After the resurrection....?

I am Jewish but know a good deal about Christian teachings. But a question came up the other night that I could not answer. I know that Jesus is believed to have been resurrected after his death. At the resurrection was he actually alive again in human form? Was he just seen in visions? Or was he some sort of spirtual presence? If he was alive again in a corporal form, then what happened to him? I appreciate your help.
