Which part is involved in movement of head to locate and detect the source of a sound ?

Options

A. Superior colliculi
B. Inferior colliculi
C. Pons
D. Medulla oblongata

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which part of the brain is involved in the movement of the head to locate and detect the source of a sound.

2. **Identifying Relevant Brain Parts**: The options provided include parts of the brain. The relevant parts in this context are likely to be from the hindbrain and midbrain.

3. **Analyzing the Hindbrain**: The hindbrain consists of structures such as the pons and medulla oblongata. However, these structures primarily regulate basic life functions like respiration and heart rate, not specifically the movement of the head in response to sound.

4. **Examining the Midbrain**: The midbrain contains structures known as the colliculi, specifically the superior and inferior colliculi. These are important for reflexive movements.

5. **Distinguishing Between Colliculi**:
- The **superior colliculi** are involved in visual reflexes.
- The **inferior colliculi** are responsible for auditory reflexes, which include the movement of the head to locate the source of a sound.

6. **Conclusion**: Since the inferior colliculi are responsible for audio reflexes and head movement in response to sound, they are the correct answer to the question.

7. **Final Answer**: The part of the brain involved in the movement of the head to locate and detect the source of a sound is the **inferior colliculi**.
