Trivia Quiz On Ear Function
This quiz test comprehension of how the ear functions.
Questions and Answers
- 1.
In the nerve cells, the sound waves change to ___________________that race along nerve cells to the brain.
- A.
Vibrations
- B.
Electric signals
- C.
Molecules
- D.
Energy
Correct Answer
B. Electric signalsExplanation
Sound waves are converted into electric signals in nerve cells. These electric signals then travel along the nerve cells to reach the brain. This conversion allows the brain to interpret and perceive sound. Vibrations, molecules, and energy are not directly involved in this process.Rate this question:

Which parts helps us keep our balance?
- A.
Middle ear
- B.
Inner ear
- C.
Middle ear, brain
- D.
Inner ear, brain
Correct Answer
D. Inner ear, brainExplanation
The inner ear and brain are responsible for helping us keep our balance. The inner ear contains structures such as the semicircular canals and vestibule, which detect changes in head position and movement. These signals are then sent to the brain, which processes the information and sends signals to the muscles to adjust and maintain balance. This coordination between the inner ear and brain is crucial for our ability to stay balanced and oriented in our surroundings.Rate this question:

The cochlea is filed with the following:
- A.
Liquid
- B.
Liquid, hair like cells
- C.
Hair like cells
- D.
Liquid, hair cells, bone
Correct Answer
B. Liquid, hair like cellsExplanation
The cochlea is filled with liquid and hair-like cells. The liquid, known as endolymph, plays a crucial role in transmitting sound vibrations to the hair cells. These hair-like cells, called stereocilia, are responsible for converting these vibrations into electrical signals that can be interpreted by the brain as sound. The combination of liquid and hair-like cells allows for the proper functioning of the cochlea in the process of hearing.Rate this question:

Why can we hear sounds underwater?
Correct Answer
Sound travels through waterExplanation
Sound is a mechanical wave that requires a medium to travel through. Water is a denser medium than air, which allows sound waves to travel more efficiently. When sound waves enter water, they cause the water molecules to vibrate, transferring the energy of the sound wave. These vibrations then travel through the water, reaching our ears and allowing us to hear the sound.Rate this question:

What does the eardrum do when sounds hit it?
Correct Answer
vibrate
vibratesExplanation
The eardrum plays a crucial role in the process of hearing. When sound waves reach the eardrum, it vibrates or moves back and forth. These vibrations are then transmitted to the tiny bones in the middle ear, which amplify the sound and send it to the inner ear. From there, the sound is converted into electrical signals that can be interpreted by the brain. Therefore, the correct answer is "vibrate" or "vibrates" as the eardrum responds to sounds by vibrating.Rate this question:

The following are parts of the ear: stapes, malleus, cochlea. Which part below is NOT a part of the ear.
- A.
Incus
- B.
Eardrum
- C.
Diaphram
Correct Answer
C. DiaphramExplanation
The question asks for the part of the ear that is NOT included in the given list. The options provided are incus, eardrum, and diaphragm. The correct answer is diaphragm because it is not a part of the ear. The diaphragm is a muscle located below the lungs that helps in the process of breathing, and it is not associated with the ear's anatomy or function.Rate this question:

What are the 3 main parts of the ear?
Correct Answer
middle
inner
outerExplanation
The ear is divided into three main parts: the outer ear, the middle ear, and the inner ear. The outer ear consists of the visible part of the ear, called the pinna, and the ear canal. Its main function is to collect sound waves and direct them towards the middle ear. The middle ear contains the eardrum and three tiny bones called ossicles, which transmit sound vibrations from the eardrum to the inner ear. The inner ear is responsible for converting sound vibrations into electrical signals that can be processed by the brain. It consists of the cochlea, which is responsible for hearing, and the vestibular system, which helps with balance and orientation.Rate this question:

Which part of our bodies help us to hear?
- A.
Ear
- B.
Brain
- C.
Ear, brain, nerves
Correct Answer
C. Ear, brain, nervesExplanation
The ear, brain, and nerves all work together to help us hear. The ear collects sound waves and converts them into electrical signals that are sent to the brain. The brain then processes these signals and interprets them as sound. Nerves play a crucial role in transmitting these signals between the ear and the brain, allowing us to perceive and understand sounds.Rate this question:

What is the ear part that is shaped like a snail?
- A.
Ear drum
- B.
Stapes
- C.
Cochlea
Correct Answer
C. CochleaExplanation
The cochlea is the correct answer because it is the part of the ear that is shaped like a snail. It is a spiral-shaped, fluid-filled structure in the inner ear that is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. The cochlea plays a crucial role in our ability to hear and is one of the key components of the auditory system.Rate this question:
