Question

State whether the following statements are true or false.If false,correct them by changing any single word in each
a. Deafness is caused due to rupturing of the pina.
b. Semicircular canals are concerned with Static(positional) balance.

Answer 1

Deafness is the absolute impossibility of hearing sound. There are several causes of deafness and hearing loss and it can occur at any age. The semicircular canals or semicircular ducts are three interconnected semicircular tubes located in the innermost portion of each ear, the inner ear.

Complete Answer:
The statement (A) is False.
- The only noticeable portion of the ear (the auricle) with its distinctive helical form is the pinna. It is the first part of the ear that uses sound to respond. The role of the pinna is to behave as a kind of funnel that helps to further steer the sound into the ear.
- The sound waves would have taken a more direct path through the auditory canal without this funnel.If the sound waves have gone through the pinna, until reaching the eardrum, also known as the tympanic membrane, they travel two to three centimetres through the auditory canal.
- According to the sound waves, the eardrum vibrates and transmits them across the middle ear. The eardrum is responsible for the sensitivity of the ear.
Therefore, the correct statement: The rupture of the tympanic membrane (ear drum) causes deafness.

The statement (B) is False
- Together, the semicircular canals and the inner ear's vestibule help to preserve the body's balance and balance. There are three semicircular canals and the vestibule (which has the saccule and utricle) in these two systems of the inner ear.
- Both static and dynamic harmony are retained by the ear. Static equilibrium is the preservation of the correct location of the head in response to linear motion changes, such as walking.In response to rotational motion, such as spinning, dynamic equilibrium is the preservation of the correct head position.
- Between the semicircular canals and the cochlea (eardrum) lies the vestibule. The vestibule is responsible for preserving static balance, while dynamic equilibrium is maintained by the semicircular canals.

The correct statement is Semicircular canals are concerned with Dynamic Balance.

Note: Hearing loss is a range at one end with mild hearing problems and deep, permanent deafness at the other. If something prevents sound waves from reaching the inner ear, conductive hearing loss occurs. Damage to the inner ear or nerves that transmit sound to the brain causes sensorineural hearing loss. It is more probable that sensorineural hearing loss is permanent and causes deafness. A mixture of conductive and sensorineural hearing loss may often happen.
