Odontoid process is present with which vertebrae of vertabral column ?

Options

A. Atlas vertebrae
B. Axis vertebrae
C. Vertebrae prominens
D. Lumber vertebrae

Answer

### Step-by-Step Solution:

1. **Understanding the Vertebral Column**: The vertebral column is divided into five sections: cervical, thoracic, lumbar, sacrum, and coccyx. Each section has specific characteristics and functions.

2. **Identifying the Cervical Region**: The cervical region consists of seven vertebrae (C1 to C7). The first two cervical vertebrae are known as the atlas (C1) and the axis (C2).

3. **Defining the Odontoid Process**: The odontoid process, also known as the dens, is a bony projection that arises from the second cervical vertebra, which is the axis.

4. **Locating the Axis Vertebra**: The axis (C2) is crucial for the rotation of the head and neck. The odontoid process allows the atlas to pivot around it, enabling head movements.

5. **Conclusion**: Therefore, the odontoid process is present on the axis vertebra (C2) of the vertebral column.

### Final Answer:
The odontoid process is present with the axis vertebra (C2) of the vertebral column.
