How many cervical vertebrae are located in the neck?

The cervical spine consists of seven cervical vertebrae, which are designated C1 through C7. These vertebrae play a crucial role in supporting the skull, facilitating head movement, and protecting the spinal cord. The configuration of these seven vertebrae allows for a wide range of motion in the neck, including flexion, extension, rotation, and lateral bending. This anatomical structure is essential for maintaining both stability and flexibility in the cervical region, making it vital for overall head and neck function. Understanding the number of cervical vertebrae is fundamental in physical therapy, as it allows technicians and therapists to properly assess and address conditions that may affect neck mobility and spinal health.
