What does the c wave and the v wave actually represent on the jugular venous pulse?

The c wave, which occurs simultaneously with the carotid arterial pulse, is an inconstant wave in the jugular venous pulse and/or interruption of the descent following the peak of the 'a' wave (many investigators refer to this wave as the 'x'' descent). The 'v' wave results from the rise in right atrial pressure when blood flows into the right atrium during ventricular systole when the tricuspid valve is shut, and the 'y' descent, ie, the down slope of the 'v' wave, is related to the decline in right atrial pressure when the tricuspid valve reopens.
so c wave=carotid arterial pulse
v wave=rise in right atrial press during ventricular systole

This is how I see it"
c wave- S1, tricuspid valve is closed "bulging of the tricuspid"
[Electophysiologically I think its due to twisting of the ventricles
after the AV valves open]
v wave--begining of S2, filling of the R atrium, tricuspid is closed,
terminates when the tricuspid opens
On my diagram I have the x after the c and the y after the v
comments welcome

dxpxtx, i have read this explaination of c wave somewhere but i was strongly condemned by my professor of medicine. exaplanation given bt mjl is widely accepted and i have references for it too.
