The center for heartbeat regulation is present in

Options

A. Pons varolii
B. Cerebrum
C. Cerebellum
D. Medulla

Answer

To determine the center for heartbeat regulation, we need to analyze the options provided:

1. **Pons Varolii**: This structure is primarily involved in regulating respiration. It helps maintain the rhythm of breathing but does not directly control the heartbeat.

2. **Cerebrum**: The cerebrum is responsible for higher brain functions, including voluntary movements and cognitive processes. It does not regulate heartbeat.

3. **Cerebellum**: The cerebellum is mainly involved in coordination, balance, and posture. It does not play a direct role in heartbeat regulation.

4. **Medulla Oblongata**: The medulla oblongata is a crucial part of the brainstem that controls autonomic functions, including heart rate and blood pressure. It contains the cardiac center, which regulates the heartbeat by sending signals to the heart.

Based on this analysis, the center for heartbeat regulation is located in the **Medulla Oblongata**.

**Final Answer**: The center for heartbeat regulation is present in the Medulla Oblongata.
