The anatomy of the ear for High School Biology 2 classes
Questions and Answers
- 1.
Name the 3 parts of the ear.
- A.
External, middle, inner
- B.
Outside, inner, eardrum
- C.
Middle, inner, eustachian
Correct Answer
A. External, middle, innerExplanation
The ear is divided into three main parts: the external ear, the middle ear, and the inner ear. The external ear consists of the visible part of the ear, known as the pinna, and the ear canal. The middle ear is located behind the eardrum and contains the three smallest bones in the body, called the ossicles, which transmit sound vibrations from the eardrum to the inner ear. The inner ear is responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. It consists of the cochlea, which is responsible for hearing, and the vestibular system, which is responsible for balance.Rate this question:

The tympanic cavity is a small air-filled cavity located in the
- A.
Inner ear
- B.
External ear
- C.
Eardrum
- D.
Middle ear
Correct Answer
D. Middle earExplanation
The tympanic cavity is a small air-filled cavity located in the middle ear. It is surrounded by the eardrum and contains the three smallest bones in the body, known as the ossicles. These bones transmit sound vibrations from the eardrum to the inner ear, where they are converted into electrical signals that can be interpreted by the brain. The middle ear also plays a role in equalizing air pressure on both sides of the eardrum, helping to protect the delicate structures of the inner ear.Rate this question:

The ________________ ear is composed of the pinna and the external auditory canal.
- A.
Middle
- B.
Inner
- C.
External
- D.
Outer
Correct Answer
C. ExternalExplanation
The external ear is composed of the pinna and the external auditory canal. This is the part of the ear that is visible on the outside of the head. The pinna helps to collect sound waves and direct them into the ear canal. The external auditory canal is a tube-like structure that carries the sound waves from the pinna to the middle ear.Rate this question:

Sound waves that enter the external auditory canal eventually hit the tympanic membrane or
- A.
Pinna
- B.
Eardrum
- C.
Cerumen
- D.
External ear
Correct Answer
B. EardrumExplanation
The correct answer is eardrum. When sound waves enter the external auditory canal, they eventually reach the eardrum or tympanic membrane. The eardrum is a thin, cone-shaped membrane that separates the external ear from the middle ear. It vibrates in response to sound waves and transmits these vibrations to the middle ear, where they are further amplified and transmitted to the inner ear for processing.Rate this question:

What are the names of the bones in the inner named for their shape?
Correct Answer
hammer, anvil and stirrupExplanation
The bones in the inner ear are named after their shape. The hammer, also known as the malleus, resembles a hammer, the anvil, also known as the incus, resembles an anvil, and the stirrup, also known as the stapes, resembles a stirrup. These three bones work together to transmit sound vibrations from the eardrum to the inner ear, allowing us to hear.Rate this question:

What is the name of the nerve that transmits impulses to the brain?
Correct Answer
cochlear nerveExplanation
The cochlear nerve is responsible for transmitting auditory information from the cochlea of the inner ear to the brain. It plays a crucial role in our ability to hear and process sound. When sound waves reach the cochlea, the cochlear nerve carries the electrical signals generated by the hair cells in the cochlea to the brain, where they are interpreted as sound. Therefore, the cochlear nerve is the correct answer to the question as it is the specific nerve involved in transmitting impulses related to hearing to the brain.Rate this question:
