What is 4?
Correct Answer
D. Malleus
2.
What is 5?
Correct Answer
C. Stapes
Explanation
The correct answer is "stapes." The stapes is one of the three small bones in the middle ear, also known as the ossicles. It is commonly referred to as the "stirrup" due to its shape. The stapes is connected to the oval window, which is a membrane-covered opening that leads to the inner ear. When sound waves enter the ear, they cause the eardrum to vibrate, which in turn causes the ossicles, including the stapes, to transmit these vibrations to the inner ear. This process allows us to perceive and interpret sound.

What is 8?
Correct Answer
B. Oval window
Explanation
The oval window is a structure in the ear that separates the middle ear from the inner ear. It is responsible for transmitting sound vibrations from the middle ear to the fluid-filled cochlea in the inner ear. The other options mentioned in the question (round window, external acoustic meatus, and stapes) are all parts of the ear, but they do not specifically relate to the function of transmitting sound vibrations. Therefore, the correct answer is oval window.

What is number 1?
Correct Answer
A. Auricle
Explanation
The auricle is the external part of the ear that is visible on the side of the head. It is responsible for collecting sound waves and directing them into the ear canal. The auditory tube is a tube that connects the middle ear to the back of the throat, allowing for equalization of pressure. The pharynx is the part of the throat that connects the mouth and nasal cavity to the esophagus and larynx. The stapes is one of the three small bones in the middle ear that transmit sound vibrations from the eardrum to the inner ear.

What is 10?
Correct Answer
C. Tympanic cavity
Explanation
The tympanic cavity is the correct answer because it is a part of the ear. It is a small, air-filled space located in the middle ear, behind the eardrum. It is responsible for transmitting sound vibrations from the eardrum to the inner ear.

What is 13?
Correct Answer
B. Eardrum
Explanation
The eardrum, also known as the tympanic membrane, is a thin, cone-shaped membrane that separates the external ear from the middle ear. It plays a crucial role in the process of hearing by vibrating in response to sound waves, which then transmit the vibrations to the middle ear. The eardrum is an essential component of the auditory system and is responsible for converting sound waves into mechanical vibrations that can be further processed by the inner ear.

What is number 2?
Correct Answer
B. Semicircular Canals
Explanation
The correct answer is Semicircular Canals. The semicircular canals are part of the inner ear and play a crucial role in our sense of balance. They are three fluid-filled tubes that are positioned at right angles to each other. When we move our head, the fluid inside the canals moves, and this movement is detected by hair cells, which send signals to the brain to help us maintain our balance. The other options listed in the question, such as incus, cochlea, and eardrum, are all parts of the ear but are not directly related to the sense of balance.
