D. 1

Answer

To determine the number of anterior curves present in the human vertebral column, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Vertebral Column**:
The human vertebral column is an S-shaped structure that consists of various curves. It is important to differentiate between the anterior and posterior curves.

2. **Identify the Anterior Curves**:
The anterior curves of the vertebral column are the curves that curve forward. In humans, there are two main anterior curves:
- The **cervical curve**: This is located in the neck region.
- The **lumbar curve**: This is located in the lower back region.

3. **Identify the Posterior Curves**:
For completeness, it is also essential to recognize the posterior curves:
- The **thoracic curve**: This is located in the upper back region.
- The **sacral curve**: This is located in the pelvic region.

4. **Count the Anterior Curves**:
From the identification in step 2, we see that there are two anterior curves: the cervical curve and the lumbar curve.

5. **Conclusion**:
Therefore, the total number of anterior curves present in the human vertebral column is **2**.

### Final Answer:
The number of anterior curves present in the human vertebral column is **2**.
