Options

A. Maintaining posture
B. Controlling learning
C. Regulation of heartbeat
D. Regulation of body temperature

Answer

**Step-by-Step Solution:**

1. **Understanding the Medulla Oblongata**: The medulla oblongata is a part of the brainstem that plays a crucial role in autonomic functions.

2. **Analyzing the Options**:
- **Option C: Maintaining Posture**: This function is primarily associated with other parts of the brain, such as the cerebellum, rather than the medulla oblongata.
- **Option D: Controlling Learning**: Learning and memory functions are predominantly managed by the cerebral cortex and other brain structures, not the medulla oblongata.
- **Option E: Regulation of Heartbeat**: This is a key function of the medulla oblongata. It contains vital centers that control the heart rate and the force of heart contractions, thereby regulating blood circulation.
- **Option F: Regulation of Body Temperature**: The hypothalamus is responsible for regulating body temperature, not the medulla oblongata.

3. **Conclusion**: After analyzing all the options, the correct function performed by the medulla oblongata is the regulation of heartbeat.

**Final Answer**: The function performed by the medulla oblongata is the regulation of heartbeat.
