Muscle fibers are in turn composed of myofibrils. The myofibrils are composed of actin and myosin filaments, repeated in units called sarcomeres, the basic functional units of the muscle fiber.The sarcomere is responsible for the striated appearance of skeletal muscle, and forms the basic machinery necessary for muscle contraction.uscle fibers are in turn composed of myofibrils.

Wyoming's population in 2016 is estimated at 586,107, up slightly from the 2010 Census. It's currently enjoying a healthy growth rate of 1.13%, which ranks 15th among all 50 states. The population of Wyoming in 2016 can only be estimated at present because the last official census in the country took place in 2010.
Best Answer: As of the 2008 census estimate, it was Wyoming with 532,668 people. As far as the most unpopulated city, (assuming you'd accept towns, villages, etc as well), I've passed through a city in Central Texas with a sign Population: 2. No idea what the name of it was. I'm sure it's not listed anywhere. I'm sure there are tons of cities like that with that low of populations.
