They are considered voluntary muscles. They are generally divided into two sets:
This is often remembered by the mnemonic PAD-DAB, as the Palmar interosseous muscles ADduct, and the Dorsal interosseous muscles ABduct. The axial line goes down the middle of the 3rd digit, towards the palm of the hand (it's an imaginary line).
