#1
Which part of the ear collects sound waves?
External auditory canal
ExplanationExternal auditory canal collects sound waves and directs them towards the eardrum.
#2
What is the function of the eardrum?
To transmit vibrations to the middle ear
ExplanationThe eardrum transmits vibrations from sound waves to the middle ear for further processing.
#3
Which structure of the ear is responsible for maintaining balance?
Semicircular canals
ExplanationSemicircular canals play a crucial role in maintaining balance and spatial orientation.
#4
What is the medical term for the ear canal?
External auditory canal
ExplanationThe medical term for the ear canal is the external auditory canal.
#5
Which part of the ear contains the sensory cells responsible for hearing?
Cochlea
ExplanationThe cochlea houses sensory cells that detect sound vibrations and convert them into electrical signals for the brain.
#6
What is the function of the ossicles in the middle ear?
To transmit vibrations to the inner ear
ExplanationOssicles amplify and transmit vibrations from the eardrum to the inner ear.
#7
Which structure is responsible for equalizing pressure between the middle ear and the outside environment?
Eustachian tube
ExplanationThe Eustachian tube equalizes pressure between the middle ear and the external environment.
#8
What is the role of the vestibular system in the ear?
To maintain balance and spatial orientation
ExplanationThe vestibular system helps in maintaining balance and spatial orientation.
#9
What is the function of the auditory nerve?
To transmit sound signals to the brain
ExplanationThe auditory nerve transmits electrical signals representing sound from the inner ear to the brain.
#10
What is presbycusis?
Loss of hearing due to aging
ExplanationPresbycusis is the gradual loss of hearing that occurs with aging.
#11
What is the term for the tiny hairs in the cochlea that detect sound vibrations?
Hair cells
ExplanationHair cells in the cochlea detect and transmit signals in response to sound vibrations.
#12
Which cranial nerve is primarily responsible for transmitting auditory information to the brain?
Vestibulocochlear nerve
ExplanationThe Vestibulocochlear nerve is primarily responsible for transmitting auditory information from the ear to the brain.
#13
What is the scientific name for the ear infection commonly known as 'swimmer's ear'?
Otitis externa
ExplanationOtitis externa, commonly known as 'swimmer's ear,' is the scientific name for an ear infection.
#14
Which part of the ear is responsible for converting sound vibrations into electrical signals sent to the brain?
Cochlea
ExplanationThe cochlea converts sound vibrations into electrical signals sent to the brain for processing.
