I would most definitely say the cardiac muscle (the heart), as without it, one couldn't live. It is constantly pumping blood (which is oxygen enriched) throughout the body, which provides the necessary nurishment for other body systems and muscles to function.
the heart
In your body.
It's true its the muscle that moves your eyes :)
The busiest muscle is probably the tongue or the jaw muscle because if you eat or talk, you use both. But probably the jaw because there are some sounds you can make without the tongue but both are useful.

the hardest working horse is a appolosa. the hardest working muscle in your body is the heart. it pumps loads of blood through your body every second!
The heart is the busiest organ in the human body as it continuously pumps blood throughout the body to deliver oxygen and nutrients to cells and remove waste products. On average, the heart beats around 60-100 times per minute, resulting in millions of beats over a lifetime.

the most stronger muscle in your body is your leg muscle because it holed everithing in your body.
After you work out, you rip muscle tissue and your body builds the muscle back. Thus, forming muscle on top of muscle.
the ciliary muscle is the smooth muscle of the ciliary body
