Hello, When the lumbricals are working (MCP joint movement of the fingers),does that mean that the FDP or FDS are not working at all,or do they assist with the movement? -How come the lumbricals are more powerful than the forearm's muscles if they are connected to the tendons of both the FDP and the extensors ? Thanks
