inner ear
the colored portion of the eye
iris
inflammation of the iris; also called the anterior uveitis
iritis
irritation and swelling in the inner ear that produces a loss of balance and possibly tinnitus dizziness loss of hearing nausea and vomiting
labyrinthitis
the structures in which tears are secreted and drained from the eye
lacrimal apparatus
swelling and inflammation of the larynx that is associated with hoarseness or loss of voice
laryngitis
a transparent body within the globe that focuses light rays
lens
a type of cellulitis that occurs on the floor of the mouth under the tongue; caused by bacteria from an infected tooth root or mouth injury
ludwig angina
the process of chewing with the teeth
mastication
an inner ear disorder in which endolymphatic rupture creates increased pressure in the cochlear duct, which then leads to damage to the organ of court and the semicircular canal; symptoms include severe vertigo, tinnitus and sensorineuronal hearing loss
meniere disease
one of the three anatomic parts of the ear; it consists of the inner portion of the tympanic membrane and the ossicles
middle ear
the separation between the right and left nostrils
nasal septum
the passage through which the tears drain form the lacrimal sacs into the nasal cavity
nasolacrimal duct
third cranial nerve that innervates muscle causing the motion of the eyeballs
oculomotor nerve
either of the second cranial nerves that enter the eyeball posteriorly through the optic foramen
optic nerve
a condition that presents as white lesions on the tongue and inner cheeks caused by the fungus candidas albicans;also called thrush
oral candidiasis
an infection within the eye socket
orbital cellulitis
a structure located in the cochlea that contains hairs that are stimulated by vibrations to form nerve impulses that travel to the brain and are perceived as sound
organ of corti
the three small bones in the inner ear that transmit vibrations to the cochlear duct as the oval window
ossicles
an infection of either the outer or middle ear cavity
otitis
an oval opening between the middle ear and the vestibule
oval window
an eye condition that results form increased pressure on the optic nerve at the rear part of the eye and symptoms to include headache, nausea, vomiting, vision loss and narrowing vision fields
papilledema
the sinuses or hallowed sections of bone in the front of the head, that are lined with mucous membrane and drain into the nasal cavity
paranasal sinuses
an infection of the eyelid
periorbital cellulitis
visualization of lateral objects while looking forward
peripheral vision
a collection of infected material around the tonsils
peritonsillar abscess
inflammation of the pharynx
pharyngitis
the large outside portion of the ear through which sound waves enter the ear; also called the auricle
pinna
the posterior area of the globe between the lens and the iris
posterior chamber
specialized connective tissue within the pulp cavity of a tooth
pulp
the circular opening in the center of the eye through which light passes to the lens
pupil
a delicate 10 layered structure of nervous tissue located in the rear of the interior of the globe that receives light and generates nerve signals that are transmitted to the brain through the optic nerve
retina
separation of the inner layers of the retina from the underlying choroid, the vascular membrane that nourishes the retina
retinal detachment
a nasal disorder generally caused by allergens which result in production of chemicals that can cause inflammation
rhinitis
the white part of the eye
sclera
an infection of the sinuses characterized by the thick nasal discharge sinus and facial pressure headache and fever
sinusitis
the movement of both eyes in unison
sympathetic eye movement
a collection of disorders that present with jaw pain, and which occur when the connection between the temporal bone and temporomandibular joint erodes or moves out of proper alignment
tmj joint disorders
the perception of sound in the inner ear with no external environmental cause; often reported as ringing in the ears, but may be roaring buzzing or clicking
tinnitus
inflammation of the tonsils
tonsillitis
bacterial infection of the trachea
tracheitis
the fifth cranial nerve where the mandibular branch provides motor innervation to the muscles of mastication
trigeminal nerve
three bony shelves that protrude from the lateral walls of the nasal cavity and extend into the nasal passageway parallel to the nasal floor; serve to increase the surface area of the nasal mucosa thereby improving the process of warming filtering and humidification of inhaled air
turbinates
a thin membrane that separates the middle ear from the inner ear and sets up vibrations in the ossicles also called the eardrum
tympanic membrane
a type of dizziness in which a person experiences the sensation of movement when standing still or the environment moving around himself; due to an inner ear disorder
vertigo
the area in the brain where signals from the optic nerve are converted into visual images
