Answer

To answer the question regarding the number of vertebrae present in the cervical, thoracic, lumbar, sacral, and coccyx regions, we can break it down step by step:

### Step-by-Step Solution:

1. **Identify the Regions of the Vertebral Column**:
- The vertebral column is divided into five main regions: cervical, thoracic, lumbar, sacral, and coccyx.

2. **Count the Vertebrae in Each Region**:
- **Cervical Region**: There are 7 cervical vertebrae (C1 to C7).
- **Thoracic Region**: There are 12 thoracic vertebrae (T1 to T12).
- **Lumbar Region**: There are 5 lumbar vertebrae (L1 to L5).
- **Sacral Region**: There is 1 sacral vertebra, which is typically fused to form the sacrum.
- **Coccyx Region**: There is 1 coccygeal vertebra, which is also typically fused to form the coccyx.

3. **Summarize the Counts**:
- Therefore, the number of vertebrae in each region is as follows:
- Cervical: 7
- Thoracic: 12
- Lumbar: 5
- Sacral: 1
- Coccyx: 1

4. **Final Answer**:
- The number of vertebrae present in the cervical, thoracic, lumbar, sacral, and coccyx regions are respectively: **7, 12, 5, 1, 1**.
