Question

Quizplus · Accepted Answer

The cochlea is the snail-shaped structure that contains the organ of Corti, which is responsible for converting sound vibrations into signals that can be sent to the brain.

Answer: A
 The organ of Corti is the structure within the cochlea that contains the sensory receptors for hearing.

Answer: B
 The tympanic membrane, also known as the eardrum, is a thin membrane that vibrates in response to sound waves, which then sets in motion the bones of the middle ear.

Answer: D
 The stapes is one of the three small bones in the middle ear that transmit sound vibrations from the eardrum to the inner ear.

Answer: E
 The semicircular canals are structures within the inner ear that are responsible for sensing changes in head movement and balance.

Answer: G
 The malleus is one of the three small bones in the middle ear that transmit sound vibrations from the eardrum to the inner ear.

Answer: H
 The auricle, also known as the pinna, is the outer visible part of the ear that helps to collect sound waves.

Answer: C
 The Eustachian tube is a narrow tube that connects the middle ear to the back of the throat, and helps to equalize pressure within the ear.

Answer: I 
 Perilymph is the fluid that fills the space between the bony and membranous labyrinth of the inner ear.

Answer: J
 Endolymph is the fluid that fills the membranous labyrinth within the inner ear, and plays a key role in transmitting sound vibrations to the sensory receptors within the organ of Corti.
