Which of the following is associated with hearing in bird?

Options

A. Utriculus
B. Sacculus
C. Lagena
D. Ampulla

Answer

To determine which structure is associated with hearing in birds, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Bird Anatomy**: Begin by recognizing that birds have specialized structures for hearing and maintaining balance. The inner ear plays a crucial role in both hearing and equilibrium.

2. **Identifying Relevant Structures**: The options given are utriculus, succulus, Lagina, and ampulla. We need to identify which of these is specifically associated with hearing.

3. **Function of the Inner Ear**: In birds, the inner ear contains structures that are involved in both hearing and balance. The cochlea is the primary structure responsible for hearing, while the semicircular canals (which include the ampulla) help with balance.

4. **Focus on Lagina**: The term "Lagina" in the context of bird anatomy refers to the lagena, which is a part of the inner ear. It is associated with hearing in birds, as it helps in the perception of sound.

5. **Conclusion**: Based on the functions of the structures mentioned, the correct answer is that hearing in birds is associated with the Lagina.

### Final Answer:
**Hearing in birds is associated with the Lagina.**
