Question 1

Match the following:
A) Otoliths
B) Vestibule
C) Pharyngotympanic tube
D) Tympanic membrane
-Contains utricle and saccule.

Accepted Answer

The vestibule contains the utricle and saccule, which both play a role in balance and orientation. Otoliths are small calcium carbonate crystals found in the utricle and saccule, but they are not a structure within the ear. The pharyngotympanic tube, also known as the Eustachian tube, connects the middle ear to the nasopharynx and helps equalize pressure. The tympanic membrane, also known as the eardrum, separates the outer ear from the middle ear.

Accepted Answer

The tympanic membrane, also known as the eardrum, separates the external acoustic meatus (ear canal) from the middle ear.

Note: 
A) Otoliths refer to the small calcium carbonate crystals located in the inner ear that play a role in balance and orientation.
B) Vestibule refers to a part of the inner ear that helps with balance and contains the utricle and saccule.
C) Pharyngotympanic tube, also known as the Eustachian tube, connects the middle ear to the back of the throat and helps regulate pressure in the middle ear.

Ear stones are also known as otoliths, which are calcium carbonate crystals found in the inner ear.

Answer: B 
 The vestibule is a part of the inner ear that contains the utricle and saccule, which are responsible for detecting changes in head position and linear acceleration.
