Human Ear Function and Anatomy

This video tutorial explains the structure and function of the human ear. It covers how the ear converts sound waves into electrical signals that the brain interprets as sound. The ear is divided into three main parts: the outer ear, middle ear, and inner ear. Each part plays a crucial role in the process of hearing. The outer ear collects sound, the middle ear amplifies it, and the inner ear converts it into signals sent to the brain. The video also details the components of each ear section and their specific functions in the hearing process.

What is the primary function of the human ear?

• To amplify sound

• To produce sound

• To convert sound into electrical signals

• To store sound

Which part of the ear is responsible for collecting sound from the environment?

• Middle ear

• Inner ear

• Outer ear

• Auditory nerve

What are the three main parts of the human ear?

• Pinna, hammer, cochlea

• Eardrum, cochlea, auditory nerve

• Outer ear, middle ear, inner ear

• Auditory canal, stirrup, brain

What is the role of the pinna in the outer ear?

• To amplify sound

• To collect sound

• To convert sound into electrical signals

• To transmit sound to the brain

What happens when a compression of the medium reaches the eardrum?

• The eardrum moves outward

• The eardrum vibrates

• The eardrum moves inward

• The eardrum stops moving

Which bones are involved in amplifying sound vibrations in the middle ear?

• Cochlea, pinna, auditory nerve

• Hammer, anvil, stirrup

• Pinna, hammer, cochlea

• Eardrum, cochlea, stirrup

What is the function of the cochlea in the inner ear?

• To collect sound

• To transmit sound to the eardrum

• To amplify sound

• To convert pressure variations into electrical signals

How does the brain interpret the signals received from the auditory nerve?

• As pressure variations

• As sound

• As electrical signals

• As vibrations

What is the role of the auditory nerve?

• To collect sound

• To convert sound into electrical signals

• To amplify sound

• To transmit electrical signals to the brain

Which part of the ear is responsible for turning pressure variations into electrical signals?

• Outer ear

• Middle ear

• Auditory canal

• Inner ear
