What is a C3-4?

C3-4 refers to the third and fourth cervical vertebrae in the neck region of the spine. These vertebrae are part of the cervical spine, which consists of seven vertebrae labeled C1 to C7. The C3-4 junction is significant because it plays a crucial role in supporting the head and facilitating neck movement, while also protecting the spinal cord and nerve roots. Injuries or conditions affecting this area can lead to various neurological symptoms or mobility issues.
