It is usually taken to mean relative movement between the upper jaw and the braincase. [1] Most vertebrates have some form of a kinetic skull. [1]

[a] Temporal fenestrae are openings in the temporal region of the skull of some amniotes, behind the orbit (eye socket).

A schematic of an anapsid skull showing the location of major dermal bones of the upper skull, including the quadrate bone (q).. The quadrate bone is a skull bone in most tetrapods, including amphibians, sauropsids (reptiles, birds), and early synapsids.
