The hole on the axis of the human vertebrae is known as the vertebral foramen. It is part of the vertebral arch and serves as a passageway for the spinal cord and associated nerves. In the case of the axis specifically (the second cervical vertebra), this foramen allows for the rotation of the atlas (the first cervical vertebra) around the odontoid process, or dens, enabling head movement.

What are the two most superior vertebrae?
The two most superior vertebrae are CERVICAL vertebrae 1 and 2 (C1 and C2). They are also known as the Atlas (C1) and Axis (C2). These two vertebra join together to form the atlantoaxial joint, which helps with the movement of the neck. A structure on the axis called the dens (odontoid process) fits through a foramen (hole) in the atlas to join them together.
