Which one of the following is showing the correct sequential order of vertebrae in the vertebral column of human beings ?

Options

A. Cervical-lumbar-thoracic-lumber-occygeal
B. Cervical-thoracic-sacral-lumbar-occygeal
C. Cervial-sacral-thoracic-lumbar-coccygeal
D. Cervical-thoracic-lumar-sacral-cocygeal

Answer

To determine the correct sequential order of vertebrae in the vertebral column of human beings, we need to understand the structure and classification of the vertebrae. The human vertebral column is divided into different regions, each consisting of a specific number of vertebrae. Here is the step-by-step solution:

### Step 1: Identify the Regions of the Vertebral Column
The vertebral column is divided into five main regions:
1. Cervical Region
2. Thoracic Region
3. Lumbar Region
4. Sacral Region
5. Coccygeal Region

### Step 2: Count the Number of Vertebrae in Each Region
- **Cervical Region**: 7 vertebrae
- **Thoracic Region**: 12 vertebrae
- **Lumbar Region**: 5 vertebrae
- **Sacral Region**: 5 fused vertebrae
- **Coccygeal Region**: 4 fused vertebrae

### Step 3: Establish the Correct Sequential Order
The correct sequential order of the vertebrae from the top to the bottom of the vertebral column is:
1. Cervical
2. Thoracic
3. Lumbar
4. Sacral
5. Coccygeal

### Final Answer
The correct sequential order of vertebrae in the vertebral column of human beings is:
**Cervical → Thoracic → Lumbar → Sacral → Coccygeal**
