[dm-crypt] From /dev/mapper to the real device

I have searched through the manuals without finding an answer.

I did something like that:
cryptsetup luksOpen /dev/mapper/lv_device crypto_device

I would like to find a way, given /dev/mapper/crypto_device, to find
which lv_device it was built from.

Is there a command or a way to find this information back ?
A sort of mount command for the dm-crypt.

Thank you very much,
