tympanic membrane AKA
eardrum
structure at the entrance to the inner ear; filled with fluid
vestibule

ethmoid sinuses
sinuses above each eyebrow in the frontal bone of the cranium
frontal sinuses
larges of the sinuses
maxillary sinuses
hollow cavity within a cranial or facial bone; lined with mucosa
sinus
sinuses in the sphenoid bone posterior to the nasal cavity and near the pituitary gland of the brain
sphenoid sinuses
one nostril; the opening into the nasal cavity
naris
hollow area inside the nose that is formed by the ethmoid and maxillary bones
nasal cavity
wall of cartilage and bone that divides the nasal cavity into right and left sides
nasal septum
three long projections of bone covered with mucoase; that jut into the nasal cavity

turbinates AKA
nasal conchae
bone that divides the nasl cavity from the oral cavity
hard palate
lines the cheek area of the oral cavity
buccal mucosa
hollow area inside of the mouth that contains the tongue; teeth; hard and soft palates; and uvula; lined with oral mucosa

soft tissue extension of the hard palate at the back of the troat. It ends with the uvula
soft palate
moveable joint where ligaments attach each end of the mandible to the temporal bones of the cranium
tempro-mandibular joint

tongue
lymphoid tissue in the nasopharynx
adenoids
lymphoid tissue located on both sides of the base of the tongue in the laryngopharynx

lymphoid tissue in the oropharynx on either side of the soft palate
palatine tonsils
pharynx
the throat
lid like structure that covers the top of the larynx during swallowing
epiglottis
traingular structure in the anterior neck
larynx
connective tissue bands in the glottis that vibrate and produce sounds during speaking and singing
vocal chords
cerumen; epithelial cells; and hair form a mass that occludes the external auditory canal. Occurs most commonly in order adults because of dry skin; thick cerumen; growth of hair in the external auditory canal and/or the presence of a hearing aid

bacterial or viral infection of the semicircular canals; causing severe vertigo
labyrinthitis
labyrinthitis word breakdown
labyrinth/o- labyrinth (of the inner ear) -it is inflammation of; infection of
edema of the semicurcular canals with destruction of the cochlea; causing tinnitus; vertigo; hearing loss; and nystagmus
