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-sacral-coccygeal
B. Cervical-thoracic-sacral-lumbar-coccygeal
C. Cervical-sacral-thoracic-lumbar-coccygeal
D. Cervial-thoracic-lumbar-sacral-coccygeal

Explanation

To determine the correct sequential order of vertebrae in the vertebral column of human beings, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Vertebral Column**: The vertebral column, also known as the spine or backbone, is made up of multiple vertebrae. It serves as a structural framework for the torso and protects the spinal cord.

2. **Identify the Types of Vertebrae**:
- **Cervical Vertebrae**: There are 7 cervical vertebrae located in the neck region.
- **Thoracic Vertebrae**: There are 12 thoracic vertebrae located in the chest region.
- **Lumbar Vertebrae**: There are 5 lumbar vertebrae located in the lower back.
- **Sacral Vertebrae**: These vertebrae are fused to form a single bone called the sacrum.
- **Coccygeal Vertebrae**: These are also fused to form a single bone known as the coccyx (or tailbone).

3. **Arrange in Sequential Order**:
- Start with the cervical vertebrae (C).
- Follow with the thoracic vertebrae (T).
- Next are the lumbar vertebrae (L).
- Then comes the sacral vertebrae (S).
- Finally, the coccygeal vertebrae (Co).

4. **Final Sequence**: The correct sequential order of the vertebrae in the vertebral column is:
- **Cervical (C)** → **Thoracic (T)** → **Lumbar (L)** → **Sacral (S)** → **Coccygeal (Co)**.

5. **Select the Correct Option**: Based on the options provided, the correct answer is option D, which lists the vertebrae in the order: Cervical, Thoracic, Lumbar, Sacral, and Coccygeal.
