Brief Overview of the Ear

Fill in the blank: The ear has 3 main sections: Outer, Middle, and ______ Ear.

• Inner

• Upper

• Lower

• Central

What is the function of the outer ear?

• To collect sound waves and funnel them into the ear canal

• To process sound into electrical signals

• To balance the body

• To protect the inner ear from foreign particles

What is the function of the Tympanic Membrane (Eardrum)?

Which of the following is NOT an auditory ossicle?

• Malleus

• Incus

• Stapes

• Cochlea

What is the role of the Malleus (Hammer) in the middle ear?

• Transmits sound vibrations from the eardrum to the incus

• Amplifies sound vibrations

• Protects the inner ear from loud sounds

• Equalizes pressure in the ear

Which bone acts as a bridge between the malleus and the stapes?

• incus

• humerus

• femur

• tibia

Identify the part labeled as 'Canal' in the cat's ear anatomy.

• Canal

• Pinna

• Cochlea

• Eardrum

The function of the cochlea in the human ear is to:

• transmit sound waves to the brain

• amplify sound vibrations

• convert sound waves into electrical signals

• balance the pressure in the ear

In the dog ear, what is the role of the vestibular organ?

• To detect sound vibrations

• To maintain balance and spatial orientation

• To filter out background noise

• To amplify sound waves

What is the function of the Eustachian Tube?

• Connects the middle ear to the pharynx, equalizing air pressure.

• Enhances hearing sensitivity in certain animals.

• Converts sound waves into mechanical vibrations.

• Amplifies and transfers sound to the inner ear.
