Answer

To answer the question regarding the human vertebral column, we need to break down the components of the vertebral column and understand how many individual bones it consists of.

### Step-by-Step Solution:

1. **Identify the Total Number of Vertebrae**:
The human vertebral column is composed of a total of 33 vertebrae. These vertebrae are categorized into different regions:
- Cervical vertebrae: 7
- Thoracic vertebrae: 12
- Lumbar vertebrae: 5
- Sacral vertebrae: 5 (fused)
- Coccygeal vertebrae: 4 (fused)

2. **Understand the Fusion of Vertebrae**:
- The 5 sacral vertebrae fuse to form a single bone called the sacrum.
- The 4 coccygeal vertebrae fuse to form a single bone called the coccyx.

3. **Calculate the Total Number of Bones**:
To find the total number of bones in the vertebral column, we need to account for the fused vertebrae:
- Cervical (7) + Thoracic (12) + Lumbar (5) + Sacrum (1) + Coccyx (1) = 26 bones.

4. **Conclusion**:
Therefore, the human vertebral column is formed of 33 vertebrae and **26 bones**.

### Final Answer:
The human vertebral column is formed of 33 vertebrae and **26 bones**.
