Question

Quizplus · Accepted Answer

The Eustachian tube connects the middle ear to the throat, allowing for equalization of pressure on the eardrum.

Answer: B 
 The tympanic membrane, or eardrum, receives and amplifies sound waves.

Answer: G 
 The malleus is a small bone in the middle ear that connects the tympanic membrane to the incus and helps transmit sound vibrations.

Answer: A 
 The Organ of Corti is a structure in the cochlea that contains sensory hair cells responsible for detecting sound waves.

Answer: D 
 The stapes is a bone in the middle ear that transmits sound vibrations from the incus to the inner ear.

Answer: E 
 The semicircular canals are three loops in the inner ear that sense rotational acceleration and help maintain balance.

Answer: F 
 The cochlea is a spiral-shaped structure in the inner ear filled with fluid that converts sound vibrations into neural signals for the brain to interpret.

Answer: H 
 The auricle, or pinna, is the visible external part of the ear that helps direct sound waves into the ear canal.

Answer: I 
 Perilymph is a fluid in the inner ear that cushions and protects the delicate structures involved in hearing and balance.

Answer: J 
 Endolymph is a fluid in the inner ear that helps convey sensory signals to the brain.
