Click on the flashcard to see the answer
What are the three main parts of the human ear?
The three main parts of the human ear are the outer ear, middle ear, and inner ear.
What is the function of the outer ear?
The outer ear collects sound waves and directs them into the ear canal.
Which part of the ear vibrates in response to sound waves?
The eardrum (tympanic membrane) vibrates in response to sound waves.
What is the function of the middle ear?
The middle ear amplifies and transmits the sound vibrations from the outer ear to the inner ear.
Name the three smallest bones in the human body that are located in the middle ear.
The three smallest bones in the human body are the hammer (malleus), anvil (incus), and stirrup (stapes). They are located in the middle ear.
What is the function of the inner ear?
The inner ear converts sound vibrations into electrical signals and sends them to the brain for processing.
Which part of the ear contains the cochlea?
The cochlea is located in the inner ear.
What is the role of the cochlea in the hearing process?
The cochlea converts sound vibrations into electrical impulses that can be interpreted by the brain as sound.
What is the function of the auditory nerve?
The auditory nerve carries electrical signals from the inner ear to the brain, allowing us to perceive and interpret sound.
What is the purpose of the Eustachian tube?
The Eustachian tube helps equalize air pressure between the middle ear and the atmosphere.
How does the brain interpret different pitches of sound?
The brain interprets different pitches of sound based on the specific frequency of the sound waves.
What is the maximum decibel level that the human ear can tolerate without experiencing pain?
The human ear can tolerate sound levels up to around 85 decibels without experiencing pain.
What is the medical term for the condition of ringing in the ears?
The medical term for the condition of ringing in the ears is tinnitus.
How does the brain determine the direction of sound?
The brain determines the direction of sound by comparing the arrival time and intensity of sound waves at each ear.
What are the potential consequences of prolonged exposure to loud noises?
Prolonged exposure to loud noises can lead to hearing loss, tinnitus, and other auditory disorders.
