Centre for controlling respiration lies in

Options

A. cerebrum
B. medulla oblongata
C. thalamencephalon
D. mid brain

Answer

To answer the question "Centre for controlling respiration lies in," we will analyze the options provided and determine which part of the brain is responsible for controlling respiration.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- A) Cerebrum
- B) Medulla Oblongata
- C) Thalamus
- D) Midbrain

2. **Analyze Each Option**:
- **Cerebrum**: The cerebrum is the largest part of the brain and is primarily responsible for higher brain functions such as movement coordination and temperature regulation. It does not control respiration.
- **Medulla Oblongata**: The medulla oblongata is located at the base of the brain and is responsible for controlling autonomic functions, including heartbeat and respiration. This is a critical area for involuntary control.
- **Thalamus**: The thalamus acts as a relay station for sensory and motor signals but does not control respiration.
- **Midbrain**: The midbrain is involved in functions such as vision, hearing, and regulating sleep-wake cycles, but it does not play a direct role in respiration control.

3. **Conclusion**: Based on the analysis, the part of the brain that controls respiration is the **Medulla Oblongata**.

### Final Answer:
The centre for controlling respiration lies in the **Medulla Oblongata**.
