SegWit

I understand that in a SegWit transaction, the signature data is extracted from the rest of the transaction data and put into the witness block (extended block). What does signature data imply in a raw transaction? I would insert a photo to show what I mean but that’s not possible. 
Is the signature data in a raw transaction only the “scriptSig”:…..line or is it also the “scriptPubKey”: OP_DUP OP_HASH160….line?
