I am a 5ft 10in tall 16y/o boy. My arms are 31in long. My legs are 41in long, and my torso is 19in long. Does this mean that I will continue to grow?

Possibly. Even with you providing your current measurements, it is impossible to predict your final adult height. Ultimately genetic plays the most powerful role in determining your final adult height so look to your parents for a rough estimate. Of course good nutrition, lots of sleep, and a nurturing environment as a child can effect total height. Also depends on where you are with physical development.
