Cervical Vertebrae

The Cervical Vertebrae (pronounced: /ˈsɜːrvɪkəl ˈvɜːrtɪbriː/) are the seven cylindrical bones, or vertebrae, that provide support and structure to the cervical spine. The cervical vertebrae are abbreviated as C1 through C7, top to bottom.

Etymology

The term "cervical" originates from the Latin word "cervix" which means "neck". "Vertebrae" is derived from the Latin word "vertere" meaning "to turn".

Structure

The cervical vertebrae are composed of different parts: the body, the vertebral arch, and seven processes. The first two vertebrae, C1 and C2, are highly specialized and are given unique names: atlas and axis, respectively. Their function is to support the skull, enable head movements and protect the spinal cord.
