Either metacarpals and phalanges or phalanges and phalanges.

Step-by-step explanation:

You can't tell without the picture but the joints between the metacarpals (the bones in the main part of your hand) and the phalanges (your fingers) are knuckles. They are your first knuckles/major knuckles. The joints between you first/proximal phalanx (longest finger bone) and your second/intermediate phalanx (middle finger bone) and your second/intermediate phalanx and last/distal phalanx (tip of your finger) are your second and third/minor knuckles.
