external auditory canal

one of three anatomic parts of the ear; it contains the pinna the ear canal and the external portion of the tympanic membrane

external ear

a group of conditions that lead to increased intraocular pressure causing damage to the optic nerve; a leading cause of blindness

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

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

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
