G0 phase

Many mammal cells, such as this neuron, remain permanently or semipermanently in G0.

The G0 phase, G zero phase, or 'resting phase' is a period in the cytokinesis are also often considered to be in the G0 stage.[1] On occasion, a distinction in terms is made between a G0 cell and a 'quiescent' cell (e.g., heart muscle cells and neurons), which will never enter the G1 phase, whereas other G0 cells may.

Cellular senescence is distinct from quiescence because it is a state that occurs in response to DNA damage or degradation that would make a cell's progeny nonviable. Senescence then, unlike quiescence, is often a biochemical alternative to the self-destruction of such a damaged cell by apoptosis. Furthermore, quiescence is reversible whereas senescence isn't.
