FAQs on Fun Video: The Ear (Parts of an Ear & Mechanism of Hearing) Video Lecture - NEET

1. What are the three main parts of the ear?

Ans. The three main parts of the ear are the outer ear, the middle ear, and the inner ear. The outer ear consists of the pinna, ear canal, and eardrum. The middle ear contains the three smallest bones in the body: the hammer, anvil, and stirrup. The inner ear consists of the cochlea, semicircular canals, and vestibule.

2. How does the mechanism of hearing work?

Ans. The mechanism of hearing starts with sound waves entering the outer ear and traveling through the ear canal, causing the eardrum to vibrate. These vibrations are then transferred to the three tiny bones in the middle ear, which amplify the sound. The vibrations are further transmitted to the cochlea in the inner ear, where they stimulate tiny hair cells. These hair cells convert the vibrations into electrical signals that are sent to the brain through the auditory nerve, allowing us to perceive sound.

3. What is the function of the cochlea in the ear?

Ans. The cochlea is a spiral-shaped structure in the inner ear that plays a crucial role in the process of hearing. It is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. The cochlea contains thousands of tiny hair cells that are sensitive to different frequencies of sound. When these hair cells are stimulated by sound vibrations, they generate electrical signals that are sent to the brain through the auditory nerve, enabling us to hear and distinguish various sounds.

4. How does the outer ear help in the process of hearing?

Ans. The outer ear plays a significant role in the process of hearing. The pinna, the visible part of the outer ear, helps to collect sound waves from the surrounding environment and direct them into the ear canal. The ear canal, a tube-like structure, channels the sound waves towards the eardrum. The eardrum, a thin membrane, vibrates in response to the sound waves, amplifying them and transmitting them further into the middle ear. In summary, the outer ear acts as a funnel, gathering and guiding sound waves into the ear.

5. What is the purpose of the three smallest bones in the middle ear?

Ans. The three smallest bones in the middle ear, namely the hammer, anvil, and stirrup (also known as the malleus, incus, and stapes), serve the vital function of amplifying sound vibrations. When the eardrum vibrates in response to sound waves, it moves the hammer bone. The hammer bone then transmits these vibrations to the anvil bone, which, in turn, moves the stirrup bone. This chain of vibrations serves to amplify the sound waves before they reach the cochlea in the inner ear, enhancing our ability to hear faint sounds.
