hearing

Which part of the ear collects and directs sound waves into the auditory canal?

• Cochlea

• Tympanic membrane

• Pinna

• Ossicles

The auditory canal is responsible for:

• Producing earwax

• Amplifying sound waves

• Channelling sound waves to the eardrum

• Sending signals to the brain

1. Which part of the ear is filled with fluid and contains the organ of Corti?
   

• 1. Cochlea

• 1. Tympanic membrane

• 1. Auditory canal

• 1. pinna

1. The Eustachian tube connects the middle ear to the:
   

• 1. Nasal cavity

• 1. Throat

• 1. Outer ear

• 1. Cochlea

1. The semicircular canals in the inner ear are responsible for:
   

• 1. Hearing

• 1. Balance

• 1. Amplifying sound

• 1. Transmitting sound waves

Sound waves are converted into mechanical vibrations by the:

• Cochlea

• Tympanic membrane

• Ossicles

• Pinna

6. Which part of the ear amplifies sound vibrations?
   A. Cochlea
   

• 6. Cochlea

• 6. Ossicles

• 6. Auditory nerve

• 6. Eustachian tube

The organ of Corti is responsible for:

• Detecting sound vibrations

• Maintaining balance

• Amplifying sound

• Equalizing pressure

The correct sequence of structures through which sound waves travel in the ear is:

• Pinna → Auditory canal → Tympanic membrane → Ossicles → Cochlea

• Pinna → Cochlea → Ossicles → Tympanic membrane → Auditory canal

• Cochlea → Ossicles → Tympanic membrane → Auditory canal → Pinna

• Ossicles → Cochlea → Pinna → Auditory canal → Tympanic membrane

16. Which part of the ear is responsible for detecting rotational movement?
    

• 16. Cochlea

• 16. Semicircular canals

• 16. Tympanic membrane

• 16. Semicircular canals
