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 Physiology. The main function of the muscular system is movement. Muscles are the only tissue in the body that has the ability to contract and therefore move the other parts of the body. Related to the function of movement is the muscular systemâs second function: the maintenance of posture and body position. Muscles often contract to hold the body still or in a particular position rather than to cause movement.
