The ________ pass these vibrations through the auditory nerve towards the brain.

Options

A. cochlea
B. ear drum
C. tympanum
D. ear canal

Answer

To solve the question, we need to identify which part of the ear is responsible for passing vibrations through the auditory nerve to the brain. Here’s the step-by-step solution:

### Step 1: Understand the components of the ear
The ear consists of several parts, including the outer ear (ear canal), the middle ear (eardrum), and the inner ear (cochlea).

### Step 2: Identify the function of each part
- **Eardrum**: It vibrates when sound waves hit it, but it does not send vibrations to the brain directly.
- **Cochlea**: This is a spiral-shaped organ in the inner ear that converts sound vibrations into electrical signals.
- **Auditory nerve**: This nerve carries the electrical signals from the cochlea to the brain.
- **Ear canal**: This is the passage that leads to the eardrum but does not process vibrations.

### Step 3: Determine which part passes vibrations to the auditory nerve
The cochlea is responsible for transforming the vibrations into signals that can be interpreted by the brain. Therefore, it is the cochlea that passes these vibrations through the auditory nerve.

### Step 4: Finalize the answer
Based on the analysis, the correct answer to the question is **Cochlea**.

### Final Answer:
The **Cochlea** pass these vibrations through the auditory nerve towards the brain.
