Cervical vertebrae - Definition

Ask a question


The cervical vertebrae are located in the neck. There are seven cervical vertebrae in humans. They carry the weight of the head and enable its mobility as well as that of the neck. They can flex, extend, bend to either side, and rotate right or left. Cervical pain, often called neck pain, is common. It can be due to the wear and tear of the intervertebral spaces, osteoarthritis (called cervical spondylosis), the displacement of a vertebra, or nerve compression.
