register of pic

we know that there are many SFRs in PIC, like WREG and this is the register that is mainly involved in arithematic options, but all of them belong to the RAM, the dont reside inside the processor,the question is are there registers inside the cpu of pic microcontoller like 8086 microprocessor that has many registers in its cpu ?

No, the only processor register is the work (W) register. However, you can think of the ram as registers as you can do various things on them without effecting the W register. For example, incf 0x23,F will add 1 to location 0x23 which is the same as other processors register based instructions.
