What is the Richter Scale. The Richter magnitude scale (often shortened to Richter scale) is the most common standard of measurement for earthquakes. It was invented in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes.
Like most systems in the body, the muscular system does not work in isolation. The most obvious systems that interact with muscular system are the skeletal system, the nervous system and the circulatory system. Muscles are also involved in the digestive system, the respiratory system and the immune system.
Muscular System. The muscular system is composed of more than 600 muscles. These include the involuntary muscles of the heart and the smooth muscles of the internal organs. The skeletal muscles connect to the bones and work with connective tissue at the joints to allow for movement.uscular System. The muscular system is composed of more than 600 muscles.
