On well vascularised skin, non infected wounds, best with skin matching texture and colour

What are the 4 types of skin flap for reconstructive surgery and describe them?

Random pattern flaps - no specific blood vessel
Axial flap - skin supplied by specific blood vessel and it accompanying venae comitans
