Middle Ear and Sound Perception

The video explores the anatomy and functions of the ear, highlighting its roles in hearing and balance. It explains the structure of the outer, middle, and inner ear, detailing how soundwaves are transmitted and amplified. The video also covers the conversion of mechanical waves to fluid waves in the cochlea and the role of semicircular canals in spatial orientation.

What are the two main functions of the ear?

• Smell and taste

• Balance and smell

• Hearing and balance

• Hearing and taste

What is the technical term for the ear canal?

• Cochlea

• Tympanic membrane

• External auditory meatus

• Semicircular canal

What separates the outer ear from the middle ear?

• Tympanic membrane

• Oval window

• Cochlea

• Pinna

Which bone in the middle ear is directly connected to the tympanic membrane?

• Incus

• Malleus

• Stapes

• Cochlea

By how much is the sound wave amplified after passing through the middle ear bones?

• 10 times

• 15 times

• 22 times

• 30 times

What is the function of the oval window in the ear?

• To detect head movements

• To transfer mechanical waves into fluid waves

• To amplify sound waves

• To separate the outer ear from the middle ear

What structure in the inner ear is responsible for determining the pitch of sound?

• Pinna

• Incus

• Cochlea

• Tympanic membrane

What is the primary role of the semicircular canals?

• Amplifying sound waves

• Hearing

• Detecting chemical stimuli

• Balance and spatial orientation

What happens to the rocks in the semicircular canals when you tilt your head?

• They dissolve

• They fall due to gravity

• They vibrate

• They amplify sound

Why do you feel like you're still spinning after you stop?

• The tympanic membrane is still vibrating

• The oval window is still vibrating

• The fluid in the semicircular canals continues to move

• The cochlea is still processing sound
