Otorhinolaryngology EXAM
COMPLETE QUESTIONS AND
OUTLINED ANSWERS
Adenoid - Answer- Pharyngeal tonsil. Houses large number of white blood cells that
prevents foreign invaders from passing through pharynx
Ear - Answer- Captures sound waves, funnels them down canal, strikes tympanic
membrane vibrating to oval window. Oval window initiates vibrations in fluid inside ear.
Vibrating fluid bends hair in cochlea
Cochlea - Answer- Hair cells responsible for hearing. Shaped like a coiled snail cell
Epiglottis - Answer- Cartilage flap that sits above larynx. Tips forward to cover larynx
with each swallow
Larnyx - Answer- Contains vocal cords. Between pharynx and trachea. Aur passes
through vocal chords to produce sounds.
Tympanic Membrane (eardrum) - Answer- Located at the end of auditory canal.
Converts sounds waves striking it into vibrations that move ossicles of middle ear.
Nose - Answer- Air passes through nasal cavity into pharynx. Divided through middle by
septum. Lined by mucous membrane. Air is warmed and cleaned as it passes through.
Houses receptors for smell
Smell - Answer- Sensory receptors for smell located on roof of nasal cavity
Pharynx (throat) - Answer- Muscular tube that receives air from nasal cavity and
delivers it to the larynx. Also receives food from oral cavity and transports it to the
esophagus. Location of the tonsils. Eustachian tube opens with each swallow to
equalize air pressure in middle ear.
Sinuses - Answer- Air filled cavities located within facial bones and connected to the
nasal cavity which is lined with mucous membrane. Acts as an echo chamber for sound
production.
Trachea (windpipe) - Answer- Tube that carries air from the larynx to the lungs. Lined
with mucous membrane that warms and cleanses air.
Acoustic Neuroma - Answer- Benign tumors of auditory nerve sheath. Symptoms
include headaches, veritgo, tinnitus and hearing loss
