C2 (cervical vertebra)
C2 (cervical vertebra) C2 is the symbol for the second cervical vertebra, which is also called the axis. It is so-named because the uppermost cervical vertebra (called the atlas) rotates about the odontoid process of the second cervical vertebra. The joint between the axis and atlas is a pivot type of joint. It allows the head turn.
