Actually, the strongest muscle is the masseter.
Depends on how you define "strongest". The masseter is the strongest relative to its mass, but in terms of absolute strength, it's the quadriceps or the gluteus maximus that holds the crown (in part due to their sheer size). Meanwhile, the external muscles of the eye constantly readjust the position of the eyeball, making as much as 10,000 movements in a single hour while reading. And if we define "strength" as "hardest working", most experts agree that the title belongs to the heart, as it never stops beating throughout a person's life, with the average heart rate being 60-100 bpm (so the aforementioned eye muscles may be able to do a lot more movements in an hour, but they can't sustain it for long and need to rest every once in a while, whereas the heart never takes a break). And then there's the soleus, a muscle just below the calf muscle that is said to possess the absolute greatest pulling force in the entire human muscular system, which it uses to constantly battle against gravity to keep the human being upright.
Also, anyone who claims the tongue is the "strongest" muscle in any way is wrong on at least one vital fact: The tongue is composed of not a single muscle, but eight separate ones.
