So far, we have recorded EMG signals from three fingers. Below are the diagrams for the three muscles we have recorded, highlighted in green. They are extrinsic muscles, responsible for the extension of fingers but located in the forearm.

Extensor Digiti Minimi: Responsible for pinky extension.

Extensor Digitorum: Responsible for the extension of the four fingers, not including the thumb.

Extensor Pollicis Brevis: Responsible for the extension of the thumb.
