Which is the busiest muscle in the human body?
Eye muscles are the busiest muscles in the human body.
In order for the brain to get a specific visual picture, the eye fixates and stops moving for a fraction of a second.
The more visual information the brain wants, the more actively the eye moves.
There can be as many as 400-500 mini-movements per second, but scientists estimate the average as two per second or about 173 000 per day.
Here are some typical eye movements made while scanning a face.
Compare this with the heart muscle. A heart rate of 80 beats per minute corresponds to 115 000 beats per day.
Thus, of the 639 muscles in a human body, the eye muscles are the busiest.
