in low light) and cones (helps you see colors)
Retina
a part of the retina that helps you see in low light
Rods
a part of the retina that helps you see color
Cones
Where are cones and rods found
In the Retina
This small area of your retina is key to your vision. its responsible for the center of your visual field. It also helps you see color and fine details
Macula
This connects your retinas to your brain. It’s like the data cable that carries signals from your eyes, with connection points linking to multiple brain areas.
Optic nerve
These controls your eye’s position, alignment and movement. They also contribute to your eye’s shape, which is part of your ability to switch your vision’s focus between near and far objects
External Muscles
are paired organs located o n each side of your head, which help with hearing and balance.
Ear
Three main parts of the ear
Outer ear
Middle ear
Inner ear
What separates the outer and middle ear
Tympanic membrane (eardrum)
the part of your ear that is most visible. It’s what most people mean when they say “ear”. consists of ridged cartilage and skin, and it contains glands that secrete earwax, its funnel shaped canal leads to your eardrum, or tympanic membrane.
Outer ear (external ear)
What is the outer ear also called
The auricle or pinna
begins on the other side of your tympanic membrane (eardrum).
Middle Ear
three tiny bones in the middle ear.
Malleus
Incus
Stapes
They transfer sound vibrations from your eardrum to you inner ear.
Malleus, Incus, and stapes.
What does the middle ears house? that help equalize the air pressure in your ears
Eustachian Tubes
purpose of Eustachian tubes
Help equalize the air pressure in your ears
contains two main parts, Cochlea and semicircular canals.
Inner ear
The hearing organ, this snail shaped structure contains two fluid filled chambers with tiny hairs.
Cochlea
Also known as the labyrinthine, are responsible for balance. They tell your which direction your head is moving
Semicircular canals
The nose is made up of
External Meatus
External Nostrils
Septum
Nasal passages
Triangular shaped projection in the center of the face
External Meatus
Two chambers divided by the septum
External Nostrils
Made up mainly of cartilage and bone and covered by mucous membranes. The cartilage also gives shape and support to the outer part of the nose
Septum
Passages that are lined with mucous membranes and tiny hairs (cilia) that help to filter the air
Nasal passages
Helps filter the air
cilia
The throat is made up of
Tonsils and Adenoids
Voice box
Epiglottis
Both are made up of lymph tissue and are located at the back of the throat.
Tonsils and adenoids
located all the way at the back of the nose at the very top of the throat.
Adenoids
Are in the back of the mouth on either side of the throat, They protect against infection but have minimal function after childhood
Tonsils
Is a cylindrical grouping of cartilage, muscles, and soft tissue that contains the vocal cords. The vocal cords are the upper opening into the windpipe (trachea), the passageway to the lungs
Voice box (Larynx)
a flap of soft tissue just above the vocal cords to prevent food and irritants from entering the lungs
Epiglottis
a ring like muscular tube, the passageway of food, air, and liquid. it also helps in forming speech
Throat
Physical assessment interview data (subjective)
To investigate a complaint about the eyes, ears, nose and throat, ask about the onset, location, duration, and characteristics of the symptom as well as what aggravates and relieves it
History of:
Corrective lenses, blurred vision, blind spots, floaters, double vision, eye injury, eye surgery.
Ear discharge, vertigo, ear problem, or injury
Bleeding, sore gums, tongue ulcers, bad taste, bad breath, toothaches, hoarseness, facial swelling.
Physical assessment Physical data (objective)
Inspection, palpation, percussion, auscultation
The degree of detail the eye can discern an image
Visual acuity
