In human body muscular co-ordination is controlled by:

Options

A. Spinal cord
B. Cortex
C. Cerebellum
D. Cerebral hemisphare

Answer

To answer the question "In the human body, muscular coordination is controlled by:", we will analyze each option provided and determine which one is responsible for muscular coordination.

### Step-by-Step Solution:

1. **Understanding the Options**:
- The options given are: Spinal Cord, Cortex, Cerebellum, and Cerebral Hemisphere. We need to evaluate each option to see which one is primarily responsible for muscular coordination.

2. **Evaluating the Spinal Cord**:
- The spinal cord is involved in reflex actions and basic motor functions. It helps in controlling certain involuntary actions like breathing and coughing, but it does not primarily coordinate complex muscular movements. Thus, it is not the best answer for muscular coordination.

3. **Evaluating the Cortex**:
- The cortex, specifically the cerebral cortex, is responsible for higher brain functions such as memory, perception, and problem-solving. While it plays a role in voluntary muscle control, it does not directly coordinate muscle movements. Therefore, it is not the correct answer for muscular coordination.

4. **Evaluating the Cerebellum**:
- The cerebellum is a part of the hindbrain and is crucial for coordinating voluntary movements. It receives information from the sensory systems and spinal cord, allowing it to regulate motor movements effectively. The cerebellum is responsible for maintaining posture, balance, and smooth coordination of muscles during activities like walking and running.

5. **Conclusion**:
- Based on the evaluations, the cerebellum is the primary structure that controls muscular coordination in the human body. Therefore, the correct answer is **Cerebellum**.

### Final Answer:
Muscular coordination in the human body is controlled by the **Cerebellum**.
