What is the part of the ear that is shaped like a snail?
Correct Answer
C. Cochlear
Explanation
The cochlear is the part of the ear that is shaped like a snail. It is a spiral-shaped structure located in the inner ear and is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. The cochlear is filled with fluid and contains tiny hair cells that are essential for hearing. These hair cells detect the vibrations and send signals to the brain, allowing us to perceive and interpret different sounds.
2.
What is the vocabulary that means tiny particles of materials such as water or air?
Correct Answer
B. Molecules
Explanation
Molecules are the correct answer because they are made up of atoms bonded together. Molecules can be composed of various types of atoms, including those found in water and air. Therefore, molecules represent tiny particles of materials such as water or air.
3.
Use your vocabulary word from the story to fill in the blank below.
It is up to your brain to_________________________the signals and tell you the different sounds that you hear.
Correct Answer
Interpret
Explanation
The word "interpret" means to understand or make sense of something. In this context, it refers to the brain's ability to analyze and decipher the signals it receives, allowing us to recognize and differentiate between various sounds. The brain processes these signals and translates them into meaningful information, enabling us to perceive and comprehend the auditory world around us.
4.
Which part of the ear do waves hit?
Correct Answer
D. Eardrum
Explanation
Waves hit the eardrum. The eardrum, also known as the tympanic membrane, is a thin, cone-shaped membrane that separates the outer ear from the middle ear. When sound waves enter the ear, they cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where they are further amplified and transmitted to the inner ear.
5.
Which part of the ear helps us to keep our balance?
Correct Answer
C. Inner Ear
Explanation
The inner ear helps us to keep our balance. It contains the vestibular system, which consists of fluid-filled canals and sacs that detect changes in head position and movement. These structures send signals to the brain, allowing us to maintain our balance and coordinate our movements. The inner ear also plays a role in hearing, as it contains the cochlea, which converts sound vibrations into electrical signals that can be interpreted by the brain.
6.
In the ___________________cells, the sound waves change to electric signals in the brain.
Correct Answer
C. Nerve
Explanation
The correct answer is "nerve" because the nerve cells in the inner ear are responsible for converting sound waves into electric signals that can be processed by the brain. These nerve cells, also known as auditory nerve fibers, transmit the electrical signals from the cochlea to the brain, allowing us to perceive and interpret sound. The inner ear contains the cochlea, which is the main organ for hearing, and the nerve cells within the cochlea play a crucial role in the conversion of sound waves into electrical signals.
7.
What is the name of the 3rd ear part?
Correct Answer
B. Outer Ear
Explanation
The outer ear is the part of the ear that is visible on the outside of the head. It consists of the pinna (the visible part) and the ear canal. The outer ear's main function is to collect sound waves and direct them into the ear canal, where they will travel further into the middle and inner ear for processing.
8.
What is the name of the 12th ear part?
Correct Answer
C. Eustachian Tube
Explanation
The Eustachian Tube is the correct answer because it is the 12th part of the ear. It is a narrow tube that connects the middle ear to the back of the throat. Its main function is to equalize the pressure between the middle ear and the atmosphere, allowing the eardrum to vibrate properly and preventing discomfort or damage to the ear.
9.
The Tympanic Membrane is another name for which ear part?
Correct Answer
D. Eardrum
Explanation
The Tympanic Membrane is another name for the Eardrum.
10.
What is the name of the 6th ear part?
Correct Answer
B. Hammer
Explanation
The correct answer is "Hammer." The hammer, also known as the malleus, is one of the three small bones in the middle ear. It is connected to the eardrum on one end and the anvil (incus) on the other end. The hammer plays a crucial role in transmitting sound vibrations from the eardrum to the inner ear, where they are converted into electrical signals that the brain can interpret.
11.
What is the name of the 4th ear part?
Correct Answer
D. Eardrum
Explanation
The eardrum, also known as the tympanic membrane, is a thin, cone-shaped membrane located in the middle ear. It separates the outer ear from the middle ear and vibrates in response to sound waves, transmitting them to the middle ear. The eardrum plays a crucial role in the process of hearing by converting sound waves into mechanical vibrations that can be further processed by the auditory system.
12.
_______________________produces sounds.
Correct Answer
Vibrations
Explanation
Vibrations are known to produce sounds. When an object vibrates, it creates disturbances in the surrounding air molecules, causing them to vibrate as well. These vibrations are then transmitted as sound waves, which can be detected by our ears and interpreted as sound. Therefore, vibrations are directly linked to the production of sounds.
13.
Besides our ears the______________________and ____________________helps us to hear properly.
Correct Answer
nerves, brain
Explanation
Our ears are responsible for capturing sound waves, but the process of hearing involves more than just the ears. The nerves play a crucial role in transmitting these sound signals from the ears to the brain. The nerves carry the electrical signals generated by the sound waves to the brain, where they are interpreted and processed. The brain then makes sense of these signals, allowing us to understand and perceive sound. Therefore, both the nerves and the brain are essential in helping us hear properly.
14.
______________________is the vocabulary word that tells us what the ear does with the sounds that enter our ears.
Correct Answer
funnels
Explanation
The word "funnels" is the vocabulary word that tells us what the ear does with the sounds that enter our ears.
