How many cervical vertebrae are present in the human body?

The correct answer is: 7

The human body contains seven cervical vertebrae, which are labeled C1 to C7. These vertebrae are located in the neck region and play a crucial role in supporting the skull, allowing for head movement, and protecting the spinal cord. The first cervical vertebra, known as the atlas, supports the globe of the skull and allows for nodding motions, while the second, known as the axis, enables rotational movement of the head. This unique structure and number of cervical vertebrae are vital for both mobility and stability in the neck region, making them a key area of study in anatomy and emergency care.
