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.
The muscular system is often considered in conjunction with the skeletal system, and called the muscular-skeletal system. Understanding the components of the muscular system, including the various types of connective tissues, is a good way to understand how bodies and physical movement work.
