Epistropheus
the second cervical vertebra in reptiles, birds, and mammals, including humans, in which case it is also called the axis. Unlike the other vertebrae, the anterior (in humans, superior) surface of the epistropheus has a toothlike process around which the first cervical vertebra (atlas) rotates.
