Cochlear Function and Hearing Process

The video explains the process of hearing, detailing how sound waves are collected, amplified, and converted into electrical signals by the ear. It covers the anatomy of the ear, including the outer, middle, and inner ear, and the role of the cochlea and organ of Corti in sound conversion. The video also highlights the importance of understanding hearing for exams, focusing on key terms and concepts.

What is the primary function of the ear in the hearing process?

• To produce sound waves

• To convert sound energy into electrical energy

• To store sound waves

• To amplify electrical signals

Which part of the ear is responsible for collecting sound waves?

• Cochlea

• Tympanic membrane

• Stapes

• Pinna

What is the role of the tympanic membrane in hearing?

• It transmits sound to the brain

• It converts sound waves into electrical signals

• It amplifies sound waves

• It collects sound waves

What is the function of the cochlea in the hearing process?

• To transmit sound to the auditory nerve

• To convert sound waves into electrical signals

• To collect sound waves

• To amplify sound waves

Which structure within the cochlea is responsible for converting sound waves into electrical energy?

• Organ of Corti

• Tympanic membrane

• Auditory nerve

• Pinna

What happens when the endolymph moves in the cochlea?

• It amplifies sound waves

• It causes hair cells to bend

• It collects sound waves

• It transmits sound to the brain

What is the result of hair cells bending in the cochlea?

• Sound is transmitted to the outer ear

• Sound waves are collected

• Electrical signals are generated

• Sound waves are amplified

Which ions are involved in generating electrical signals in the cochlea?

• Chloride ions

• Potassium ions

• Calcium ions

• Sodium ions

What is the role of the auditory nerve in the hearing process?

• To collect sound waves

• To amplify sound waves

• To transmit electrical signals to the brain

• To convert sound waves into electrical signals

Which part of the cochlea responds to high-pitched sounds?

• Base of the cochlea

• Apex of the cochlea

• Middle ear

• Outer ear
