What is the physiology of the ear?
The ear is the organ of hearing; it enables the perception of sound. Hearing is the process by which the ear transforms sound vibrations in the external environment into nerve impulses that are conveyed to the brain, where they are interpreted as sounds.
What is the eardrum function?
The eardrum is a thin flap of skin that is stretched tight like a drum and vibrates when sound hits it. These vibrations move the tiny bones of the middle ear, which send vibrations to the inner ear. From the inner ear, the message is sent to the brain, which says, “Hey!
What is an eardrum quizlet?
eardrum – (also called the tympanic membrane) a thin membrane that vibrates when sound waves reach it. Eustachian tube – a tube that connects the middle ear to the back of the nose; it equalizes the pressure between the middle ear and the air outside.
What is eardrum in psychology?
The Eardrum, or tympanic membrane, is a thin flap of skin at the end of the ear canal. When sound waves hit the eardrum it creates vibrations that travel through the middle ear to the inner ear. The inner ear then sends a message to our brain about what we are hearing.
Why is the ear shaped like it is?
The swirly shape of the ear leads sound down into the auditory canal, which acts as an amplifier. “Humans have a natural amplification in the 2,000- to 4,000-Hz range, which is where the difference between consonant and vowel sounds comes into play,” says Dr.
What role does the inner ear play in hearing quizlet?
a tiny, U-shaped bone that passes vibrations from the stirrup to the cochlea at the oval window. The inner ear is the portion of the ear, which is responsible for translating the message and sending it to the brain where it can be interpreted.
What role does the inner ear play in hearing sounds quizlet?
Vibrations move via the oval window through the fluid in the cochlea (inner ear), which stimulates tiny hair cells. > Vibrations are transformed into electrical impulses that are perceived by the brain as sound.
What is sense of hearing called?
Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. The academic field concerned with hearing is auditory science.
How do you blow out an eardrum?
Some people are surprised to hear air coming out their ear when they blow their nose. Forcefully blowing your nose causes air to rise up to fill the space in your middle ear. Normally this will cause the eardrum to balloon outward. But if there is a hole in the eardrum, air will rush out.
What causes ear drum pain?
Ruptured ear drums and airplane ear are additional ear conditions that can directly lead to sharp pain in the ears. Other indirect causes of ear pain include toothaches or certain jaw conditions, such as temporomandibular joint (TMJ) syndrome.
What do people usually feel when they have a ruptured eardrum?
Earache. The first sign of a ruptured eardrum is generally ear pain.
What to do for a punctured eardrum?
Treatment for a punctured eardrum is often relatively straightforward. Patients are generally asked to keep the ear dry and clean. Cotton balls can be placed in the ear to prevent liquid or debris from entering the middle ear. Patients are generally advised not to swim or submerge the head in water.
